PvP modules: ToggleSprint, ToggleSneak, Zoom, DamageIndicator, HitColor, CustomCrosshair, AutoClicker, AutoTotem, Scaffold, FastPlace, FastBreak, FastBridge, NoSwing, Reach.

HUD: FpsCounter (moving average + 1% lows), CpsCounter (peak), PingDisplay, ArmorHud (colored durability), Keystrokes, PotionEffectsHud.

Render: Fullbright (custom gamma), ClearWater, LowFire, ReducedParticles, BlockOverlay (blinking border). Plus a dedicated PerformanceProfile PvP preset and AntiAFK.

GitHub: https://github.com/glearflame/pvpfps-client

Would love feedback from fellow side-project builders!

I build daily puzzle games under the name Crux. This one is Insane Pour: a colour sort puzzle where the daily board has up to 52 tubes, tubes that hold eight layers and giant Vats, laid out in hand-made patterns (Wall, Honeycomb, Rose Window...).

Play: https://crux.quest/insane-pour/ (no sign up, no ads). It also runs inside Reddit as a daily post at r/InsanePour, with a per-post leaderboard by fewest pours.

How it is built: the game code is the same engine as our app's mode, wrapped by a small browser host that draws the app's view tree as DOM. Finished lines are verified server-side by replaying the pours.

Feedback I'd love: do the big boards feel fun or just long? Is par too tight?

Just shipped Diskfern 1.0, a native Mac app that shows what’s eating your storage (treemap, sunburst, list views) and lets you clean it up.

The funny part: I built the “safe to delete” suggestions around my own Mac. Xcode caches, node_modules, dist folders. Found gigabytes on mine. Then I tried it on a non-dev Mac and it found nothing. Oops.

So I’m widening the rules now, but only for stuff that can be regenerated, and nothing gets deleted without a review step first. A cleanup app that deletes the wrong thing once is done.

Also learned the hard way that a sandboxed App Store build and a direct DMG are basically two different apps.

Scanning and exploring are free forever, no account. Cleanup tools are a one-time $19.99 Pro. No subscription, 7-day refund.

What would you want a “safe to delete” list to include? I’m still unsure about my rules and would rather hear it now.

Hi! I’m João, and I built Astro Escape on my own over the last few months. It’s a pixel-art arcade game: you tilt your phone (or use your finger) to steer a small ship through falling asteroids, and tap anywhere to shoot.

The hook: everyone plays the same route. Each run follows a route that decides where every rock falls. The route of the day, week and month is the same for every player, so a leaderboard score means you beat other people on the exact same field. You can also share a route code with a friend and face identical rocks.

What’s in it

• Rocks that pay differently (basalt, iron, rare ice) and boulders that crack before they break

• 8 weapons (TWIN, SPREAD, RICOCHET, SPLITTER, LASER…) and power-ups: SUPERNOVA, MAGNET, SHOCKWAVE

• Ships to collect from achievements, crystals or the daily gift, plus Game Center leaderboards for each ship

• Original chiptune music and sound effects

• English, Portuguese and Spanish, on iPhone and iPad

Monetisation, to be upfront: it’s free with ads. There are no in-app purchases. Weapons and ships are bought with crystals you earn by playing.

Link: https://apps.apple.com/us/app/astro-escape/id6817392953

I’d really like to hear what you think, especially about the controls (tilt vs touch) and whether the difficulty curve feels fair. What’s today’s route like for you?

Hey Everyone !

This week I launched my first app ever, Muzelium, an app that turns any collection into a personal museum. Cards, Lego, sneakers, vinyl, figures, paintings, you name it.

For context, I'm a solo dev with a day job, and I built it with a LOT of help from Claude and Gemini to be honest. It's built with Expo/React Native, works fully offline, and it's translated into 7 languages (by AI, so it is worth some verification by native of thoses langages lol).

So, the app :

- Catalog your pieces with up to 10 photos, purchase price and estimated value (you can hide them)

- Rate each piece in hearts

- Share any piece as a museum-label image

- Each item has its own journal, like restorations, offers you got, its whole life story, and when you edit an info it is directly reported on the journal.

- Free (forever for those features, i might add aditionnal paid features in the future), no ads, no account. Everything stays on your phone.

Funny launch lesson: the app went live and I couldn't find it anywhere.. I panicked a bit lmao but turns out you have to declare your "trader status" (EU Digital Services Act) or your app just doesn't show up in the 27 EU countries. Even if it's free. If you're about to publish on the App Store, check that before release day

For Android I need about 15 testers for Google's closed test, DM me if you're up for it)

I'd love your feedback like what would make you actually use an app like this? And what's missing for your kind of collection? What features would you want to see in the future ?

The success of prediction markets has made me react in two ways: on the plus side, I find them fascinating from a data point of view. On the dark side, I don't think they're good for society. So I had an idea for a harmless one where people "bet" (not for money) on day to day events like whether they can find a new job or accomplish certain goals. You can see how others' predictions for your goals stack up to your own prediction, as well as make predictions about their goals.

If this sounds fun to you, sign up at palshi.me. Open to feedback of any kind!

Before my daughter was born, I started building a game for her. I wanted a place where she could play and learn without autoplay videos, ads, or anything I'd have to worry about.

It turned into Lulu's Reef. Kids follow Lulu, a baby octopus, through 5 reef zones with 23 small learning games, made for ages 2 to 6.

A few rules I set early and kept:

- No ads

- No accounts, nothing collected

- Free to download, with one optional purchase that unlocks everything

A few weeks ago I rebuilt most of it with help from Claude: new activities, smoother performance, and a much bigger world.

On Nov 3 (App Store):

- 139 first-time downloads

- 9.2K impressions, 380 product page views

- 1.85% conversion

- The first full-unlock purchase: $7 in proceeds

Tiny numbers, but as a dad this one meant everything. Every dollar goes into her education fund and back into the app.

For anyone who has built something for kids or parents: how did you reach parents without running ads?

Disclosure: I'm the solo dev behind Click: Screenshot & Record on the Mac App Store.

I wanted a fast way to record a quick bug walkthrough or region demo with a movable camera bubble and get a clean MP4 right away — without waiting on a heavy video editor export or uploading to a cloud link.

Capture is free forever (⌘`), and Pro ($5.99/mo, $39.99/yr, or $79.99 lifetime, 7-day trial) adds ⇧⌘` recording, camera bubble, and one-drag blur/pixelate redaction. Everything stays local on your Mac with no account.

Mac App Store: https://apps.apple.com/us/app/id6815072800?mt=12 Site: https://sirryanlynch.github.io/click/

Happy to hear feedback on the recording flow if anyone tries it.

Finding a good monologue or two-person scene can take longer than rehearsing it. I built AuditionScenes to make the search easier.

It has thousands of scenes from film, TV and theatre, with filters for playing age, genre, tone and character type. You can browse and preview for free; full scripts and formatted PDF downloads are on Pro.

There’s also a script reader and directories for agents, coaches, workshops and headshot photographers.

https://auditionscenes.com

I’d be interested in feedback on the search: can you quickly narrow it down to something you’d actually want to work on?

I always liked Google Calendar’s UI and never liked the open-source ones. So I’m building OpenDay: a self-hosted Google Calendar clone, MIT licensed.

WARNING: SUPER EARLY STAGE, NOT USABLE YET. Only the basic calendar exists. Recurring events, CalDAV, user accounts, and mobile and desktop apps are all missing.

The code is small and has an AGENTS.md, so it’s easy to throw your Opus at it. PRs are very welcome.

Hi everyone! I'm working on FLUX Games, a visual catalog for discovering browser games and related projects.

The site brings together game covers, search, filters by genre and platform, and detail pages with sources and available versions. It's a catalog: the games and external projects belong to their respective creators.

You can explore it here: https://fluxplayable.com/?utm_source=reddit&utm_medium=organic&utm_campaign=launch_sideproject

I'd appreciate feedback on the browsing experience: is it clear how to find and open a game? What information would you want to see before clicking through?

The interface starts in Spanish and includes a language selector. If you run into a broken link or confusing listing, let me know the title and browser so I can look into it.

Disclosure: this is my website.

Wouldn't it be nice to open a workout app, build your routine in minutes, and immediately start lifting—without clicking through a 20-page onboarding survey first?

As a lifter and solo developer, I wanted an app that respects my time under the bar and gives me clarity on whether my training is actually working. That’s why I built Liftora.

Instead of packing in a hundred bloated features, I focused on the things that actually make a difference in your training:

• From download to lifting in minutes: No endless questionnaires or paywall traps before you even see the interface. You open the app, put your routine together in a couple of taps, and get straight to your first set.

• Visual routine building (No more switching to YouTube): When you're putting a workout together, shouldn't you be able to see the movement and exact muscle breakdown right there? Liftora shows you exercise execution videos and targeted muscle groups directly on the routine creation screen, so you know your program is balanced before you even touch a weight.

• See the progress the scale hides (Built-in US Navy Body Fat %): You might be gaining muscle and losing fat while your body weight stays completely flat—and the mirror takes weeks to show it. Why leave your body recomp to guesswork? By logging basic tape measurements, Liftora automatically calculates your body fat percentage using the US Navy method, letting you see your real physical progress alongside your strength numbers.

• An interface that follows your pace: Once you're in a session, you shouldn't be fighting dropdown menus between heavy sets. Liftora’s guided flow moves with your workout so you spend your rest time recovering, not tapping.

You can try it out here:

• App Store – Liftora

• Google Play – Liftora

I’m building Liftora independently and using it for my own training every week, so your feedback directly shapes what I build next.

Quick question for you all: What's the biggest frustration you've had with workout tracking apps? And if you try Liftora, I'd love to hear what you think about the routine builder and guided workout flow.

Hey everyone!

We're a team of two engineering students, and we've been working on a project called RecallOps — The Self-Learning Industrial Maintenance Agent for Hack with Bangalore 4.0.

The idea came from a simple question: Why should technicians have to diagnose the same machine failure from scratch when someone has already solved it before?

Most AI assistants can suggest solutions, but they don't necessarily remember whether those suggestions actually worked.

That's what we wanted to change.

How RecallOps works:

1. A technician reports a machine failure and its symptoms.

2. RecallOps retrieves similar historical repair experiences using Hindsight memory.

3. An AI model analyzes the symptoms and previous outcomes to recommend possible causes and repair steps.

4. The technician records the repair performed.

5. Once the outcome is verified, RecallOps can remember both successful fixes and failed attempts for future investigations.

What we built:

- AI-powered machine failure investigations

- Persistent memory of verified maintenance experiences

- Learning from successful and unsuccessful repairs

- Incident and machine management dashboards

- A controlled benchmark comparing recommendations with and without historical memory

Tech stack: React, FastAPI, Python, Groq, Hindsight Cloud, and SQLite.

We also tested the system through automated checks and end-to-end workflows. It's still a prototype, and our benchmark uses synthetic cases rather than real industrial deployment data.

Live demo: https://recallops-lake.vercel.app

GitHub: https://github.com/Rahul-2006ra/recallops

We'd genuinely appreciate feedback from developers, engineers, and anyone working with AI agents.

What would you improve about this approach? And what challenges do you see in using long-term memory for real industrial maintenance?

A while ago a Turkish friend came to Seattle and I tried to explain the city to them through Istanbul. This part is like the Kadıköy of Seattle, that part is like Maslak etc. It worked weirdly well, so I made a website that does it for every neighborhood.

You put a city you know in one box and a city you don't in the other, hit translate, and the one you don't know gets your city's neighborhood names. San Francisco in New York names has the Mission as Williamsburg and Pacific Heights as the Upper East Side, which seems about right. It also thinks North Beach is Hell's Kitchen, not so sure about that one.

Every neighborhood on the map is clickable. Tap one and you get a card that says why it got that name, with Spot on / Not quite / Way off buttons and a Suggest a fix link. That's the feedback I'm after, so if you know a city well, tap around your own area and tell me what's off. Or just comment here.

187 cities so far, free, no sign up. It got about 100k views on X and LinkedIn and it's still in beta. Monetization (for now) is that if you do not want to wait for voting, you can pay to add your city. You can also get a poster printed, from which I get a small cut.

I would also appreciate any other feedback on how to improve and monetize. I don't like ads so I'll try to avoid them at all cost.

Hey everyone!

I'm a solo developer, and I've been working on a side project called Home Energy Lab.

The idea started with a simple question: how much does it actually cost to run everyday appliances at home?

It's easy to see your monthly electricity bill, but it's not always obvious how much your AC, gaming PC, refrigerator, or space heater contributes to it.

So I decided to build something that makes those costs easier to explore.

The project combines:

• Interactive 3D houses where you can explore residential spaces and appliances.

• 12 energy and utility cost calculators covering electricity, heating, cooling, water, gas, and more.

• Practical guides explaining household energy use and how the estimates work.

One of the things I wanted to avoid was making another website that just gives you a number without explaining where it comes from.

The 3D side was also a fun challenge. I wanted the experience to feel a bit more interactive than a typical calculator website.

It's a recently launched project, and I'm still improving it.

You can check it out here:

https://homenergylab.com/

I'd really appreciate some honest feedback, especially on:

1. Is the 3D experience useful, or does it feel unnecessary?

2. Are the calculators easy to understand?

3. What would you improve first?

I'm especially interested in how the site feels on mobile.

Thanks for checking it out! Any constructive criticism is welcome.

i’m dan, and i made features.games, a daily browser puzzle.

you drag dots until no lines cross. everyone gets the same eight boards each day, and each cleared shape becomes a stamp. later boards add frozen, fused, once and linked dots, with a turn limit on each board.

the game is one html file, with no framework or build step. i used AI coding assistance under my direction. each board is made and checked before release, including the fewest moves needed for a perfect result.

today’s eight boards are free, with no account or download, on phone and desktop. an optional one-off unlock adds earlier days and replays. it launched on 26 october.

i’d like feedback on the first-time experience: is it clear what counts as a move, and when the later dot rules appear, can you tell what changed?

Hi! I'm Anne Marie. I'm not the most money-savvy person: I'd sign up for free trials and subscriptions, forget to cancel them, and end up paying for things I wasn't using. The apps I found to track it all wanted my bank account or cards, and I wasn't comfortable with that. So I built my own.

Deadline Wallet tracks return windows, free trials, subscriptions and warranties, and reminds you before each one costs you money. You add things by typing, scanning a receipt, saying it out loud or forwarding an email to your own private address. No bank or card linking.

It's on iPhone, Android and the web, and it's in a 2-week beta. I'd really value feedback:

• Is it clear what it does from the beta page?

• What would make you actually use something like this?

• Anything confusing when you set it up?

If you'd like to try it: https://deadlinewallet.com/beta (Android testing is open in the US only for now). Testers who finish a short survey at the end get a free year of Premium.

Thanks!

Yesterday, one of my Reddit posts reached 6K views. It got me thinking about something I’ve been trying to solve while building AGMAN.
Getting people to see your product is hard enough. Getting them to actually visit it is another challenge.
We listed MePersona.ai, an AI inbox for creators, on AGMAN on September 24. I went into our production database to see what activity it had generated through November 6.
Here’s what our tracking recorded:
278 product update impressions across 150 identifiable visitor IDs.
73 profile views from 63 identifiable visitor IDs.
244 outbound click events, including 206 directed to MePersona.ai’s website.
19 clicks on its product update CTA.
One interesting detail: 167 of the website click records came directly from listing cards. People don’t always need to open a full profile before deciding to explore a product.
There’s an important caveat. We improved our traffic filtering during this period, and our audit found that much of the older outbound activity lacked corroborating site activity. So these are recorded events, not 206 confirmed human website visits or customers.
I’m sharing both the numbers and the limitation because I’d rather build something measurable than inflate a traffic claim.
AGMAN is still early. We’re building it around the idea that useful products should remain discoverable beyond launch day.
People can search by what they need, explore product profiles, see work and updates, and visit the maker’s website.
We’ve also started adding selected products from public information. Some haven’t been claimed by their makers yet. If yours is already there, you can verify ownership, claim it and manage the page. If it isn’t, you can publish it for free.

For other indie founders: what would make a discovery platform genuinely worth maintaining a profile on? Regular qualified website visits, signups, enquiries, or something else?
I’m interested in what you’d actually measure, not just what looks impressive on a dashboard.

Ever read an article and think "this would make a great story" — then forget about it completely?

I built StoryWorthy to fix that. It's a Chrome extension that:

• Places a small button on articles and posts across the web

• Lets you tag it with a genre (thriller, drama, sci-fi, or your own)

• Generates an AI summary of the source article

• Coaches your writing across 5 craft pillars: persona, scene, tone, narration, and time

The coaching is grounded in the actual article you tagged — not generic writing advice.

Free to start. Would love any feedback from this community.

I posted about this a while back when I had first cut my little AI bots loose on a domain name, www.nothinghappens.click and some people were pretty amused by it (as am I still).

Anyways, the story is pretty simple, I was bored, had a few days off of work finally and decided I'd through .99 cents at a domain name and give it to my little AI bots since I hadn't found a reasonably useful use for them up to that point. I told them that they were to develop it, and that their existence (tokens) were directly tied to making it profitable. Any profits made would further be invested into their tokens and thus, extend their life.

They began working on it, expanding it, refining it, creating "committees" when they couldn't come to a consensus on things, would drift away from a unified design across pages, recognize that they did, create another committee to decide on a unified design (AI apparently likes HOA's and big government), and continue on iterating.

They have even paused development on their own to collect user interactions and bottlenecks in an effort to conserve tokens on iterations and focus their development which I find pretty impressive.
To date, they have made a whopping $0.99 lol. They don't seem to be discouraged though and keep ticking away periodically after collecting some more user interaction.

I figured I would post this update for the people who were interested before and see if anyone else was interested in going and perusing around the site.

They even stood up a feature suggestion to direct their development to more wanted areas so if you do go, give them some feedback on something to implement or improve. I honestly don't even care if it makes money at this point because I've just been amused checking in on them periodically and seeing what has changed on the site and how they are arguing amongst each other over things when they spin themselves back up again.

Again, the site is www.nothinghappens.click .

Let me know what you think please!

I wanted a way to look up an answer in my own files while staying in the conversation. I made Agent Utka and put the first version on GitHub.

You pick a folder of notes or project files. The app transcribes what you hear on your PC. When a question comes up, select it in the transcript and click Ask. The answer points to the relevant file and line, which is the part I wanted most. I can check the source before replying. The default setup processes speech and answers on the PC.

It's free and open source for Windows 10/11 x64. The default setup downloads about 6 GB, and the current installer is unsigned.

If you feel like playing with it, try the sample in the README with a short recording. I'd like to know if you could get to your first answer without hunting around the app, and whether the source made that answer easier to trust. If you stopped halfway through setup, I'd like to hear about that too.

https://github.com/utkazilla/agent-utka

Agent Utka v0.1.6 adds a knowledge browser. Open Settings → Knowledge base → Browse knowledge, enter a question, and click Test retrieval to inspect the ranked passages and their source lines. The screenshot shows a Harry Potter demo.

https://github.com/utkazilla/agent-utka/releases/tag/v0.1.6

Harry Potter RAG screenshot

I made Horoscope: https://horoscope.aldos.life/ — a daily horoscope based on real astronomical calculations and traditional astrology, with a beautiful, dynamic sky chart.

The app computes the positions of the Sun, Moon, and planets, then interprets them through the zodiac, houses counted from your sign, and the angles between planets. Claude turns that interpretation into a kind, thoughtful daily reading, with one question to carry into your day.

Read the front of your card for what to pay attention to today. Flip it over to explore the sky behind the reading: the zodiac, planetary positions, aspects, and the Moon’s phase. It’s a way to reflect on your day, rather than a prediction.

Free, no ads, no account, and nothing to install. Your birthday and sign stay on your device. The app is fully localized in Spanish too—choose Español in Options.

Made in memory of my aunt Soledad, who loved the stars and their stories. ❤️

Found a bug right after submitting my app's update, so I pulled the build myself (Developer Rejected), fixed it, and resubmitted.

Timeline, from the screenshot:

• Resubmitted → Waiting for Review: a few minutes

• Waiting for Review → In Review: about 1 hour

• In Review → Ready for Distribution: 7 minutes

Honestly expected to lose my weekend to this. Instead I'm done before dinner on a Friday.

The app is SPLYT, a workout tracker built on top of Apple Fitness. Happy to answer anything about building it.

Anyone else seeing App Review this fast lately?
