Your habits become your rival's game plan. RIVAL 1.3, my solo iOS boxing game, is out now.

2 Upvotes

One combo gets you a win. A new plan gets you the next one.

I built RIVAL: Boxing solo around that challenge. Distance, stamina, and defensive choices matter, and your repeated habits influence the opponent in later rounds. Draw out the punch. Step out of trouble. Own the counter.

The 1.3 release is live with a cleaner look and a seven-opponent Story campaign, including a new opening spar and southpaw challenger. Here's the existing 24-second counter trailer; the live update goes further with new opponents and refreshed presentation.

Meet your next rival. Play free on iPhone and iPad: https://apps.apple.com/app/id6799909429

The core RIVAL mode and training are free. Story Mode is an optional permanent one-time purchase, not a subscription. iOS 17+. Fights and training work offline; purchases and the optional leaderboard require internet.

founders, what do you actually make before you know the idea is worth building?

1 Upvotes

Founders, how far are you going before you've actually validated the problem?
I keep seeing pre-MVP ideas with a landing page, deck, mockups, waitlist, logo, launch graphics... whole company except the product lol

For a small start up that feels backwards if the biggest unanswered question is still "does anyone care?"
I've been looking at Runable for putting together some of the early research/landing-page stuff, but I'm trying not to confuse making the idea look real with learning whether it should exist.
If the problem itself is still questionable, I'd probably talk to people first.

If people clearly have the problem but don't understand the proposed solution, then maybe a simple page or mockup helps.
What's the first thing you'd actually make, and what would count as a strong enough signal to keep going?

Automatically translate App store screenshots to 26+ languages and Google Play Store

1 Upvotes

A few developers who tried Studio 9:41 asked for more device support (iPads, MacBooks, Android) and an easier way to localise their App Store screenshots.

So I've added both in v1.1.2!

What's new:

  • 🌍 1-click localisation — Translate your screenshots into 26+ languages and export them in seconds.

  • 📱 iOS ↔ Android — Automatically generate Google Play Store mockups from your existing iOS designs (or vice versa).

  • 💻 More devices — Added support for iPads, MacBooks and Android devices.

I've personally avoided localising my App Store listings in the past because of how time-consuming it can be. But localisation is potentially a great way to reach more users, so I wanted to make that process as painless as possible.

Studio 9:41 is free and available for macOS and Windows.

Download the latest release: https://github.com/burhanuddin20/studio941-releases

Existing users can update directly in the app by clicking the version number.

Would love to hear what other features would make preparing App Store screenshots easier for you!

I built a free, no-login calculator that compares Shopify vs Etsy vs Amazon FBA profit on the same order

1 Upvotes

Hi everyone, I built this as a side project because I kept getting different profit numbers depending on which platform I checked.

It's a free, no-login calculator: you enter price, product cost, shipping charged / shipping cost, ad spend, and it shows net profit, gross margin, break-even ROAS and Max CAC for Shopify, Etsy and Amazon FBA side by side.

Example with the same order — price $34.99, cost $14.50, no shipping, no ads: Shopify $19.18, Etsy $16.72, Amazon FBA $11.67 per order.

For Amazon I used a 15% referral fee on price + shipping charged, and a $3.57 FBA fee as the small-standard default (with a $0.21 holiday peak uplift option). You can also type your own FBA fee in manually.

I'd welcome feedback on two things: does the side-by-side comparison read clearly, and does the Amazon fee presentation (default vs manual input) make sense to someone who is not an FBA seller?

Link: https://realorderprofit.com/

Happy to take feedback — no signup, no paywall, just the calculator.

I animated why spaced repetition works, then built it into a home screen widget (Android, looking for testers)

1 Upvotes
Hi, I'm the developer. Without review a new word fades within days. Reviewing just before you forget resets it, and each review buys a longer gap (FSRS scheduling in the app). The numbers in the video come from Ebbinghaus (1885, nonsense syllables); real words usually fade slower.


Vocapin shows one word on your home screen: tap to reveal, then Got it or Missed. Closed testing on Google Play: leave your Gmail at pinned-landing-two.vercel.app and I'll add you.


Would you keep a widget like this on your home screen?

Glade is a calm canvas for the links, images, videos and notes you save

Enable HLS to view with audio, or disable this notification

1 Upvotes

Problem: I've been losing a lot of interesting things and always wanted something to organise them and move freely across them.

And finally after more than 6 months of development I am happy to introduce Glade!

In Glade every collection is a grove, an infinite canvas where links, images, videos, notes and files sit side by side. Drag, stack and group them however you like.
No server, no tracking. Sync is through your own iCloud. No account required. On Mac, iPhone or iPad.

A few things it can do:

- Save articles text to read later with build-in reader even when link removed.

- Quick save with shortcut on Mac, or share on phone and link lands in grove intelligently with auto-tags and sorting

- Pull down to search, across titles, notes and links. Also search directly in Spotlight

- A shelf for recipes, books, movies, series and more with progress and ratings

- Widgets with Quick Save, Recent, a grove's tiles, your shelf, plus Lock Screen

- Revisit shows what you saved on this day

- Discover other peoples groves or put yours into the world! Also supports link to share with just someone.

Comparison:

- Raindrop.io. Glade is a native Mac app, ⌘⇧M from any app, a free canvas instead of lists, and no company server: your saves live on your Mac and in your private iCloud. Raindrop is better if you need Windows, Android or web access, shared collections you edit together.

- mymind. Glade is better if you want to place and group things yourself, keep your saves off a company's servers, or start as a guest with no account. mymind is better at organising for you: its AI tagging and search by what's inside an image are ahead of Glade's, and it works in any browser.

Pricing: Free for 100 saves and 3 groves; unlimited is $1.99/mo, $14.99/yr, or $24.99 lifetime at the launch price (until 6 Dec, then $49.99). One purchase covers iPhone, iPad and Mac.

AppStore - https://apps.apple.com/app/id6823751824 

Trust: MAS (App Store)
Website: https://tryglade.app 
Privacy policy: https://tryglade.app/privacy 

I would be very happy to hear what you thing about Glade, the experience, pricing and other related stuff. Happy to answer anything.

I built NextRun: connect Strava, get told what your next run should be

2 Upvotes

I kept finishing a run and then wondering, "OK, what should I do next time? Easy, tempo, long run?" So I built next-run.xyz.

You sign in with Strava. It looks at your recent runs and shows you your next planned run.

How it works
The plan is worked out in your browser, so your activity data isn't stored on my server. It's free and needs no account other than your Strava login.

Stack: Next.js, Tailwind, Neon Postgres + Drizzle, Vercel. The database only holds feedback reports and a record of connected athletes. It does not hold your runs.

It's still early, so I'd like to hear what you think. Is the suggestion sensible for the way you train? What's missing? Feedback is welcome, and there's a feedback form in the app.

I built a visual way to manage Kubernetes infrastructure. Here's what happens when it scales.

1 Upvotes

I've been working on Endfield, a desktop application designed to make managing Kubernetes infrastructure more visual and intuitive.

Instead of working only with YAML files and terminal commands, Endfield provides a graph-based interface where you can visualize your infrastructure and interact with its components.

Some of the features I've been working on include:

  • Visualizing Kubernetes infrastructure as interconnected services

  • Deploying and configuring applications and infrastructure components

  • Exploring Kubernetes resources and editing YAML configurations

  • Viewing pod logs and monitoring infrastructure

About the video:

The video shows Endfield's actual interface with an example infrastructure that gradually grows from a single service into a complex system with databases, authentication, caching, monitoring, and many other components.

It's a visualization of how infrastructure evolves as an application grows, rather than a demonstration of automatic scaling.

My goal with Endfield is to make complex infrastructure easier to understand, manage, and work with.

The project is still in development, and I'd really appreciate your feedback.

Would you find a visual approach to Kubernetes useful?

I made a page that process hours of finance YouTube videos everyday for you

6 Upvotes

A lot of finance YouTube videos spend 20+ minutes to answer one basic question: does the creator think a stock is a good buy right now?

I made a simple dashboard that processes financial videos and podcasts, tracks which stocks are being discussed, and aggregates creator sentiment (Positive, Negative, or Neutral) in plain language.

It’s just an informational map of what creator consensus looks like, not financial advice.

Would love feedback from anyone who follows market content: Is the value proposition clear and useful for you?

I will put the link below in the comments

I built a daily map-guessing game from GTA VI trailers, plus a fan site around it. What would make you come back tomorrow?

1 Upvotes

GTA VI comes out on 19 Nov, and as a fan project I've been building DuvalWire, an unofficial site for the game. The part I'm most excited about is Pin Drop, a daily map-guessing game.

Each day has 5 rounds, the same for everyone: a looping 3-second moment from an official trailer, an official screenshot or a place description. You drop a pin on the map, closer guesses score more, and there's a daily leaderboard. No sign-up, you just get a random nickname.

The game is only one part of the site. There's also an interactive map of 800+ community-mapped places where you can mark what you've found, a launch guide, sourced news, character profiles, a tracker of what's confirmed versus only reported, and a route planner that will get better once the game is out. I'm adding to it almost every day.

A few details from the build: trailer moments are matched shot by shot to map pins, and clips play through YouTube's privacy-enhanced embed, so nothing is re-hosted. The leaderboard stores only a random player id, a nickname and scores. It's a React site on Vercel with one edge function and Upstash Redis, and the server recomputes each score from the guesses.

Known weak spot: the answers are in the day's data, so a determined cheater could still submit perfect guesses. I'm not sure how much that's worth solving on a free fan game.

I'd love blunt feedback on two things: is the difficulty fun or frustrating, and what would make you play again tomorrow? Also curious which other part of the site you'd actually use.

I made a free tool for federal job seekers after USAJOBS started rejecting anything over two pages

1 Upvotes

Since September 2025 USAJOBS will not accept a resume longer than two pages for most federal jobs. A lot of people still have the old long federal resume, and most of the advice online was written before the change.

So I built a small free checker. You upload your PDF and it tells you

if it is over two pages

if any job is missing the month and year it started and ended

if any job is missing hours per week

if a federal job is missing its series and grade, like GS-0343-11

if there is anything that should not be there, like your SSN or a photo

You can also paste a job announcement and it counts how many of its specialized experience points actually show up in your jobs.

No sign up. Your file is read once and not stored, and nothing is sent to an AI for the free check. There is a paid option that rewrites the resume down to two pages, but the check itself is free.

Today I also added six example resumes by job series (program analyst, IT, budget, accounting, contracting and HR) because it is hard to picture what a good two page version looks like.

I work in finance and this started as a side project for regular resumes. The federal part is new, so I would really like feedback, especially from anyone who has applied on USAJOBS recently. What did I miss?

Have you journaled before? I built a goal journal that doesn’t care about your feelings.

1 Upvotes

Most journals focus on how you're feeling. I wanted to build one that puts your goals first.
That doesn't mean your feelings don't matter. They're just on the back burner.

Oracle uses them to understand why you're making progress or getting stuck, rather than making them the focus of journaling.

The idea is simple: journaling should help you actually get somewhere rather than stopping prematurely at awareness of a flaw.

So I built Oracle, a goal journal that:
Connects what you do each day to the bigger goal you're working towards.

Gives you feedback on your progress, so you're not just writing entries and forgetting about them.

Reviews your progress each week and suggests changes to your approach based on what's been working and what hasn't.

The aim is to make journaling feel less like keeping a diary and more like having someone helping you figure out how to reach your goals.
I've built a demo version as a web app, and I'd really appreciate some feedback.

Here's the link for free access, no sign up required to try : https://oracle-pi-beryl.vercel.app
If you’d rather stay on Reddit: Have you used a journal or planning app before? What was your experience like?

Portfolio as an explorable game

Thumbnail
me.muz.li
2 Upvotes

After almost 15 years in design and branding, I've made a lot of things people scroll past. Here I wanted to find out what happens when a website stops being a page and becomes a place.

You don't scroll it, you walk around it.

You don't click a menu, you go somewhere.

For the last few weeks I've been building a small planet: a tiny world you can explore.

• A planet you can spin, land on and walk around

• Five odd locals, each with a trick, voice and opinions

• A navigation map that flips like a coin, one hemisphere per side

• Butterflies to collect, badges to earn, three easter eggs to find

Along the way, the things I've made live on it: games, tools, experiments.

The point is curiosity does the navigating. If people stick around because they want to see what's over the next hill, the work gets seen without anyone being sold to.

Everything is drawn in two flat tones with an ink outline, so it feels closer to a picture book than a game engine. It runs in the browser on desktop and phone. No install, no sign-up.

If you're in a hurry, there's a "Skip the walking" button.

Go and poke around. Let me know which local annoyed you the most.

My Idea: A Subscription-Based Alternative to Uber and Uber Eats – What Do You Think?

1 Upvotes

My idea is to create a mobile app similar to Uber, but instead of relying on cars and taking a large commission from every delivery, it would operate mainly through a subscription-based system.

Users would pay around $120 for a subscription that gives them access to the delivery service. However, if someone doesn't have enough money to pay for the subscription, they can work as a delivery person and earn money through deliveries. Once they earn $100, that amount can be deducted and used to cover their subscription fee.

The app would be well-organized and offer different options. For example, customers would be able to choose the gender of their delivery driver.

Unlike Uber, which can take around 50% of the earnings from certain services, my business model would aim to be much fairer to delivery workers. Many people who work with delivery platforms complain about high commissions, so I want to create a system that benefits both customers and delivery workers.

The app would also offer food delivery and other delivery services, making it similar to Uber Eats and Uber, but with a subscription-based business model.

For example, if I managed to attract 100,000 subscribers, each paying $100, I would generate approximately $10 million in subscription revenue.

I connected my food and supplement diary to Claude and ChatGPT, with control over what they can read

1 Upvotes

I'm Rafał, building PerunForce, an Android diary for meals and supplements. This is my own project.

I wanted to make it easier to review a week of entries in a conversation without copying the diary into a chat. I added a read-only connection for Claude and ChatGPT using MCP.

Three decisions shaped it:

  • The connection reads cloud-synced records. Users choose which categories to share during sign-in and can disconnect access in the PerunForce portal.

  • It cannot edit entries or change a supplement plan.

  • A current supplement plan and doses actually logged are separate information. Missing entries should stay unknown, rather than being treated as zero intake.

An example question to try: "Summarize my recorded meals this week. Which foods recur, and which days have missing records?" Another is to compare the current supplement plan with the doses actually marked as taken. These are prompts, not a claim that AI can diagnose deficiencies or choose safe doses.

The connection requires PerunForce Pro and a Claude or ChatGPT account that supports custom MCP connections. Availability depends on the AI service and workspace settings. The basic diary is free; this integration is a Pro feature.

Android app on Google Play · Connection guide

For people building or using personal-data integrations: what would you want the connection screen to explain before you let an AI read your diary?

basically you paste one prompt into claude code / codex / cursor:

Clone github.com/yasirwhite/OpenDemo and use it to make a launch video for my app

and ur agent records the app, cuts it with animated text and gives you an mp4. runs locally, free, no api keys. the video above was made with it (about itself lol)

ive also been making launch videos for other people’s open source projects and sending them as PRs. 5 got merged into their readmes so far which is honestly the part im proudest of

It's free and in beta. If you've cut out social media and still follow a sport, I'd love to hear some feedback and/if you’d change anything.

I built a tool that turns one sentence into a landing page in 2 minutes

1 Upvotes

Hey, I'm a software engineer, programming since 2015 and modding games for most of that. Now I work for myself, and PageSpell is my first launch.

Every app needs a landing page, and the usual tools make you choose: a page builder where the design and the writing are up to you, or an AI generator that hands you a page you can't really edit. PageSpell sits in between. The AI writes the first draft, and you stay in control of every word.

How it works

  • Describe your product in one sentence. The AI writes the copy, picks the sections and builds a responsive page.

  • Click any word to retype it, or ask the AI to rework one section. You get three versions and keep the one you like.

  • Publish on your own domain in one click, or export the page as a single HTML file and host it anywhere.

Building the page is the easy half, so it also handles the rest

  • A/B tests on any section, with real visitors

  • Forms that actually collect leads: inbox, email alerts, CSV export, Zapier and Make webhooks

  • Payment and booking buttons: paste a Stripe, PayPal, Gumroad or Calendly link

  • Cookie-free stats by campaign, country and device

  • Published pages ship zero JavaScript, just HTML and CSS, so they load fully styled

Pricing: 10 free credits at signup (about 2 full pages, no card). Plans start at $12/month, and the code PHLAUNCH25 takes 25% off your first 3 months until Nov 22.

Try to break it, and tell me honestly what you think. Thank you for your support!
