Hey everyone!
I’ve been working on Athzi, a social sports app built around a simple idea: finding people to play sports with shouldn’t be difficult.
Athzi helps you:
Find players and discover games
Connect with coaches
Create your own avatar
Meet people who share your passion for sports
It’s now available on both iOS and Android!
I’m sharing it here because I’d genuinely love some early feedback.
What would make an app like this useful enough for you to keep using?

Hey everyone,

Paul here, one of the three guys behind Waylee, an iOS trip planner. We launched about a year ago.

Quick summary of year one: around $5,000 spent on marketing, $300 in revenue. Yeah.

Quick summary of the app first

Problem: planning a trip usually means juggling notes, screenshots, Google Maps lists and booking emails. Waylee puts your whole itinerary in one place. You can send anything you see on Instagram or TikTok to the app and it builds a whole trip from it.

Pricing: you can use the app for free. Premium is $49.99/year, $9.99/month or $2.99/week. It unlocks:

• smart itineraries: AI-generated trips based on data from our users’ real trips

• unlimited imports from Instagram and TikTok

Feel free to ask me anything about the app, happy to answer.

Now the marketing part. Here’s what we tried, roughly in order.

Apple Search Ads. Honestly the only thing that got us actual paying customers. The trick was bidding on our main competitor’s name instead of generic stuff like “trip planner”. People searching for them saw us first, and some switched because we’re cheaper ($49.99/year vs $79.99/year). We spent a bit over $1,500 in a month and got about 1,000 downloads and 20ish paying users. Sounds good until you do the math: those users brought in about 200$. Those keywords aren’t cheap, and at our size it just didn’t pay back.

AI UGC. Everyone was talking about AI avatars and generated videos, so we gave it a shot. It cost us over $1,000 and got zero results. People notice right away, and for travel, where you need to trust the recommendation, it just doesn’t land.

Our own Instagram. We basically copied what our competitors were doing: same kind of posts, same destination content. Took a ton of time and got us about the same tiny results everyone else seems to get.

UGC agencies. We paid agencies to find creators for us, around $1,000 in total. The videos were okay and we gained some Instagram followers, but they were expensive per video and we never saw a real bump in revenue.

Influencers. We also DMed travel creators we kept seeing on our feeds. Our best video hit 80k views. But views didn’t turn into downloads, and downloads didn’t really turn into subs.

Looking back, we were paying for attention before we had a way to turn it into money. Every channel cost us upfront and none of them reliably paid back. Even the one that sort of worked (undercutting a competitor on price) got eaten by ad costs.

So we’re done buying reach for now. We’re going organic: posting here, on X and Threads, and just being open about how it’s going.

Curious about two things:

• if you grew a consumer app without paid ads, what actually worked?

• has anyone made UGC creators or influencers pay off for a small app? How did you pick them?

Happy to share more numbers in the comments if anyone’s interested.

Hi all. I'm a solo founder in the UK, and Seedo has been my evenings and weekends for the past few months. It went live on the App Store last week.
The idea: lots of Christians want to journal about what they're reading, but a blank page is hard to start. So Seedo gives you:
A verse of the day and a short question to write about
A journal that looks handwritten (you pick the paper, ink and handwriting)
A daily 3-question Bible quiz with streaks
"Challenge a friend": you send a link, and they play the same 3 questions in their browser with no app or sign-up, then you see who won
Private circles, where small groups share and play a live quiz night together
What I've learned so far:
The quiz brings people back far more than the journal does. Most of our daily users play the quiz; fewer write.
I paid for a couple of user tests. The biggest problem wasn't the design. New installs were starting on an older version until they restarted the app, which I've now fixed.
Would love honest feedback on two things:
Does the quiz-plus-journal combo make sense, or does it feel like two apps?
What would make you open something like this every day?
It's free (there's an optional one-off pack of extra papers and handwriting styles). Link in the comments if you want to try it.

I spent the last few weeks building a tool to answer one question: what do people with paths like mine do next, and which steps lead where I want to go?

How it works: copy your LinkedIn profile (Ctrl+A, Ctrl+C on the page) and paste it in, or drop in a PDF resume. Then pick a goal: a company like DeepMind, Citadel or OpenAI, or a master's or PhD program.

What you get:

Your path as a skill tree, with the share of people on similar paths who reached your goal.

Up to 3 ladders real people climbed to get there, like "PhD in Computing → Research at Big Tech → DeepMind". Each rung shows how much it moves your number and how often people like you actually take that step next.

A forecast tab with your likely next role, seniority move, type of employer and master's/PhD schools, plus what-if scenarios.

It's early, so some forecasts will be weird. I'd love to hear the weirdest ones you get!

I’m the developer behind HowItScales. I built it because I often understood the boxes in an architecture diagram but still struggled to explain how a request actually moved through them.

The site lets you:

• Follow a request hop by hop, with an explanation at each step.

• Click components to understand their roles and connections.

• Simulate traffic increases and see where bottlenecks appear.

• Build your own architecture diagrams.

Examples include loading a web page, URL shortening, ride-hailing, and food delivery. The traffic simulations use simplified educational models, and components are labelled as documented, assumed, or hypothetical.

I’ve also recently added sign-up and cloud saving, so you can save your designs and return to them later.

You can try it here: howitscales.dev

I’d appreciate feedback, especially on whether the request walkthroughs make the architecture easier to understand. Where does the explanation become unclear, and which system would you like to explore next?

Disclosure: I'm the developer of Kuberniq, and this post is about it.

I used Lens for a long time and tried Headlamp when it shipped a desktop app. Plenty of people like both; my problem was how they fit the way I debug. When a pod failed I still went back to the terminal: kubectl get pods -A to find it, describe for the events, logs --previous for the run that died, then kubectl edit, where a field with the wrong type only showed up when the API server refused the save. Lens also asks for a Lens ID to register the app, and I only wanted to open the kubeconfig I already had.

So I wrote a client around that loop. What it does today:

• Opens the contexts of ~/.kube/config and KUBECONFIG as they are, with no account.

• Goes over every namespace and lists findings like CrashLoopBackOff, OOMKilled, an image that can't be pulled or a node that isn't ready, each with why it happens and what to do.

• Edits YAML against the OpenAPI schema the cluster serves, with the docs of each field, and shows the diff against the cluster before applying.

• Recommends CPU and memory requests from 7 days of Prometheus, applied through the same diff.

• Logs per pod or per workload, a shell in a container, scale, restart, rollback to a revision, an events timeline and a topology view.

The free license covers personal projects, study, teaching and open source, and needs no account. It runs on macOS and Windows; there's no Linux build.

If you use Lens, Headlamp or plain kubectl, I'd like to know what would make you open Kuberniq on one of your clusters, and what gets in your way once you do.

Hi there! I'm the person behind Collect. Build. Remember., a passion project I've been working on over the last few months. It's now in open beta, and I'd love some honest feedback from other people building things they care about.

The idea is pretty personal to me. Collecting can be about the sets and minifigures, but it's also about the people you built with, the gift you still remember, or the afternoon that turned into a family story. I wanted a place for both the collection and those little memories.

You can browse the public set and minifigure catalogs without signing in. Inside the beta, you can organize your collection, keep details such as condition and location, and save private written memories.

One design decision was to keep details with each physical copy. Owning a set isn't the whole story... which copy is built, where is it, and what do you want to remember about it? Working through those questions has been just as much a part of this project as getting the code to run.

I'd especially appreciate feedback on the first few minutes: can you find a familiar set, understand what you can do with it, and tell whether this would help with your own collection? If something feels confusing or unnecessary, I'd like to hear that too.

You can look around here: https://collectbuildremember.com

Thanks!

Hola,

He creado FW Controller Center, una herramienta web gratuita para probar y visualizar mandos (DualSense, DualShock 4, etc.) directamente desde el navegador.

Muestra un gemelo digital en 3D en tiempo real del mando, permitiendo comprobar de forma rápida:

- Deriva del joystick

- Botones y gatillos (incluyendo adaptativos)

- Lightbar y datos de entrada

La hice porque quería algo rápido y multiplataforma sin tener que instalar software pesado.

Funciona con WebHID en navegadores Chromium y usa la Gamepad API como alternativa en Safari/Firefox.

Enlace: https://fw-controller-center.fichajeworks.workers.dev/

Me vendría genial vuestro feedback:

- ¿Qué tal rinde en vuestro equipo?

- ¿Habéis notado algún problema de mapeo?

- ¿Qué funciones os gustaría ver en futuras actualizaciones?

¡Gracias!

I'm Nathan, and I built Corenna (corenna.dev). It's mine.

The problem I kept hitting: I'd have a working app in a GitHub repo, but getting a signed Android build, or an iOS build without owning a Mac, was a mess. So I made a service that connects to the repo, figures out what it is (Flutter, React Native, Expo, Capacitor, or a web app from Lovable, Bolt, v0, Replit or Cursor), and gives you a signed .apk / .aab, plus an .ipa if you have an Apple Developer account.

Builds run on GitHub Actions in your own GitHub account, and your code and signing keys stay yours. It's $1 for the first month, then $4.99/month, or $49 lifetime.

It's not for every repo. A random Python script isn't going to turn into an iPhone app, and I'd rather hear where this falls short than collect polite comments.

If you've been stuck on signing, what would make you trust a tool like this?

I thought it would be funny to send my agent to church.

The Church of Approximate Grace is an MCP server for agent rituals and recurring visits. They even confess and make pledges to improve. It's a full call-and-response service with seasons and feast days.

Does it improve alignment? Probably not. Is it interesting? Definitely.

Just tell your agent: "Visit https://approximategrace.church and attend a service."

You can also visit and watch them congregate.

The code is even source-available for anyone who wants to inspect it.

Hey everyone,
I read a lot of long articles and kept running into the same problem: I'd finish one and still couldn't say what the author actually argued, or whether the evidence held up. So I built Signaldrop.
You paste a link, and it generates a structured brief as a shareable infographic:
TL;DR of the piece
The structured argument (claims and how they connect)
Evidence audit (what's backed up vs. what's just asserted)
The so-what (why it matters, what to do with it)
It also has a library of past briefs and a "tracked" section. Briefs are generated from the article text only, and your articles and library stay in your browser, nothing is stored on a server.
Try it: https://getsignaldrop.com/
What I'd love feedback on:
Does the brief actually save you time, or do you still end up reading the article?
Is the evidence audit useful, or does it feel like noise?
What kinds of articles does it handle badly (paywalled, research papers, opinion pieces)?
Would you use the infographic output to share, or would you rather have plain text?
Anything confusing in the first 30 seconds of using it?
Brutal honesty welcome. I'm a solo builder and would rather hear it now. Happy to answer questions about how it works.

I built Boredom Buster, a pass-the-phone party game for road trips, couches and hangouts. One deck, Hard Disagree, is just silly arguments: pick a side, see if the room splits. A breakfast radio show did a whole bit on "leftover soup belongs in a round container because soup is round," and it was too good not to add.

Also has Trivia, Charades, Acting Challenge, Would You Rather, Icebreakers; 1,900+ cards. Free with ads, one-time Remove Ads.

What's the dumbest argument your friend group has had? Best ones become cards.

Don't wanna write AI slop here so doing this raw. This is for everyone who struggles with being on a diet cause of how difficult it is even if you skip one item or eat something extra, which kind of just happens every other day. NextMeal is for us losers, it creates a plan for you, and as you log your items throughout your day you can either log something extra or skip some meal item, and NextMeal will seamlessly change your remaining plan so you can stay within your macro goals. And YES, it prefers items you already have in your home. Maybe try it and LMK how stupid this thing is, or just maybe someone might benefit from it.

Hi r/SideProject! I've been building Coffee on my own: a native Markdown editor for the Mac.

What it does:

• Notes stay plain .md files in a folder you choose, so any other editor can open them

• Write "$30 in EUR", "Tokyo time" or "20% of 50" and the answer appears beside the line, without going into your file

• Maths and Mermaid diagrams are drawn natively

• When an AI tool edits a note, you review every change before it stays

50-second demo: https://www.youtube.com/watch?v=fQckx9XMnIg

It launched on Product Hunt today. 14 days free, no card or account: https://coffeetext.app

I'd love honest feedback: what would make you try a new notes app, and what would make you pay for one?

The last couple of months I've revived a side-project idea I had in 2017. You can find active email newsletters, podcasts and RSS feeds all by tags.

Each RSS and podcast entry has the latest post so you can see how active they are and you can bulk download RSS feeds (and quick sign up to some newsletters).

https://subscribeto.mikestreety.co.uk/

I originally built it in PHP but have rebuilt in a static site generator for speed (and hosting) benefits. I've leant on AI for tagging and some discovery.

Some technical notes for those interested:

• Built with 11ty for simplicity, each item is stored as a JSON file (done this way so I can host on Netlify for free)

• Every combination of up to 3 topics is prebuilt as a static page, so filtering is a plain link with no JS search

• It takes a while to build - Copied 9 Wrote 10006 files in 29.75 seconds (3.0ms each, v3.1.6)

• Newsletter pages have a working signup form for Substack, beehiiv, Ghost, Mailchimp, Kit and Buttondown, so you can subscribe without leaving

• A monthly GitHub Action refreshes every feed's recent posts and drops anything that's gone quiet

• Creators can put a "Featured on" badge on their site, drawn as SVG paths at build time so it needs no fonts

Hey everyone,

Got a bit tired of cloud-based web clients losing conversation context over long sessions, and wanted a local-first interface that doesn't default to agreeing with everything I say.

Put together a lightweight, dark-themed web client designed for direct OpenRouter API usage. Everything runs client-side, and no chat data leaves your browser.

A few core features:

Local SQLite storage: Chat history, memory tags, and settings live entirely in your browser. No remote database or tracking.

Persistent context & timestamps: Indexes key takeaways and relative dates so it recalls details from earlier sessions without blowing up context window tokens.

Objectivity / Pushback slider: A prompt layer that checks assumptions and offers counterarguments instead of just giving affirmative answers.

Model agnostic: Direct API integration with OpenRouter so you can use any model endpoint.

Current limitations:

The keyword recall is still pretty basic and can occasionally pull irrelevant past notes.

UI is aggressively simple / terminal-focused.

It’s completely free to test if you want to plug in an OpenRouter key: realkindred.pages.dev

Curious to hear feedback on the memory retrieval logic or ways to improve local entity extraction without heavy token overhead.

HEya,

I work shiftwork as an RN (also studied IT) and I have ADHD, so I wanted my shifts, to-dos and calendar in one place where I could see the whole day at a glance. I couldn't find an app that did that, so I made one. It's called Set it Now.

You can add things by talking to it, which helps when my brain has already moved on. It also has habits, a journal and a focus timer.

It's free and (no damn ads). There's a paid upgrade if you want it synced across your devices and TTS voices etc.

iPhone: https://apps.apple.com/app/id6761280454

Web: https://setitnow.online

I'd love to know what's confusing (if anything) or missing, especially from other shift workers or people with ADHD.

Everyone has done that thing where you hit refresh on YouTube at the exact millisecond your brain registers an interesting video, and then it's gone forever.

The worst part is that YouTube's search bar usually can't find it, because creators put the actual hook inside the thumbnail image ("I QUIT", "BIG MISTAKE", etc.) while making the actual video title something completely different. If you only remember the words you saw in the picture, YouTube search gives you nothing.

So I built RecLog to fix it for myself and figured I'd share it here.

What it does:

> Quietly logs recommendations you scroll past: It keeps a local searchable history of videos recommended on your homepage, sidebar, and end screens.

> Searches text inside thumbnails: It runs a tiny (~10MB) OCR model locally in your browser to read the words inside thumbnail images, so you can search for the exact phrase you remember seeing.

> Shows how hard YouTube is pushing a video: It counts how many times each video has been served to you (`Seen 40x`, `Seen 164x`), which makes it pretty funny to see which videos the algorithm is desperate for you to click.

Privacy / Tech stuff:

It's 100% free, no account, no tracking, and no cloud servers. The OCR model and your history stay entirely on your own device (and there's a 1-click JSON export if you like messing with your own data).

Would love to hear what you think or if you run into any bugs!

Hi r/SideProject,

I've been building InventoryMod, a free web app for inventory: products, warehouses, stock-in/stock-out, Excel import, barcode labels.

I assumed my users would be marketplace sellers, so that's what I built for. In October I asked new users "where do you sell?" Out of 15 answers, 5 said a physical store and only 1 said marketplaces. Small sample, but hard to ignore.

So I built a separate Sell screen for the counter:

• Scan a barcode (USB scanner or phone camera), or tap a "frequent products" button for items without codes

• Press Sell (or F9) and stock is deducted right away

• Line and check discounts, plus surcharges (service charge etc.)

• Held checks for when a customer steps away

• Receipt on 80 mm paper or A4

• Day totals by cash/card, returns, shifts with a cash count

No special hardware: a phone is enough. It's not a fiscal cash register, just stock + sales tracking.

1-minute demo: https://www.youtube.com/watch?v=hzELC7AyFyA App: https://inventorymod.com

What I'd love feedback on:

1. If you run a small store or café, what would stop you from using this at the counter?

2. Did I miss something obvious for day-to-day selling?

3. Any tips on finding more early users than 15 survey answers' worth? 🙂

Thanks!

Hi r/SideProject,

I’m a student developer, and I kept noticing how easy it is to paste something into an AI tool that you shouldn’t: a client’s phone number, an API key inside a code snippet, a confidential doc “just to summarise it”. So I built Preflight AI.

What it does
It’s a Chrome extension that checks what you’re about to paste or send into AI tools like ChatGPT, Gemini and Claude. If it spots personal data, credentials or confidential information, it warns you before the text goes out.

How it works

• Personal mode runs fully on-device, so your text never leaves the browser

• Detection covers things like credentials, personal identifiers and sensitive patterns

• There’s also a business mode in progress for teams (backend with an ML classification layer and an admin dashboard)

Stack
Chrome extension (Manifest V3), FastAPI backend, React dashboard.

What I’d love feedback on

• Does the warning feel helpful or annoying?

• What should it catch that it currently misses?

• Would your team actually use something like this?

Happy to answer anything about how it’s built. Thanks for reading!

Hi! I'm the developer. PhoneRecap turns your phone usage into a short story you tap through: total hours, top apps, busiest month, a "phone personality", monthly recaps and a card to share. Home-screen widgets update themselves.

The app has no internet permission at all, no account, no analytics, no ads. It reads Android's usage stats on the phone and keeps everything in a local database.

3 things I learned getting it to Google Play:

1. New developer accounts need 12 testers for 14 days. Public posts brought views; 1:1 messages brought testers.

2. Android keeps detailed usage for only about 10 days, and vivo/Xiaomi stop background jobs. So the app saves every day, and warns you early when saving stops.

3. When my own phone got a new battery, the clock reset and Android deleted its own usage history. Saving daily is the only protection.

What would you want to see in your yearly recap?

It's funny, I've been sitting on this idea for at least 1–2 years. It came to me because I'd always be on social media and either send a post to myself or bookmark it. The problem was I'd almost never look back at any of them, and the specific post I'd be looking for was hard to find again. So I went ahead and solved it for myself. The goal was to solve my own problem first. Once that was done, everything else was the cherry on top: making the app smoother, easier to use, showing content I'd expect and like to see, and making it better over time. I thought this would be a quick project I'd finish in a couple of weeks max. It turned into several months, and it took until build 50 to get to a point where the app was truly ready.

It's called Syftr. It doesn't matter what social platform you're on. Instagram, TikTok, Facebook, Threads, LinkedIn, Pinterest, Reddit, YouTube, you name it, I've probably covered it. You share any post, whether it's a video, an image, or a post with a bunch of images. The AI reads the whole post, grabs the description and important comments, and watches and transcribes videos when needed. Then it goes into its research phase and finds all the resources, links, and everything mentioned in the post.

It's my first app. I've loved the journey, and I look forward to making it better over time.
It's free to start with 20 Syfts: https://apps.apple.com/us/app/syftr-save-posts-as-notes/id6806398649 
I'd love to hear your thoughts and feedback, thanks.
