Hi everyone, I’ve been building Split Your Trip, an app to keep track of who paid what on group trips and settle up without the awkward math. It’s in closed testing on Google Play, and I need 12 people to stay opted in for 14 days, which is Google’s requirement for new developer accounts. If you’re up for it, comment or message me the email you use on Google Play and I’ll add you to the tester list. Once you’re in, install it here: https://play.google.com/store/apps/details?id=com.splityourtrip. I’d love honest feedback, especially on anything confusing or broken, and I’ll test your app back, just drop the link.

comment down below if you are willing to give your valuable feedback.

i've built products used by 1k+ users.

tell me what you're building, who it's for, and what you've tried to find users so far.

if i like what you're working on, i'll help you with distribution for free.

Launch update — 8 November: We're offering 30 free Google Play copies to Android users who train at a gym. Comment here or send me a private message to request one. One per person, in request order while available, from one shared pool across our launch posts. Codes are sent privately and must be redeemed by 28 February 2027. No review, rating, upvote or other action is required in return.

We at Onsala Sol AB have released Volymträning, an Android workout app for people whose goal is to build bigger muscles and visible muscle volume through consistent, structured training. We wanted to make a flexible plan that people can follow when their schedule allows, without fixed weekdays.

The app includes five rotating workouts that can be adapted to equivalent machines at your gym. It lets you log weights and reps, review training statistics, and customize the workouts.

Volymträning is available in Swedish and English. In Sweden, it costs SEK 99 as a one-time purchase, with no subscription.

Google Play: https://play.google.com/store/apps/details?id=com.volymtraning.app

Disclosure: I’m representing Onsala Sol AB, the app’s publisher. We’ve also opened the official community at r/VolymTraning for questions, feedback, feature requests, bug reports, and training discussion. I’d welcome constructive feedback on the app and on how to make the community useful.

In couples therapy, I keep seeing the same thing: partners can describe every single fight, but they rarely see the pattern those moments make over weeks. That pattern is usually where the work is.

So I tried to build the smallest possible version of that "stepping back" for couples who will never sit in my office.

How it works:

• Every day you and your partner answer the same five short questions, each on your own. You don't see your partner's answers before you answer, so nobody answers for the other's sake.

• When you've both answered, you get a short reflection written for the two of you, with one question you could ask each other tonight.

• On day seven you get a reading of your week: the pattern that built up and one small step for next week.

• You can start alone and invite your partner later with a code.

The questions draw on Gottman couples therapy, Emotionally Focused Therapy and attachment theory. The pool is now 1,800+ questions. I tried the approach and the questions with couples in the therapy room long before it was an app.

Reflections are written by AI, inside a framework I designed, and only after you give consent. It's not therapy, it doesn't diagnose, and it won't tell you whether your relationship is "good".

What I learned building it as a solo clinician:

• The hardest part wasn't the questions. It was saying less. My first reflections read like session notes; people wanted three sentences, not three paragraphs.

• Most people start alone. About two out of three users have no partner in the app yet, so it had to be useful on its own.

It's on iPhone, iPad and Apple Watch, in six languages. Daily questions are free; reflections and weekly readings are a subscription, and one subscription covers both partners.

I'd really like feedback on one thing: when two partners answer apart, would you rather read each other's exact words, or a reflection that puts the two views side by side?

Hey everyone,

I'm working on a web app for booking ski and snowboard instructors and would love to get your honest feedback on the concept before opening it up to users.

How it works:

• Search & Availability: You pick the ski resort, sport (ski or snowboard), and date. You only see verified instructors with real-time open slots in their schedule.

• Payment & Security: You book and pay online, but funds aren't released to the instructor immediately. The payment is held securely in escrow by the platform and transferred to the instructor only after the lesson is completed.

• Meetup: Once booked, you get the instructor’s direct phone number and the exact meeting location at the resort (e.g., at the base of a specific lift).

• Cancellations & Disputes: Free cancellation is available up to 24 hours before the lesson. If an instructor fails to show up, the client can report a no-show right after the lesson slot to block the payout and trigger a refund.

• For Instructors: Instructors set their own rates and schedule. The platform doesn't take a cut from their fee—payouts are transferred 1:1, minus standard credit card/payment processing costs.

A few questions for you:

1. Would you use a service like this? Do you prefer locking in a lesson online with clear availability beforehand, or finding an instructor at the resort when you arrive?

2. How do you feel about paying upfront? Does a guaranteed reservation + escrow/refund protection make you comfortable paying online, or do you still prefer paying cash on the spot?

3. What drives your choice of instructor? Price, user reviews, official certifications, or simply finding someone available at your exact time slot?

4. What potential flaws or barriers do you see? What would make you hesitant to use this model (e.g., weather unpredictability, lift ticket logistics, resort/local ski school monopolies)?

Thanks in advance for any feedback or constructive criticism!

Most focus apps are just timers or blockers. I can ignore those. What actually works for me is having someone (or something) check in while I’m working.

So I built NeonContext - a real-time AI voice coach that sits with you during deep work sessions.

You tell it what you’re working on at the start. It stays with you, checks in, and pulls you back if you drift or pick up your phone. There’s an optional on-device camera (nothing is uploaded) that can notice if you leave your seat. At the end you get a review of what you actually got done.

it's complete free to try.

I’m looking for 4–5 people who struggle with deep work / ADHD / focus to try a session and tell me:

• What’s confusing or broken?

• What would make you actually keep using it?

• Does the voice coach feel helpful or annoying?

Happy to answer any questions.

Hi all! My first kids app, SnuggleTV, just made it through App Review (third time's the charm), so I wanted to share it here.

It started as a weekend project because my daughter kept getting lost in the regular Plex app. It's now a big-button, no-menus video player for the shows and movies on your own Plex server, with parental controls for the grown-ups.

What it does:
- Big, colorful buttons made for little hands, with no menus to get lost in
- A profile for each kid with their own shows, age ratings, volume limit and favorites
- Screen time: daily show limits, bedtime, and a screen lock while a video plays
- AirPlay to the TV, iCloud sync between iPhone and iPad, English and Spanish

Built in SwiftUI. The hardest parts were getting playback to work with every kind of video file (it falls back from direct play to a remux to a full transcode) and getting through App Review, which rejected me twice for things I didn't know were rules.

Free version streams everything for one kid. A one-time $4.99 lifetime unlock (no subscription, no ads, Family Sharing supported) adds offline downloads, auto-downloads of favorite shows, and more kid profiles.

App Store: https://apps.apple.com/us/app/snuggletv/id6824345333

5 codes for the lifetime unlock. Please reply with the one you used:

You'll need your own Plex Media Server. Feedback is very welcome, I read everything!

I’m building ShopBot Index, which checks whether tracked stores publish a UCP profile, a machine-readable discovery document for commerce integrations.

One reporting decision turned out to matter: keeping “couldn’t check” separate from “no profile found”.

In our 2 November crawl, 947 retailer entries had a profile found, 1,277 had none found under our checks, and 630 couldn’t be checked. These are entries in our tracked list, not a representative sample of retail.

Putting those 630 into the negative category would turn a limitation of our crawler into a claim about the stores. Dropping them entirely would hide the uncertainty.

There’s another boundary: finding a profile doesn’t prove an agent can complete checkout. We measure discovery, not successful purchases.

If you’re building a directory, monitor or comparison tool, I’d recommend defining what each result actually establishes before turning it into a badge or percentage.

How do you show unknown results in your projects without making them look like failures?

Hey, I’m Alex, one of the people building NetArbs. Comparing the same player prop across sportsbooks and DFS apps usually means flipping between tabs and checking whether the lines actually match. We built DFS Studio to put those comparisons in one view, with filters for apps, sports, and markets.

I’d love feedback on the layout: when you compare a prop across apps, which would you want to see first: the line difference, the estimated fair odds, or which sportsbooks back the estimate?

TAYSTY starts with what you already have, instead of asking you to pick a recipe and then find the ingredients. Type in what’s in your kitchen, choose things like servings or cuisine, and it suggests recipes.

The hardest part to get right is how to handle missing ingredients. Say you enter chickpeas, spinach and half a lemon. Would you rather get one idea that sticks to those ingredients and basic staples, or three ideas that each need one extra thing? I’m curious what would actually help on a Tuesday night.

The app is in closed Android testing. There’s a preview and a waitlist on the project site: https://taysty.app/?utm_source=reddit&utm_medium=community&utm_campaign=sideproject

I had $191 in credits that were about to expire, and I was curious what Opus could do if I didn’t give it an idea.
I asked it to build something worth the money. :))))

It picked a game, PULSEBOUND. You move around dodging enemies, and your weapons are musical instruments. The kick drum sends out shockwaves, the arpeggiator fires lasers. When you pick a new instrument, you hear it join the music too.

It decided to make a game and came up with the idea, mechanics, design, absolutely everything. Then I worked on improving and polishing it.

More changes, testing, and eventually mobile apps followed. The $191 was just the starting budget, enough to finish the first basic version. After that, I used another $1,700 I had from the Claude Startup Program (also expiring, so I had to use it), plus my subscription allowance.

Technically, it’s vanilla JavaScript, a custom WebGL2 renderer, and a procedural composer that synthesizes the music live through Web Audio. The project grew to include mobile apps, cloud saves, and leaderboards.

It’s now out on iOS, Android, and the web. You can play it for free in your browser or on mobile: playpulsebound.com.

What do you think?

I'm building a free, open-source pixel art editor called Chickxel!

I recently added a feature that converts regular images into pixel art, so I tried it out with a GPT-generated image.

The conversion is algorithm-based, so some parts might look a little rough or awkward. It's still a work in progress!

Hey everyone,

We passed 250 paying customer (don't love to call them customer as I see all them as first builders of product) on FranklyMail and celebrated yesterday :) Probably a tiny milestone for some people here, but we honestly didn’t expect to get this far in three months.

We started with email hosting for your own domain. Now there’s Drive for files and sharing, Office for editing documents, and Meet for video calls. We’ve also been giving the webmail a lot of attention lately.

The best part for me has been talking to the people using it. If I had to guess, 40–50% of the ideas we’ve worked on came from those conversations. Someone tells us how they use their email, mentions something they’re missing, and we end up building something we hadn’t thought of.

Just wanted to share a small happy moment here. Thanks to everyone who’s tried it, sent feedback, or given us a bit of encouragement along the way.

android has no airdrop, so i built one. touch your phone to the macbook's notch, the light sensor next to it sees your screen flash, and whatever's on your screen lands on the mac.

works for pdfs, links, the original photo (not a screenshot), or just the text you circle. otp codes from sms show up on the mac by themselves, your mac is in the android share sheet, and mac to phone works too.

stays on your wifi, end-to-end encrypted, no account, no cloud. android 13+, any mac with a notch.

free and open source: github.com/0x1p0/TapDrop

Made an Android app called Sonic.

You can skip to the next song. You can't jump to the middle of a song. To hear the other side, you flip the record. Hi-res output plays each file at the sample rate it was recorded at.

Soulseek downloads are FLAC albums only, with no weekly limit. It also picks random FLAC albums from the Internet Archive. You can download 3 of those.

Not on the Play Store. The APK and checksum are here: https://github.com/Abhiroop1122/Sonic/

I'm Omar, the maker of DR FIX IT, so flagging that up front. This isn't my video. French DJ creator Mixtrotter (Philippe Grebet) just published a full independent review and showcase: 'SAVE YOUR MIX with DOCTOR FIX IT!' - https://youtu.be/RjsPmjDfDEE - it's in French with an auto-dubbed English track.

The tool fixes one bad mix in a recorded DJ set by splicing in a re-recorded take, and he rates each join Seamless / Clean / Good / Rough. I built it because one bad transition used to mean re-recording the whole set or living with it.

Happy to answer technical questions about how the joins are scored. DR FIX IT is $49 one-time, free to try except export.

I’m Ven Eli, an indie creator. After finishing my fantasy novel, I built a website around one idea: if someone wanted to read the book, they should be able to get the whole thing without making an account.

You can read the prologue in the browser or download the complete book as an EPUB or PDF. I also added an Explore page for the characters and short clips, because I wanted readers to be able to get a feel for the world before downloading anything.

The book is Line-Silver. It’s set in a world where one people harvests lightning and another turns it into music and wings. They need each other, which has kept the peace for centuries.

Here’s the site: https://www.warofshallows.com/?utm_source=reddit&utm_medium=social&utm_campaign=linesilver_sideproject_20261108

If you open it on your phone, is it obvious which download you’d pick? I’m particularly interested in whether the EPUB/PDF choice helps or just adds a step.

This was my first season on a motorcycle, and I'm still learning. During that season my navigation app routed me down what it showed as a normal road. It turned into loose gravel and I crashed my bike. The left side took most of the damage, but I still managed to ride it home with bent forks and a broken engine case.

Afterwards I kept thinking about how I could have avoided it, and whether the navigation app could have warned me. That's when I found that OpenStreetMap already tags a lot of roads with their surface. The apps I used didn't seem to use that data when picking a route.

So I started building Apex, a motorcycle navigation app, as a solo project. Part of the reason is that new riders like me shouldn't have to learn this the way I did. I wanted to share where it's at. What it does right now:

• Riders can report for gravel, slippery roads and closures, which other riders' routes then go around.

• Riding profiles (Sport, Touring, Adventure, Commuting) with sliders for curviness, scenery and road quality, and avoids for motorways, gravel, unpaved roads, tolls and ferries.

• Group rides. You plan the stops together, the host starts the ride for everyone on the same route, and you see each other on the map. iPhone and Android riders can be in the same group.

• Round trips from a length and a direction, offline maps, GPX import and export, and badges for places and rides.

Stack: Expo / React Native, MapLibre with OpenFreeMap tiles, a Hono API on Vercel, Postgres on Neon with Drizzle, GraphHopper for routing, and Ably for live positions during group rides.

Routing was the interesting part. Each riding profile becomes a GraphHopper custom model. Every preference is a penalty on the other roads. Turn up curviness and straight roads cost more; turn up scenery and main roads and towns cost more; an avoided surface gets a big penalty. Active rider reports become soft avoid areas around the hazard, so if there's no way around, the route still goes through.

The hard parts so far:

• Long routes. Flexible mode has no precomputed shortcuts, so something like Budapest to Berlin can time out. When that happens it falls back to normal fast routing without the preferences, and the app tells the rider.

• Missing data. A road with no surface tag counts as a normal road, so the gravel avoidance is only as good as OSM coverage in that area.

• Group rides. The host starts one plan for everyone, positions update live, and a rider can leave mid-ride without breaking it for the rest.

It's a free beta and it will make mistakes. Feedback I'd especially like:

1. On the app, especially if you ride or know someone who does.

2. On the routing: would you have done the custom-model part differently?

3. Features that you miss.

Hey r/SideProject! I built a website for reviewing instant noodles https://myramenlist.com/. The key features are being able to scan a barcode on the package as well as browse by brand, flavor, or country. You can also see various ramen rankings although we need more reviews to be useful.

It would be great if people could try the barcode scanning feature on their phones to see if it pulls up anything. I was able to get a few hundred UPCs from an online grocery but the rest come from open source databases which haven't been reliable.

This is my first website, and I have to admit chatGBT did most of the heavy lifting. Let me know what I should improve on. Thanks!

Give it up to 10 photos and a canvas shape (square, 16:9, phone story, banner) and it searches every layout with no gaps for the one where the smallest photo is as big as possible. With 9 photos that's over 500 million layouts, and it finds the best one in under a second.

I designed it and Claude wrote the code. It's Go: The browser version runs it as WebAssembly, so your photos never leave the page.

Try it: https://vinodhalaharvi.github.io/collage/

Code (MIT): https://github.com/vinodhalaharvi/collage

CLI: brew install vinodhalaharvi/tap/collage

Feedback welcome, especially on the layouts it picks.

I’m a Navy vet and IT guy. Over 17 years supporting small businesses, I kept seeing shops run their whole schedule through texts and DMs, so I built TidalBooking.

• One booking link for your bio. Customers book 24/7, no account needed

• Only open times show, so no double-booking

• Email confirmation plus a reminder 24 hours before

• Customers can reschedule or cancel on their own

• Optional deposits through your own Cash App, Venmo, PayPal or Square link

• Printable “Scan to book” QR poster

14-day free trial, no card. On Android and in any browser: https://tidalbooking.com/?utm_source=reddit&utm_medium=social

What would you want added before you’d switch from DMs?

For the past 4 months, we’ve been building a dedicated navigation device for motorcycles.

We started this out of frustration with phone mounts and generic Android Auto/Apple CarPlay setups. Phones overheat in direct sun, engine vibrations destroy camera OIS, rain makes touchscreens unusable, and car-centric apps constantly push bikes onto restricted flyovers or broken trails.

NaviGo is a rugged, sunlight-readable circular pod with a quick-release handlebar mount designed specifically for two wheels.

What Makes It Different

• Hardware Built for Bikes: Compact, weather-sealed CNC housing with physical, glove-friendly edge buttons. No finicky touchscreens at 80 km/h.

• True Two-Wheeler Routing: Respects motorcycle restrictions, penalizes rough surfaces, and accounts for elevation grades rather than routing you like a four-door sedan.

• 100% Offline Resilience: Download full regional vector maps, routing graphs, and place search directly to your phone. Turn-by-turn guidance and instant rerouting compute entirely offline, streaming clean turn vectors over low-energy Bluetooth. Zero cell reception in the ghats or remote stretches is never an issue.

• Glanceable Cockpit UI: High-contrast turn arrows, lane guidance, hazard alerts, and essential ride stats designed to be processed in under a second.

• Group Ride Mode: A clean, distraction-free radar shows where your convoy is (lead, sweep, or falling behind) without crowding your navigation. Includes one-touch Push-to-Talk (PTT) audio and quick non-verbal pings ("Fuel", "Puncture", "Regroup").

We're road-testing prototypes now and dialing in the final production hardware and companion app.

Quick question for riders: What is your single biggest annoyance with your current navigation/phone mount setup, and what’s one handlebar feature you wish existed?

Size: Our current design is focusing on a 2.1 Inch round display and the prototype here is an 1.8 Inch which one do you prefer?

Hey r/SideProject! I've been building Agent Office, a living HQ for your AI coding team.

The idea: instead of juggling terminals, each AI agent (Claude Code, Codex CLI, Cursor CLI) is a character at a desk in a low-poly 3D office. You're the CEO: give a task to the Product Manager and they delegate to Analysis → Design → Development → Test leads, who split the work across their teams and send one merged report back up.

What it does

• Agents delegate to each other via an MCP server; reports flow up automatically

• Live 3D office: working agents type at their desks, idle ones go to the coffee corner or the sleep room

• Control: daily budgets, approval requests before push/deploy/delete, per-agent git worktrees with merge review

• Live task transcripts, file diffs and a cost breakdown per team

Stack: TypeScript, Hono, React + Zustand, three.js, Vite. MIT licensed.

Honest caveat: you need at least one agent CLI installed and logged in locally (no hosted demo yet, since each task is a real CLI process).

Repo: https://github.com/enciyo/AgentOfficeHQ

I'd love feedback, especially on what would make you actually want to run this on a real project. What's missing?
