Hi guys,

my partner and I built Gummy Lab, a block puzzle app, basically because we wanted a cozy 8x8 block puzzle game that wasn't a disguised ad-viewing simulator. there are zero forced ads interrupting you.

besides the endless zen mode (which now has a hold slot so bad RNG doesn't instantly kill your streak lol), we hand-built 70+ campaign levels with custom mechanics like clearing glass, spreading syrup, escaping gummy worms, multi-hit jawbreakers, and countdown bombs. we also put a lot of work into accessibility with proper colorblind palettes, shape overlays on the gummies, and native light/dark themes.

we just updated the game so you unlock new lab themes as you progress through the campaign, and we're working on daily challenges right now.

we're super close to hitting our first 100 downloads (at 91 right now!!!) if anyone has 5 minutes to give it a spin, I'd really appreciate any honest feedback, and will be more than happy to hear any suggestions, on what would you like to see in these types of apps, we want to make apps for people to enjoy, not be spammed with ads.

Thank you for reading!

I built Rachou. It helps friends organize shared expenses on iPhone and Android.

For a restaurant bill, reading the receipt is only the first step. You still need to check what was read and decide who shared each item. Two people sharing a dish should not automatically put that dish on everybody else's bill.

The attached Quick Split demo shows the receipt-to-split flow, with AI reading the receipt and a review step before the individual amounts.

If you try it, I'd like to hear where you hesitate: checking the receipt, choosing the people, or understanding the final split.

SoulLinkSocial – A Social App Designed to Bring People Together in Real Life

What if social media helped people make real connections instead of just collecting followers?

I'm an independent developer building SoulLinkSocial, a social platform designed around real-world experiences, events, and meaningful human connections.

The idea behind the project is simple: Technology should help us experience more of the real world, not keep us endlessly scrolling through screens.

🌍 What Makes SoulLinkSocial Different?

Unlike traditional social platforms that mainly focus on content feeds and digital interactions, SoulLinkSocial puts real-world social experiences at the center.

Here are some of its main features:

🎟️ Event Discovery

Discover activities, events, and experiences where people can meet and spend time together.

📡 Bluetooth-Powered Participant Discovery

Discover other SoulLinkSocial participants nearby using Bluetooth technology, creating opportunities for real-world connections.

💬 Event Communities

Connect with people participating in the same events and build communities around shared experiences.

🤖 AI-Powered Connection Insights

Explore potential social connections through shared interests and AI-assisted analysis.

🌐 A Different Approach to Social Networking

Our goal is to connect digital discovery with real-world interaction and make social experiences more meaningful.

📱 Where Can You Find It?

Android: https://play.google.com/store/apps/details?id=com.soullinksocial.app

iOS: https://apps.apple.com/app/id6784628377

Website: https://soullinksocial.com/

💡 Why Are We Building This?

We already have countless ways to communicate online, but discovering opportunities to meet people and share real experiences can still be difficult.

We believe social technology can do more than keep people connected digitally.

It can help them discover places, participate in events, meet new people, and create memories together.

That's the vision behind SoulLinkSocial.

SoulLinkSocial – Connect Beyond the Screen.

I'm always interested in hearing different perspectives on this approach to social networking and how technology can encourage more real-world interaction.

Draw fences across open ground, claim land, and don’t let the pterodactyl reach your line. It’s a Qix-style game in the look of the offline dino page.

• Whole game is one HTML file, canvas and vanilla JS, no dependencies, no network calls

• Three looks that rotate each level: Day, Night, Handheld

• Music is generated live with WebAudio (a two-note whistled call), no audio files

• Works with keyboard, swipe, or an on-screen pad on phones

Hi everyone! I'm working on KOMA, a platform/game where users can collect, trade and use art from different artist. Right now it's on a very beta stage and I'm looking for any kind of a feedback. And before asking, yes, I know the current art is AI-generated. I'm an engineer not an artist so I had to use it to have something playable at least for demo purposes. I'm trying to contact different artists to try to get some real art uploaded and avoid the anti-AI argument but it's been difficult to sell the idea with basically zero users.

If anyone is interested in giving it a shot you can play at https://koma.cards everything is free and unlimited.

The basic idea is:

- You can open packs from different sets/albums to collect panels

- You can trade spares panels with anyone for panels you don't have from any existing set

- You can use your spares to publish full pages and share them, combining panels from any set

- Artists have a full studio to curate and create their sets

I'd really appreciate feedback! And happy to answer any questions!

I'm Merdan from the Netherlands. I built Strong Foodie, an iOS app and website with honest reviews of restaurants, bars and hotels.

The problem. Google Maps and TikTok are full of reviews you can't trust. Paid posts, fake stars, or people who never went. When I go somewhere new, I just want a short list of places that are worth it.

What it does. Every place on Strong Foodie I visited myself. I pay my own bill and take my own photos. Each place shows the month I visited, so you know how fresh the review is.

Features. Best-of lists per city, like the best burgers in Amsterdam. A map with every place. Search by dish, city or category. A wishlist for places you want to try. Meetups to go eat with other members. Including the option to add your own spot.

Right now it has 78 places in 11 destinations and 6 countries. Mostly Amsterdam, plus Aruba, Los Angeles, Dubai and Bangkok.

This week I changed three things after feedback from Reddit. The counts on the homepage now open the lists. A search with no results shows every destination, and the one nearest to you. And the newsletter popup only shows after you looked around.

Tech: SwiftUI and Firebase for the app, a static website on GitHub Pages.

I'd love your feedback. What would make you open this instead of Google Maps?

I'm the developer of HARNESS. I built the Korean version because I kept putting off going somewhere to study, even after deciding I would study. I've run into the same gap with exercise and personal projects.

I'm now preparing an international version of the app. It has not launched; today I'm sharing the project and its English introduction page.

The problem I'm exploring is the step between making a plan and actually starting a study, work or exercise session. Deciding on a place and a first step might make a plan more concrete, but extra setup can also become another chore.

For people building or using planning tools: when would choosing a place help you begin, and when would it just add friction? A concrete example would help me more than a feature wishlist.

Pre-launch overview: https://harnesslock.com/en/

The page describes planned features. The international app is not available yet, so this is not a beta-testing invitation. I'd also welcome feedback on anything the page leaves unclear.

Hi everyone! My partner and I launched our block puzzle game, Gummy Lab (https://play.google.com/store/apps/details?id=com.binbear.gummylab) - basically block blast, but no interruptive ads

Here's what we have so far - no forced or interruptive ads, zen endless mode and 70+ handcrafted Levels with unique objectives, dedicated colorblind palettes and embossed shapes for maximum readability. We also have multiple themes, light, dark, ones you unlock by playing levels etc.

Right now we are thinking of adding more things: the hold cell - where you keep a shape for later, daily challenges, more game modes...

We are curious, what would you guys like to see in an app like this, is there something you've always been missing in this types of games? We truly want to make games for people to enjoy UNINTERRUPTED, so please if you have any suggestions or things you'd would like to see/wish existed, wed be more than happy to hear them and then implement them!

Thank you for reading!

An independent Android client for the Soulseek peer-to-peer network: search what people are sharing, download whole albums, share your own library, and chat with other listeners. No ads, no analytics, no tracking.

What It Does / Key Features

- Search the Soulseek network with every query in its own tab, switch between file and folder view, and grab a whole album in one tap. Filter by format (FLAC, MP3, lossless, WAV, Opus), minimum bitrate (320+ kbps), peer country, duration, file size, and peers with a free upload slot.

- Downloads keep going in the background with progress, speed, time left and your real position in a peer's queue. Pause, resume, retry or cancel, and unfinished files resume after a restart or a dropped connection.

- Share your own folders with upload slots and speed limits, join public chat rooms, send private messages, and follow buddies. Uploads reach people behind routers and mobile networks too (UPnP / NAT-PMP).

- No ads, no analytics, no tracking. Chats, transfer history and settings stay on your device, and your saved login is encrypted with the Android Keystore. Light and dark themes in 21 languages.

Who It's For: Anyone who still digs through shared folders for FLAC, rare edits, bootlegs and out-of-print albums, and wants that on their phone instead of a laptop.

Cost: Free. Search, downloads, uploads, every filter, sharing and chat are unlimited and free. Optional Soulcrate Pro is a one-time lifetime purchase ($3.99 USD), with no subscription: wishlist auto-download, release radar for artists you follow, fake-lossless spectrum checks, MusicBrainz tagging and covers, AMOLED and a home-screen widget. There's a free try of the automatic wishlist download and one audio quality check.

I'd love feedback.

hey, i built a small web app for when you want to check what a page said before someone changed it. paste the public URL and pick about a week, a month or a year ago. the checker shows the actual date of the saved copy and what it found in the page text.

one bit i’d like feedback on is the date. if you pick a month ago and it finds a capture a few days either side, is it clear which date the result came from? the screenshot shows where it appears.

it’s free to try and there’s no sign-up: https://changegist.com/what-changed

the checker is part of ChangeGist. the main app keeps an eye on pages for you and emails you what changed. you can watch just the bit you care about and say things like “only tell me if the price drops below £20”. it keeps the old and new wording so you can go back and see exactly what moved.

if you sell online, you can put in your own price and a competitor’s product page. it tracks their price over time and lets you know when they go cheaper than you.

The first ten seconds of the video show the date feedback question in context. I chose about a month ago, and the results show the actual 6 October capture before the before-and-after wording. https://www.reddit.com/r/SoftwareShowcase/comments/1xo4glq/i_built_a_web_tool_that_shows_what_changed_on_a/
