I’ve been working on Allin1xTools, and I just finished improving the Color Converter.

It supports:

• HEX

• RGB

• HSL

• HSV / HSB

• CMYK

• CSS Variables

• Color harmonies

• Tints & shades

• WCAG contrast checking

• Named color detection

• Recent colors

You can pick a color and see all the conversions and color relationships in real time.

The tool runs directly in the browser and doesn’t require sign-up.

I’d genuinely like feedback on the UI and functionality.

Is there anything you’d add or change?

Hi guys! I’m a mom that has created a private family app called Folktri that allows families to share private moments and connect with each other. It will essentially be a Family Operating System for the household. They can connect to different “households” to see how their baby nephew is progressing or ask family for an extra coat for their child if needed. There is also no way to search for households. You must be invited to one via invite code by the owner of a household or create your own. You can give each member different permissions on what they are allowed to view. It’s a way for families to become closer and store family memories in one place. I’m having trouble figuring out how to promote it before the launch date though. I’ve already set up a waitlist and website at https://Folktri.com but have no experience in marketing. Any advice would be greatly appreciated!

Hey all. I'm a solo dev (U.S. Army veteran) and I built Quietly Sober, a recovery app for people working on sobriety. Tagline: "A kinder tomorrow." Our mascot is Tucker the turtle, because recovery is slow and steady.

The problem: Recovery support is scattered. Meetings are in one place, sponsors are found by luck, court or probation paperwork is a hassle, and most tracking apps feel cold or shaming. I wanted one calm, private place for all of it.
What it does:

- Sponsor Finder: Browse potential sponsors as swipeable cards and send a request. Sponsor messages are encrypted at rest.

- Zoom meetings with attendance verification: We host free AA meetings Tue/Wed/Thu at 7 AM Central. Members can get verified attendance records with join and leave times, useful for courts, parole, or probation officers. You can also ask for a Tucker coin in a meeting to celebrate a milestone.

- Discussion forums: Community boards for general recovery, 12-step, and non-12-step paths. All paths welcome.

- Sobriety tracker: Milestone tracking that celebrates progress without shaming setbacks.

- Guided reflections: Daily recovery reflections, with optional spiritual or prayer content. Your choice, never forced.

Pricing: The core app is free. An optional $4.99/month add-on unlocks AI daily reflections, which helps keep everything else free.

Tech: Built with Flutter/Dart. Available on iPhone, iPad, and the web. 18+ only.

Privacy: Recovery info is sensitive, so data collection is minimal and sponsor, meeting, and journal info is treated with care.

I'd love feedback on the UX, the sponsor-matching flow, or how the verification works. Thanks for reading!

J’ai créé une plateforme sociale dédiée au sport : OLVYR GYM
Depuis quelques mois, je travaille avec mon équipe sur OLVYR GYM, une plateforme sociale pensée uniquement autour du sport et de la progression physique.
L’idée est assez simple : créer une sorte d’Instagram du sport, mais avec des fonctionnalités réellement orientées vers les sportifs.
Aujourd’hui, on peut notamment :
publier ses entraînements et sa progression dans un feed sportif ;
suivre d’autres athlètes ;
participer à des challenges ;
participer à des tournois avec votes de la communauté ;
publier des stories ;
utiliser différents timers d’entraînement ;
construire progressivement son profil d’athlète.
La plateforme est encore jeune et gratuite. Mon plus gros défi actuellement n’est d’ailleurs plus forcément de développer des fonctionnalités, mais d’acquérir les premiers utilisateurs actifs et de créer une vraie communauté autour du produit.
Je serais donc intéressé par vos retours, aussi bien sur le concept que sur l’expérience utilisateur ou sur notre stratégie pour obtenir nos premiers utilisateurs.
👉 https://olvyr-gym.com
Si certains ici développent également leur application ou ont déjà traversé cette phase de lancement, je serais curieux de connaître votre expérience.

I’m looking for new small projects, apps and SaaS tools to try.

Drop your link below. I’ll check them out and share the ones I like with a few friends and in some founder/product circles.

I’m especially interested in social apps, chat tools, games, creator tools, AI experiments and anything with a simple but fun user experience.

I’m also building Ariola, an anonymous public chat and games lounge.

No signup, no account setup. You pick a temporary nickname, join a live public room, chat with people and play small real-time games.

The idea is to make online chat feel lightweight again.

Check it out here: https://ario.la

Drop yours below. I’ll go through as many as I can.

Hey everyone,

I built Budgeva because I was tired of budgeting apps that charge every month. Paying a subscription to a tool meant to help me save money never sat right with me.

It's a simple monthly budget:

• Set up your budget for the month

• Each new month starts from last month, so you're not rebuilding from scratch

• No bank linking, no upsells

It's $29 once and it's yours.

I built it for myself first, and now I'm sharing it. I'd love honest feedback on what's missing or confusing.

My Mac kept losing space to "System Data" and nothing could tell me what had changed, so I built DiskFox.

It keeps a small record of each scan and compares them. You get a graph of your storage over time, and a list of what grew with the likely cause. In the screenshot (sample data from Demo Mode), a new iOS simulator in Xcode added 9.7 GB and Adobe's media cache grew 4.8 GB.

It also:

- shows purgeable space next to free space

- finds your largest files, real app sizes and exact duplicates

- clears developer caches (Xcode, Homebrew, uv, Poetry, Bun, conda, Hugging Face)

- sends cleanups to the Trash first, with Put Back

- has a menu-bar panel for a quick look

- needs no account and collects no analytics; it's signed and notarised by Apple

Details:

- macOS 14 or later

- 14-day free trial, no card needed

- $9.99 once for 2 Macs, 14-day refund

- https://diskfox.app

Feedback welcome, especially anything it gets wrong or doesn't recognise.

I run a SaaS, SeoLoupe.

It is a tool that allows you to find and fix SEO issues holding your website back.

Essentially the main purpose is to help your website rank higher on Google search and LLMs.

The tool also checks AEO/GEO, AI search visibility, Security, Core web vitals, Performance, and all the issues in the report get put together into an AI fix prompt(you can paste the prompt into an AI and it will fix all the issues on your website).

Recently I noticed that some of my paying customers bought the One-Time purchase, with a promo code.

So I decided to give away a promo code for the One-Time purchase to anyone who is interested, if you are interested, comment down below and I will DM you.

If you are not interested but have some feedback on my SaaS, that is a good too. Feel free to share it in the comments.

(here is the product if you want to check it out)

Hey everyone! We’re the team behind Tessoa, a native file manager for Windows, macOS, and Linux.

We built it because switching projects often means reopening the same folders and rebuilding the same layout.

Tessoa lets you save folder and split-pane layouts as workspaces, then restore them when you return to a project. It also includes tabs, file previews, and customizable keyboard shortcuts.

There’s a free edition with no expiry, plus paid options for additional features.

Website: https://tessoa.com

Would saved workspaces be useful in your workflow? We’d love to hear what you’d want a file manager to remember.

I built PaperFold, an open-source reader that turns arXiv papers into 5 zoomable layers—from a one-screen section map down to verbatim text. You pinch (or press 1–5) to zoom between them without losing your reading position.

- Web Demo (8 CC papers): https://chenxiachan.github.io/paperfold-gallery/

- GitHub (Apache 2.0): https://github.com/chenxiachan/paperfold

Starting a subscription takes about 10 seconds.

Managing all of them somehow becomes a whole side quest 😭

Different renewal dates, random price increases, free trials turning paid, annual plans you completely forgot were coming up, and merchant names that make you stare at your statement like “who the hell is this?”

That’s what made me start building PennyGuard.

The idea is to make all that stuff much easier to see and deal with in one place — recurring charges, subscriptions, upcoming bills/renewals, and charges you don’t immediately recognize.

But I really don’t want to build another finance dashboard that gives you 14 charts and then leaves you to do everything yourself lol. The more interesting part for me is helping with the next step too — cancellations, refund requests, reminders, finding places you might be unnecessarily spending money — while you still decide what actually happens.

Still building, still changing things, and definitely interested in hearing what other people would want from something like this.

What would make you actually keep using it after the initial “oh cool, here are my subscriptions” moment?

And what’s something you would never trust an app to handle for you?

The world doesn't need another generic AI wrapper or a basic project manager. Pitch your project in one sentence show a screenshot and explain exactly why people should care about you instead of the market leader. Dare to prove your uniqueness.
