I’ve spent the last 10 months building Zelus, a walking app that turns your real-world distance into progress through virtual challenges. It’s now live on iOS and Android, and I’ve reached the point where I know it too well to test it objectively. I’m looking for people willing to try it and tell me what’s confusing, awkward or broken — including any crashes or, hopefully not, database wipes. Blunt feedback is welcome. Ratings are also appreciated if you genuinely like it. Video: https:...

Guys it was a long journey for me from beginning but it was worth it , i have built cvinsight.me 10 months ago and it kept spreading through whatsapp and word of mouth and now we are a family of 2700 users , among which 80+ are paid ones

dev background, so building the thing was the comfortable part. now I'm at the part everyone says is hard and yeah, they were right. quick context: it's an AI version of yourself people can talk to. you feed it your own stuff and it answers in your voice, so if your thing is your knowledge you're not stuck answering everyone one by one. aimed at coaches and solo experts first. product's ready. the problem is 100% distribution and it's humbling. I've been: trying to DM coaches directly (s...

The basic principle is very simple: when you encounter new words, save , review, and memorize. this worked for me, do you think it will work for you?

I had a very specific backlog problem: I’d save a food Reel because it looked good, then never find the ingredients or steps again when it was time to cook. So I built Reelish, an Android app that lets you share or paste an Instagram Reel, TikTok, or YouTube Short and turns the usable details into a recipe card. From there, you pick only the recipes you want to make and it combines their ingredients into one grocery list. One thing I intentionally did not want: an app that acts certain when ...

The last 24 hours have been something I’ll probably never forget. My first sale came completely out of nowhere. I got a notification, checked my dashboard, and realized someone had actually paid for my app. I couldn’t believe it. Then I shared the news on Reddit. A few hours later, someone commented, “Well, I just made you another one.” I honestly thought they were joking. Then I checked my dashboard again. They actually bought it. Not long after that, another Redditor became customer #3....

Got tired of every "free" AI tool hiding behind login walls and 3-uses-a-day limits, so I built my own set and made them actually free — no accounts, no paywalls. They run on open-source models (Nemotron, Gemma) via OpenRouter, with a Next.js frontend on a small VPS. The set: text summarizer (20k chars), AI-text humanizer, paraphraser, grammar fixer, hook generator, SEO meta generator, Instagram caption writer, YouTube summarizer, and a "which AI should I use?" quiz. Hub:...

I am my target user, but organic TikTok and Instagram videos aren’t doing the trick. How should I get my first 100 users? Just friends and family?

Hey everyone! I’ve decided to build my project completely in public, so here is the very first screenshot of my analytics dashboard after 7 days of being live. To give you some context on these numbers: I recently launched a small micro-SaaS with two subscription tiers ($12/mo and $29/mo). It’s a tool designed to help freelancers streamline their client onboarding and brief creation, which is a problem I personally faced a lot. The Week 1 numbers: Uniques: 47 Sign-ups: 4 Paying us...

The original idea for my side project was an AI creator for Notion widgets. You describe what you want, choose a style, and it generates and hosts the widget so you can embed it in Notion. That was the product from the beginning. I added a catalog of ready-made widgets later because the site felt a little empty without them. I thought the free catalog would make the platform more useful and eventually lead people toward the AI creator. The free part ended up becoming the main source of tra...

Every single time I ask Claude or ChatGPT to build a UI, it spits out the exact same generic SaaS layout. Same rounded corners, same glassmorphism, same boring structure. So I built VibeCurb . It’s completely free and open-source. There's no app to install or wrapper to pay for, it’s just a collection of extremely strict skill.md files that you drop directly into your AI workspace. What it actually does: Kills the generic glassmorphism and rounded-corner spam Enforces viewport-s...

I'm a staff product designer by trade and was working in big tech. I hated that most of my week became alignment and reporting, like standups, end-of-week updates, devs asking what changed in my file. I spoke with a bunch of other designers, and this was the biggest complaint they had also. So I built Design Recap, a Figma plugin that reads your file and writes up what you've recently worked on, plus a changelog. It covers the end-of-week update, when you're drawing a blank at standup, and t...

Problem: macOS has desktop widgets, but Apple's Photos widget only shows "Featured Photos" it picks for you. You can't say "show this photo of my dog." Apps that fix this are paid. Solution: PhotoWidget — real macOS native widgets (WidgetKit). Not an overlay app pretending to be a widget: macOS renders these itself, so nothing runs in the background. Open the app only when you want to add or organize photos. How to use: Drag photos into the app (crop box appears ...

Hi everyone, I am a software developer by profession, and over the past few months I've been working on a side project called PodTyper. You can access it at https://www.podtyper.com Instead of downloading audio files or uploading episodes manually, you just paste a podcast URL (Spotify, YouTube or Apple Podcasts) and it generates a transcript along with AI-powered summaries. I originally built it because I found myself constantly wanting to search through podcast episodes instead of list...

Launched LeaseSnipe this week. You upload a lease PDF and get a plain-English report in about 60 seconds: risky or unusual clauses flagged, real move-in costs broken down, and each flag checked against the landlord-tenant law of your state (all 50 + DC). The idea came from watching someone I know sign a lease with a security deposit at 2x the legal cap in her state. She found out afterward. The asymmetry bugged me. The landlord has a lawyer, the tenant has a PDF and 24 hours. Stack: TypeScri...

I kept seeing claims about how crazy the card market is right now and realized nobody could actually answer “is the market up or down?” So I built an index the same way the S&P 500 works, price-weighted, divisor adjustments, membership updates daily, using TCGplayer market prices, with history back to Feb 2024. I’m hosting it for free as a passion project at https://poke500.com/ if anyone wants to take a look. The newsletter automatically sends out a weekly update as well every Friday if t...

Hi everyone! I recently launched Folivy, an iOS app I built to make plant identification feel like an ongoing discovery experience rather than a one-time scan. You can take a photo to identify a plant, save it to your personal herbarium, view your discoveries on a map, and explore nearby observations shared by other users. My goal is to help people gradually build their own plant collection and personal nature journal. I’d really appreciate honest feedback on the idea, user experience, and w...

After working as a 3D artist in the film and advertising industry for the last 17 years, I decided to give gamedev a go. I joined a random facebook group and I met an amazing programmer and together we started working after hours to produce videogames. It's been months and months of hard work after our actual jobs that are also hard work 😂 This is our 3rd attempt at it. It is a game called Skinator. It's a game where you can steal your enemy's body parts and install them into your own body. We...

I’ve been working on Prolo Ring, a wearable input device designed to control different types of devices without carrying a separate controller for each one. In this demo, I’m using the same ring across: Laptop Phone Tablet AI glasses VR headset A Tap + Hold switches control from one device to the next. Once connected, the ring can handle things like pointing and clicking, scrolling, media controls, page turning, teleprompter navigation, and VR interface control. The bigger ...

Hey everyone, I spend way too much time hunting for new tools, APIs, or data sources for my own projects. Here are 4 of the most interesting open-source repos that surfaced over the last few days that are actually great for solo builders: hasaneyldrm/exercises-dataset (HTML | ⭐ 13.7K): A massive dataset of 1,324 fitness exercises, including animation GIFs, muscle-group data, and instructions. If anyone here is sketching out a health, habit, or longevity tracking app, this is an absolute ...
