In the maker’s words, at launch

i built a heart rate zone training app for runners. ios + apple watch. custom zones, real-time haptics, post-run graphs. all the “smart” stuff you’d expect. but i never talked to a single runner before building it. not even myself lol. started as a thesis → kept building → added features → added a paywall…

  Steps: Workout & PedometerMar 2026 · getsteps.app · ▲98

  Hey HN, I'm a solo developer and I built Steps: Workout & Pedometer, an iOS pedometer and workout tracker. Last week, two German iOS publications wrote about the app. I didn't pitch them. I didn't send a press release. I didn't even know it was happening. I woke up to a spike in downloads, checked the analytics, and traced it back to their articles. That coverage pushed the app past $1,000 in sales. I still have no idea how they found the app. I'm wondering if anyone here has experience getting featured in publications, whether organically or through outreach. What worked for you? Any tips…

  touch grass2025 · touchgrass.now · ▲525

  I wanted old school social media back. Actual connections with friends. Not pity likes and performances and highlight reels. All my friends have stopped posting. Everyone's a lurker now. I'm a lurker. The only time I see what anyone's doing is when it's a humblebrag. I have no idea what's actually going on in my friends' lives besides the ones I see every week or so. So I built touch grass. You post once a week: 3 easy questions, max 3 photos. Sunday 6pm mountain time (yeah its my time zone) everyone's posts unlock at the same time. You catch up on what your people have been doing, then…

  Ran my first marathon. Didn’t want to keep paying so much for Runna. So I built a running coach app, and then kept improving it more and more, i think it’s pretty good now. Give it a try and share your thoughts.

  1 min workouts for people who sit all day2025 · shortreps.com · ▲153

  I am a software developer and in the last few months after recently becoming a father I was barely finding time for a proper workout. Recently I was reading about new research on Snack Exercises and how beneficial mini workouts of less than 2mins every so often, during the day are to our body. So, I decided to build an iOS App for me and others to help with this. The app generates a list of exercises that I need to tick to complete daily or loose my streak. The algorithm takes into account muscle groups and balancing the exercises to hit most main muscles. I also stayed going through all…

  Vibe coded iOS workout app with Apple Watch supportFeb 2026 · apps.apple.com · ▲8

  I spent a month to put together a workout app without writing a single line of code by hand. It's on par with many apps like Fitbod or Fitness AI. Got approved on iOS App Store. Let me know if you want free access, only thing I ask is to give me genuine feedback and one feature you would like to see. I will be asking Codex/Claude to rank the top features and implement it.

  Cardio2025 · mycardio.co · ▲134

  I kept forgetting names and contacts… so I built Cardio. So I built Cardio: a digital card/profile you can share with just a QR code or link. It saves directly into your contact, so no more “Who was this again?” moments. - Built with Next.js, Adobe, and Stripe - Uses AI tools (Cursor, ChatGPT) to accelerate development - No app install needed: just tap, scan, or share I’m a solo builder from a non-dev background, and this is my first product. I launched it 10 days ago and made my first sales. Would love any feedback! performance, UI clarity, growth ideas or anything. Thanks HN!

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
