Hi Product Hunt! I'm the maker of PALMAGINE. I have a note on my phone called "apps I'll build someday". Last month I actually counted it: 100 ideas. Built so far: zero. That bothered me more than I expected. Most of those ideas were small - a timer for one specific workout, a quiz for my kid, a tracker for one weird habit. None of them needed a big project. They just needed me to be at a computer at the same moment I had the idea, and that almost never happened. When I started asking around, almost everyone had a list like that. Designers, students, parents, people who code for a living. The ideas show up on the train, in the queue at the bakery, in bed at 1am. The desk shows up much later, and by then the idea is gone. PALMAGINE is my attempt to close that gap. WHAT IT ACTUALLY DOES FOR YOU You're on the train and think "I want a bill splitter that rounds to the nearest 100 yen." You type exactly that. A minute later it's running on your phone. You tap around, say "make the buttons bigger and add a history", and it changes. By the time you get off, you have something you'll actually use. Say it, and watch it run. You describe what you want in plain words. An AI agent writes and edits the code for you. It works with Claude, GPT and Gemini - you bring your own API key and pay the provider directly. It runs right where you made it. Web apps (HTML/CSS/JS), React and Vue 3 run on your phone in seconds. No cable, no second device. Flutter and Expo projects can be built in the cloud with GitHub Actions in your own account - that one takes a few minutes. The code is actually yours. Everything lives in your own GitHub repository. There's a code editor in the app if you want to touch it by hand, and you can open the same repo on a laptop later. Nothing is locked inside the app. The app is free. No subscription, no in-app purchases. There are ads on the settings screen and when you start a cloud build - never in the chat or while you're using what you built. WHY I THINK THIS MATTERS There's a quiet assumption in software: phones are for using things, computers are for making them. For large projects, I think that's still true. You want a big screen, a terminal, and a few hours of focus. But for small, personal tools, the bottleneck was never the computer. It was the gap between the moment you have the idea and the moment you're able to act on it. I spent years thinking my problem was "I don't have time to code." It turned out my problem was "I'm never at my desk when I want to." Two questions for you: 1. What's a small app you've wanted for years but never sat down to build? Reply with it - I'll build the most-requested ones on my phone and post the results right here in the comments. 2. Do you think real software can start on a phone, or is the desk still where the actual work happens and I'm romanticizing my commute? Thanks for reading. I'll be here all day.
