Open toolThese aren't App Store apps — they're installable web apps. There's nothing to download, no account to create, and no updates to chase. You open a tool in your browser, install it in a couple of taps, and it lives on your home screen or in your applications menu just like a regular app. It opens in its own window, works offline in the cockpit or the hangar, and keeps your data on your device. Nothing gets uploaded, nothing follows you around.
The tool will open in its own window and show up in your Start Menu, Dock, or Applications folder. You can launch it like any other app, even when you're offline.
The tool will appear on your home screen with its own icon. Tap it to open full-screen, without the browser bar — just like an App Store app.
On most Android phones you'll also see a prompt at the bottom of the screen the first time you visit — you can install straight from there.
I'm a powered parachute and airplane pilot, mechanic and software engineer. I build these tools to help people progress in their aviation journey — whether you're a student pilot, a seasoned aviator, or somewhere in between.
Every tool here is free, fast, and focused on one job. No accounts, no ads, no feature bloat. They work on your phone in the cockpit and on your desktop at the flight school.
I also build custom aviation software — if you're a flight school, instructor, examiner, or aviation business that needs a tool built right, that's what I do professionally through Parachute River.
I build what aviators actually need. Join the Discord to share ideas, give feedback, or just talk aviation with other builders and pilots.
