What this studio won't trade

COLLECT NOTHING AT ALL

Straight answers about your data

Haplo AI, ShipHappens, Markdown2PDF and Annot8 collect nothing. Your chats, trips, workouts and documents stay on your device. Bilbo sends anonymous usage stats, Barrier is paid for by ads, and Haplo AI Investing asks our server for its analysis. The privacy policy lists every app.

100%  Swift
0%     Electron
native  SwiftUI

Native, not wrapped

Every app is written in Swift for the platform it runs on, including the Watch app, the widgets and the Live Activities. Lean, fast, and easy on the battery.

The story so far

Five years, nine apps, one developer. The log, abridged.

2021
The studio boots up. Haplo, LLC is founded and ships Haplo AI Investing, AI stock analysis before it was cool. Nights and weekends.
2023
Focus and tooling. Barrier takes on doom scrolling with Apple's Screen Time API, and Annot8 turns ML image annotation into a hotkey game. The on-device habit sets in.
2025
Five apps in one year. Haplo AI brings language models fully on-device, EasyLogo and Markdown2PDF ship for creators, Cinder hits the gym, and ShipHappens automates the release chore that made all of it possible.
2026
Off the beaten path. Bilbo takes the on-device playbook travelling, planning whole day-by-day trips on your iPhone, with no account, and the trips stay on the phone.
