Train, and log it from your wrist.
Cinder logs a set in seconds, syncs with HealthKit, and puts a Live Activity on your Lock Screen — with an AI that knows your actual history.
iOS Apps That Help You
One developer, nine apps on the App Store. Native Swift for iPhone, Mac and Apple Watch — and most of it runs entirely on your device, with no account and nothing phoning home.

Why these exist
Built the way software used to be
Four things most apps ask you to accept, and what this studio does instead.
Problem
Your data leaves your phone the moment you open the app.
uploading…
↓
Haplo
The processing happens on your device. There is nothing to upload, so nothing is.
Problem
Everything is a subscription now, forever, with no way to just buy the thing.
Buy once
OPTION ON EVERY PAID APP
↓
Haplo
Every paid app has a one-time lifetime option next to the subscription, and Barrier is free with no in-app purchases at all.
Problem
Cross-platform wrappers that feel heavy, slow and vaguely foreign on Apple hardware.
100% Swift
0% Electron
native SwiftUI

Haplo
Every app is Swift, built for the platform it runs on — including the Watch and the widgets.
Problem
You file a bug and it disappears into a queue behind a thousand others.

What you can actually do
Run a language model with the wifi off.
Haplo AI runs Llama, DeepSeek and Phi entirely on your device at 32K context. It works on a plane, and it works without a subscription.
Plan a whole trip before you land.
Tell Bilbo where you are going and it builds the days out — sights, food, and the route between them, with opening hours and tickets attached.
Ship an update in half an hour.
ShipHappens does screenshots, localization and App Store Connect uploads in one Mac app. It is the tool this studio built to ship the other eight.
