Wearable app development, built for the wrist

We design and build apps for Apple Watch, Wear OS, fitness trackers, smart rings and AR glasses engineered around real battery, connectivity and screen-size constraints, not a shrunk-down phone app.

A wearable app is not a smaller phone app

Every constraint changes when the screen moves from your pocket to your wrist. Here's what that means for how we build.

Aspect
Phone app
Wearable app
Screen
5–6 inch touch display, deep menus
1–2 inch glanceable face, one idea per screen
Interaction
Multi-step taps and swipes
One glance, one tap, or a voice command
Power
Charged nightly, always-on radios
Multi-day battery budget, radios sleep by default
Connectivity
Constant Wi-Fi / LTE
Bursty Bluetooth, must work offline

What we build

FAQ

Questions we get from wearable companies.

Apple Watch (watchOS), Wear OS, Samsung Tizen, fitness trackers with SDKs, and custom BLE-connected hardware, alongside the companion mobile app.

We profile power usage during development, batch sensor reads, use low-power BLE connection intervals, and test on physical devices before every release.

Yes, where the hardware supports it. We build offline-first apps that queue data locally and sync automatically once connectivity returns.

Sensitive data is encrypted in transit and at rest, and we architect around HIPAA and GDPR principles for apps handling personal health information.

Fixed price suits a clearly scoped MVP, a dedicated team suits ongoing product development, and time & material suits requirements that are still evolving.
