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

Our process
How a project moves forward
Each project moves through a practical delivery path covering device discovery, small-screen UX, sensor development, real-device testing, launch, and ongoing support.
01
Discovery & Device Audit
We map target wearables, sensors and the companion app to define what's actually possible.
02
Small-screen UX Design
Glanceable UI, interactions and haptics for a 1–2 second experience.
03
Sensor & BLE Development
Native builds with real-time sensor pipelines and low-power Bluetooth.
04
Battery & Field Testing
Real-device testing for battery drain, durability, and GPS accuracy.
05
Store Launch
Submission for the App Store, Google Play and Galaxy Store. Watch-specific guidelines included.
06
Monitoring & Support
Crash monitoring, OS updates, compatibility and ongoing performance tuning.

Frequently asked questions
Questions we get from wearable companies
5 questions answered
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.
