Mobile apps for Bluetooth hardware and offline field work.

We cut ANRs by more than 90% in Trackforce's guard app and built RE-AK's four-sensor research app from an empty repository. We also put senior engineers inside existing teams, usually within two weeks of agreement.

What we work on

We take on three kinds of mobile problem

Connected devices that lose data, field apps that lose signal, and production apps that crash or freeze.

Connected devices and neurotechnology

RE-AK's app records four sources at once with the screen off, for sessions of up to four hours. CLEIO's recovers missed data from the device.

Field systems

Guards lose signal in basements and parkades, sometimes for months. We can design apps that save work on the device first and sync when the network comes back.

Production maintenance

Much of our production work has been on apps other teams built. We trace crashes and freezes to the cause and fix them path by path, which cut ANRs by more than 90% at Trackforce.

Client work in these areas

Trackforce Mobile engineering · Security operations

ANRs down more than 90% in a guard app

A stability push on the app guards use every shift: fewer freezes, and an offline download that stays within its memory limits.

CLEIO Embedded Android engineering · Health technology

Multi-day clinical EEG recordings that survive crashes and dropouts

Inside CLEIO's Android team: a simulated amplifier that let device work start 6 months before hardware arrived, and a crash-safe study lifecycle. No study has been lost to an app crash since it shipped.

RE-AK Technologies Connected neurotechnology

Four-sensor research app, in field use within a month

Built from an empty repository: EEG and wristband data over BLE, USB camera video and GPS, recorded together with the screen off. RE-AK's engineer took it over and kept building on most of the code.

Engagement models

Two ways to bring us in

Dedicated engineering team

We own the app from architecture to release. RE-AK's went from an empty repository to the field within a month, then to their engineer.

Best if you need one team to own a new build or an inherited app.

Discuss dedicated delivery

Embedded engineering

Senior iOS or Android engineers join your repository and sprints at 20 or 40 hours a week. You keep the roadmap.

Best if you have more roadmap than senior engineers.
