The hardware is finished; the app is the missing piece. We build native iOS and Android companion apps for connected devices, debug them against real hardware, and hand you the protocol documentation along with the code. The app is released under your own developer account.
Pairing, reading device data and sending settings back — the pattern behind our companion apps for screening and health devices.
Devices that report over the network instead of a cable: TCP, HTTP and MQTT reporting, and apps that talk to the device on the same network.
Wired links where wireless is not allowed or not reliable enough — including low-level device code in C on the Android side.
Phone-based 3D capture: our scanning apps drive the depth camera directly in Swift, from capture to a measurable 3D model.
We work against the real device instead: capture the traffic, reconstruct the protocol, confirm every command on hardware, and write it down as documentation your team keeps after handover.
Devices in the field do not all run the same firmware. We test against the versions you actually ship and record where the behaviour differs.
Reconnection, background modes and the differences between Android vendors are designed in from the start and verified on real devices, not patched after launch.
An adapter layer between the device and the app keeps model-specific behaviour in one place, so a new model does not mean a rewrite.
A US foot-care and orthotics company
Two native Swift apps that capture the foot in 3D and turn the scan into a custom orthotics order. Released on the US App Store, with the first app maintained and updated since 2022.

Full write-up (Chinese)Under your own developer account, on the App Store and Google Play. We work in your accounts with the access you grant; nothing is published under our name.
Yes. Most of our projects are delivered remotely: a written scope first, a clickable prototype before development, milestone demos, and a full handover of source code and documentation.
We are in Beijing (UTC+8). Mornings overlap with Europe; for the Americas we work asynchronously with scheduled calls.
Yes. We publish under your developer account and handle review, rejections and ongoing compliance. See App Store & Google Play publishing.
What the product does, which platforms or devices are involved, and your timing. We reply within three working days, in English, with questions or a short written proposal.
