Studio 91 develops robust, privacy-first Android utilities and workflow automation tools. We design focused client-side software that streamlines daily operations for independent contractors and mobile professionals.
Studio 91 is an independent development lab focused on solving high-friction operational tasks on mobile devices. We believe mobile utilities should empower users without compromising system security, battery life, or personal data.
We keep the work on the user's phone: screen parsing and decisions run locally, so our apps react fast and never need your account credentials. The small amount of diagnostic data we collect is listed in our Privacy Policy.
No middleman servers touching your active sessions. Complete offline independence whenever feasible.
We publish what leaves the device and why, and delete it on request.
No ads, no ad trackers, no bloat. Small tools that do one job well.
Delivering technical precision across modern mobile architecture and system-level automation.
Building resilient, native Android applications utilizing modern Jetpack libraries, Kotlin Coroutines, and responsive UI components.
Architecting robust on-device automation systems via Android AccessibilityService, custom event dispatching, and gesture synthesis.
Sub-second heuristic text recognition, structural UI hierarchy analysis, and multi-parameter rule engines that run locally on the device.
Encrypted local storage for licence data, signed releases, and minimal data collection by design.
Low-overhead polling algorithms, adaptive wake scheduling, and strict memory budgeting tailored for non-stop mobile execution.
Domain-tailored tools designed specifically to give independent courier drivers clear control over schedule filtering and trip values.
