Mobile Software & Automation Engineering

Software engineered for mobile productivity and precision.

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.

100% On-Device All logic, parsing, and decisions execute locally on your hardware.
Zero Account Harvesting No external cloud proxies, credential storage, or telemetry leakage.
Native Android Engineered in native Kotlin with low battery drain and minimal latency.

Independent software engineering with a privacy-first ethos.

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.

Unlike conventional tools that funnel data through opaque cloud infrastructure, our engineering prioritizes client-side execution. By running heuristic parsing and decision loops directly on the user's phone, we guarantee both microsecond responsiveness and absolute privacy.

Local Autonomy

No middleman servers touching your active sessions. Complete offline independence whenever feasible.

Adaptive Humanization

Intelligent timing variance and randomized interaction distributions that preserve natural OS usage patterns.

Focused Utility

No bloatware, aggressive ad networks, or background trackers. Pure, purpose-driven utilities.

Our Areas of Expertise

Delivering technical precision across modern mobile architecture and system-level automation.

Mobile Development

Building resilient, native Android applications utilizing modern Jetpack libraries, Kotlin Coroutines, and responsive UI components.

Software Automation

Architecting robust on-device automation systems via Android AccessibilityService, custom event dispatching, and gesture synthesis.

Real-Time Screen Parsing

Sub-second heuristic text recognition, structural UI hierarchy analysis, and multi-parameter rule engines executed on bare metal.

Client-Side Security

Hardware-backed cryptographic storage, encrypted local preferences, anti-tamper safeguards, and zero-knowledge data pipelines.

Performance & Battery Efficiency

Low-overhead polling algorithms, adaptive wake scheduling, and strict memory budgeting tailored for non-stop mobile execution.

Logistics & Gig Utilities

Domain-tailored tools designed specifically to give independent courier drivers clear control over schedule filtering and trip values.
