Process

Our Approach to App & API Maintenance

A structured process that delivers real products — not just code.

01

Codebase Review & Audit

We review your existing source code, identify technical debt, security vulnerabilities, performance bottlenecks, and document what needs immediate attention.

02

Technical Assessment Report

You receive a written technical assessment listing every issue found, its severity, and a recommended fix prioritized by business impact.

03

Critical Bug Fixes

We fix the most critical bugs first — crashes, data loss issues, payment failures, and store compliance problems that could get your app removed.

Performance Optimization

API response time improvements, database query optimization, image compression, memory leak fixes, and app startup time reduction.

Why Us

Why BitsAccurate for App & API Maintenance

01

We work with other developers code

Most studios refuse messy legacy codebases. We review, document, and take ownership of existing projects — even poorly written ones.

02

Honest assessment upfront

Send us your codebase. We review it, give you an honest technical assessment, and tell you exactly what is broken and what it costs to fix.

03

No lock-in

We improve your existing app without rewriting it from scratch (unless necessary). You keep your codebase, your history, and your app store reviews.
