Managed Services: Mobile App Rescue

See how InApps rescued Two Raw Sisters' undocumented app after a failed vendor handoff, fixing critical bugs and managing it ever since.

Project overview

Food & Wellness App Takeover

The client is a New Zealand-based food and wellness brand with 6,000+ active subscribers. Their previous vendor left zero documentation, unresolved critical bugs, and a live user base already experiencing failures, with no clear path to recovery

InApps audited the entire codebase, executed a clean vendor handover, resolved every critical issue, and has continued operating and growing the product as an ongoing managed-service partner for over a year.

Project goals

  • Audit an undocumented, inherited codebase end-to-end
  • Resolve all critical bugs affecting live users
  • Conduct a structured handover from the outgoing vendor
  • Build real-time data visibility for product and marketing decisions
  • Extend the product with a new web application
What they needed

Client requirements

Across each key area, these requirements shaped every recovery and growth decision we made.

Codebase Recovery

They needed someone to make sense of a system nobody on their side fully understood.

  • AI-assisted audit of the inherited codebase, cross-checked by senior engineers, to map structure and dependencies faster than a manual read-through alone
  • Structured handover process with the outgoing vendor to capture tribal knowledge before it disappeared
  • Documentation rebuilt from scratch, drafted with AI assistance and verified line by line against the live system
  • Risk assessment of every critical component, with AI-flagged hotspots prioritized for senior review

Stability & Bug Resolution

Live users were already affected, there was no room for a slow fix.

  • Triaged and resolved all critical production bugs, prioritized by severity and user impact
  • Zero additional downtime during the fix process, with engineers validating every patch before deployment
  • Regression testing before each release to prevent new issues from slipping through
  • Stable foundation locked in before any new feature work began

Data & Analytics

The team had no real-time visibility into how users actually behaved.

  • AI-assisted data standardization across the existing user base to clean inconsistencies at scale
  • Real-time analytics dashboard for product and marketing teams, with insight summaries for non-technical stakeholders
  • Clean data pipelines built to support future campaigns and segmentation
  • Reporting structured so business decisions could be made without engineering involvement

Ongoing Product Growth

The client needed a partner who would stay, not disappear after the fix.

  • Continued feature development tied to live events, with AI tools used to accelerate scoping and estimation
  • Advised on and led the development of a web version of the application to support expanding content and user needs
  • Long-term operational ownership, not a one-time engagement
  • Predictable delivery velocity quarter over quarter, tracked and adjusted using AI-assisted sprint analytics
The problem

Business challenges

The core obstacles inherited from a failed vendor relationship.

01

Zero Documentation

The previous vendor left without handover notes, leaving the app's engineering history a black box.

02

Live Critical Bugs

Real users were already experiencing failures in production, with no clear fix path in place.

03

No Data Visibility

The team had no real-time view into user behavior, making marketing and product decisions reactive instead of data-driven.

04

Single-Channel Limitation

The product existed only as a mobile app, with no web presence to capture additional growth.
