The challenge

Taking over a partially written app is a different job from writing one. The code that exists has to be understood well enough to judge it, kept where it is sound and replaced where it is not, all while the release date stays where the client already put it. In a subscription fitness product the parts that cannot be approximate are the ones users notice least: plan delivery, progress state and the subscription itself.

CodigoDelSur's expertise brought Shred to life, allowing workouts to adapt to available equipment like dumbbells or bodyweight.
Shred, an innovative fitness solution by CodigoDelSur, uses an adaptive AI engine to suggest weights and time rest.

our approach

CodigoDelSur assessed the partial Android codebase, completed it and shipped it to release, working against a Node.js backend shared with the iOS product. The work covered delivery of the expert-designed workout plans across styles and durations, the progress and session state that has to survive a phone being closed mid-workout, and the subscription flow the business runs on. Stack: Android, Node.js, iOS, backend.

The Shred platform, developed by CodigoDelSur, clearly charts weight, reps, and personal bests, showing user progress.
CodigoDelSur built Shred for results-oriented individuals, transforming effort into measurable fitness outcomes for millions.

The result

Partial third-party Android code was taken over and carried through to release within an eight-month engagement in 2020. Shred has since been featured in Business Insider and in Goop. Rescuing and completing other teams' codebases is a pattern that repeats across the CodigoDelSur portfolio, in Etch, HeyConnect and Taste as well.
