Deep Dive: Switching from Strong Pro to LiftLog

Trade-offs, installation & data architecture

The Catch vs Strong Pro

What you trade away

LiftLog covers sets and routines but lacks Strong's mature Apple Watch workflow, broad platform polish, exercise library, chart depth, and long-refined template editing.

Installation

How to deploy LiftLog

Install the iOS or Android app from an app store

Data Ownership

Where your data lives

Workout plans, exercise history, sets, and measurements are kept on the device and can be exported as plaintext; optional social/backup features publish encrypted data through the project's backend.

Build vs Fork Verdict: YES (the core loop fits in a weekend)

Why fork LiftLog instead of vibe-coding a Strong Pro clone?

The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Strong Pro, log workouts, templates, sets, rest timers, and personal history locally. The hard boundary is mobile polish, widgets, watch app, cloud sync, and exercise database, plus hardware data, content, coaching, and trust.
