Strong is a focused strength-workout logger. PrepAI is a broader local-first wellness tracker that includes workouts alongside meals, sleep, hydration, body trends, and daily guidance. Choose based on whether depth inside the lifting session or context around the session matters more.
Quick verdict
Choose Strong for fast set logging, templates, custom exercises, supersets, RPE, timers, progression charts, measurements, and CSV export.
Choose PrepAI when workout history should inform a private daily plan together with recovery and meal context, without creating a PrepAI wellness account.
Workout depth
Strong is purpose-built for weight training. Its official product and help pages emphasize set types, custom exercises, supersets, rest timers, personal records, body measurements, and progression charts.
Strong accounts and workout tracking are free. The free tier is limited to three workout templates. Strong PRO adds unlimited templates, all charts, body-part measurements, and plate and warm-up calculators.
PrepAI records workout type, duration, effort, notes, selected exercises, recent sessions, and weekly activity. It is useful for connecting the session to sleep, hydration, meals, goals, and a check-in, but it does not claim Strong's lifting-specific logging depth.
Accounts and cloud storage
Strong supports iPhone, Android, and Apple Watch. It describes workout history as stored in Strong Cloud, and its privacy policy says user information may be stored on servers in the United States and other countries. Its Android privacy documentation separately says Health Connect data received by Strong is kept locally; that does not mean all Strong account data is local.
PrepAI keeps core wellness records in its local app database and supports manual encrypted backup. Its current public release is iPhone-first and has no web dashboard or automatic PrepAI cloud sync.
Broader health context
PrepAI adds meals, hydration, sleep, body trends, Apple Health context, deterministic daily guidance, and supported on-device AI. Strong intentionally stays closer to the gym log.
That focus is an advantage if you already have separate tools for nutrition and recovery. PrepAI is more useful when you want one timeline and accept less lifting-specific specialization.
Social and coaching
Strong is a personal training log rather than a social network or remote-coaching platform. PrepAI is also private and personal. Choose a coach-oriented cloud product if shared programs, messages, and trainer review are essential.
Who should choose which?
Choose Strong when the quality and speed of set-by-set lifting records dominate the decision.
Choose PrepAI when strength is one input to a broader local wellness plan and accountless privacy matters more than advanced lifting charts.
