Looking for a free Strong alternative without the 3-routine limit?
Strong is a fast, well-loved gym logger, but its free version stops at 3 routines and more routines need a PRO upgrade. PersonalBestie gives you unlimited routines, instant guest logging, and AI coaching recaps—completely free and open source.
Local-first in your browser. No credit card, no app store download required.
Why lifters switch from Strong to PersonalBestie

5 Reasons lifters prefer PersonalBestie
No 3-routine limit
A Push/Pull/Legs split already uses all three free slots in Strong, and Upper/Lower or a 5-day program needs more. With PersonalBestie every routine you create is saved, with no upgrade prompt when you add a fourth.
Grounded AI workout recaps
Logging sets is only half the battle; knowing what to do next time drives progressive overload. When you finish a workout while signed in to PersonalBestie, an automated AI recap highlights new PRs and volume changes and reads your notes (e.g. "felt shoulder twinge on set 3") to give practical, grounded feedback.
Zero-friction guest logging
PersonalBestie runs in your browser with local IndexedDB storage. Open it, log exercises and weights as a guest immediately, and when you're ready, one-click Google sign-in syncs your existing data.
Custom exercises beyond lifting
Your training does not have to fit a fixed exercise library. Create your own exercises and activities, including cardio and bouldering, and include them in your routines and workout log alongside strength training. Use notes to add context about the session.
Connect your own AI with MCP
PersonalBestie exposes Model Context Protocol (MCP) endpoints. Connect Claude Desktop or another AI assistant directly to your workout history, analyze long-term trends in natural language, or draft training blocks from your real logs.
When does Strong still make sense?
We believe in honest comparisons. Strong is a mature, popular app, and there are situations where it might still be the better choice for you:
Frequently asked questions
How do I switch from Strong to PersonalBestie? ↓
Open PersonalBestie, go to the Routines tab, and recreate your routines with fast exercise search, or paste your workout notes into the AI chat and let it parse and save the routine for you. Strong can export your history as CSV, so you can keep your old data for reference.
Is PersonalBestie really free compared to Strong? ↓
Yes. PersonalBestie is an open-source project. Unlimited routines, workout history, PR tracking, and routine sharing are free, with no trial period or routine cap. Strong's free version limits you to 3 routines and offers PRO for more.
Does PersonalBestie have an Apple Watch app like Strong? ↓
No. PersonalBestie is a responsive web app (PWA) for phone, tablet, and desktop. If logging directly from a watch is important to you, Strong's Apple Watch app is a strength.
Does PersonalBestie work offline in the gym? ↓
Yes. In guest mode, all your training data is stored directly in your browser's IndexedDB storage. You don't need a reliable gym Wi-Fi or cellular connection to log your exercises, check weights, or view routine templates.
