The Ultimate 5/3/1 Calculator & Strength Logger helps you plan, log, and progress on 5/3/1, Beyond 5/3/1, and custom 531 cycles. It automatically calculates weights for Squat, Deadlift, Bench, and OHP, provides a Plate Calculator with Kg/Lb support and configurable bar weights, and supports popular templates for flexible progression.

Privacy-focused and gym-ready, this extension requires no subscription, registration, or ads. Features include warm-up sets, a rest timer, and Apple Health integration, plus a 3-week trial with a one-time unlock for 5/3/1 Pro and Assistance Workouts. It’s an independent calculator and log (not affiliated with Jim Wendler) designed to help serious lifters track progress with clear charts and precise plate math.

User Reviews

Users praise the app for solid 5/3/1 support, progression tracking, and a helpful plate-loading calculator, plus timers, easy customization, and good developer support. The Apple Watch extension adds hands-free data entry. Common drawbacks across reviews include data save/reset problems, weight miscalculations across cycles, unreliable watch integration, clunky template editing, and occasional crashes or stability issues. When working well, it’s a powerful, motivating tool for 5/3/1 training, but reliability and editing ease are notable drawbacks to consider.

Pros

Strong 531 program support with guided progression (BBB, FSL) and steady strength gains.
Plate loading feature that uses your real weights to tell you what to load, reducing gym math.
Timers and organized interface with automatic 1RM adjustments help keep training progression on track.
Apple Watch integration/extension allows data to feed from watch for hands-free tracking.
Responsive developer support and ongoing maintenance.

Cons

Data saving and syncing problems: workouts can reset or fail to save after cycles.
Weight calculations and cycle loads can be incorrect, leading to mismatched weights.
Apple Watch integration can be unreliable: the watch doesn’t always recognize a lift or syncs poorly.
Template editing and customization can feel clunky or require a learning curve.
Stability issues: app can crash or randomly close during workouts.
