StrengthLog Workout Tracker for iPhone

StrengthLog — Strength Training & Session Recorder

StrengthLog is an iPhone app from Styrkelabbet AB that helps lifters record workouts and follow established strength programs. Built by people who lift, the app focuses on durable logging, progress visualization, and basic-to-advanced performance analysis to support steady strength gains.

Key Capabilities

• Premium users unlock deep analytics and the complete catalog of training plans, plus features like quick set summaries and set-level statistics.
• The free tier lets you record unlimited workouts, monitor simple stats, and keep track of personal bests.
• You can log effort details such as reps-in-reserve or rate-of-perceived-exertion for each set (premium feature).
• Included free utilities cover a set timer, calorie calculators, Wilks and Sinclair scoring, and one-rep-max estimators.
• The app supports syncing of workout data with Apple Health for centralized tracking.
• Several well-known routines are available in the library, for example Starting Strength and the Russian Squat Routine.

Pricing and Upgrades

A subscription option expands the app’s capabilities: advanced statistics, the full suite of training programs, faster set-overview tools, and detailed effort logging. The free version remains useful for day-to-day logging and basic progress tracking, while the paid tier is aimed at lifters who want deeper insight and program variety.

Additional Tools and Integrations

StrengthLog bundles a number of small but useful tools in the app — timers, calculators for calories and strength scoring systems, and simple 1RM predictions — making it easier to plan sessions and evaluate performance without switching apps.

Who Benefits Most

Whether you’re just starting out or you’ve been training for years, the app is suitable for lifters who want a focused strength tracker: novices benefit from structured programs and basic tracking, and experienced athletes can take advantage of the premium analytics and detailed set logging.

Alternative Suggestion
