StrengthMark takes the guesswork out of planning and tracking your weight training. Be certain about hitting new personal records, loading the barbell, and how you spend your time in the gym. StrengthMark is made for lifters, whether it's powerlifting, strongman, olympic weighlifting, general strength training, or bodybuilding. Here is how StrengthMark helps you: • AUDIBLE REST TIMER - Starts when you complete a set to match your planned rest time. Use the full screen rest timer to watch the countdown while you're on the lifting platform. • HUGE EXERCISE SELECTION - Create your own or choose from over 900 different exercises for strength training, conditioning, mobility, powerlifting, strongman events, and Olympic lifts to build your workouts. • WEIGHT PERCENTAGES - Use sub-maximal percentages to plan and scale your workouts. • CUSTOM TEMPLATES - Create templates based on existing workouts to repeat and scale a series of workouts. • GIANT SETS - Use giant sets and supersets to add another dimension to your training. • PERSONAL RECORDS + HISTORY - Review your personal records using weights and reps of your favorite exercises like the deadlift, squat, bench press, snatch, clean and jerk, Atlas stone load, and more. For each personal record, you can view the full history of past PRs to get an idea of how you’ve been improving over time. • ONE REP MAX CALCULATOR - Use the one rep max calculator to establish a baseline for a training program.

Verdict

The call

The clearest difference is in-app purchases: StrengthMark at none against Intensity's 3. StrengthMark also leads on review sentiment (92% vs 64%) and iOS requirement (13.0 vs 15.6). Intensity's advantage is update cadence (every 4 weeks vs every 3 months) and ratings volume (180 vs 15). On price, rating and ads there is nothing between them.
