About

Strongbell

Strongbell builds a kettlebell plan around you, shows you every lift and takes you through every set, with a coach who calls out your sets and rests. A PLAN BUILT AROUND YOU Tell Strongbell your goal, your experience, how many days a week and how many minutes you have, and which kettlebells you own, in pounds or kilograms. It builds a six-week program: the hinge and the swing first, then squats, cleans, presses, rows and get-ups when you are ready for them. Finish your sets as planned twice in a row and it offers the next bell you own or more reps, one step at a time. When the six weeks are done, the next block starts denser, with your heavier bells. Reminders on your training days, if you want them. GUIDED, SET BY SET Every workout shows the exercise, the reps and the bell of each set, and times your rests. Log your reps with one tap when a set is done. A COACH IN YOUR EAR The coach calls out every set, counts down the rests with tones and tells you what comes next, over your own music and with your phone locked. The Lock Screen shows the rest counting down, with a button for the set. YOUR OWN WORKOUTS Put together a workout of your own from the exercises: sets, or a circuit done round after round, the way a complex is done with one bell. EVERY LIFT ON VIDEO 23 kettlebell exercises, each with a video from one or more angles and written steps: Swing, Clean, Snatch, High pull, Overhead press, Push press, Goblet squat, Front squat, Deadlift, Bent-over row, Reverse lunge, Thruster, Turkish get-up, Windmill, Halo, Farmer carry, Single-leg deadlift, Floor press, Glute bridge, Cossack squat, Seated twist, Rack carry and Overhead carry. SWING PRACTICES Daily practice (100 swings, 10 get-ups), 10,000 swings, Swing EMOM and Swing ladder. PROGRESS YOU CAN SEE Swings per week, streaks, records, and volume by exercise and by bell. Open any workout to correct it, log one you did without the app, export them all as a spreadsheet, or share one as a picture. Your workouts can be saved to Apple Health. ON YOUR HOME SCREEN Widgets show your next workout and your week, on the Home Screen and the Lock Screen. Ask Siri to start today's workout. PRIVATE No account and no ads. Your workouts stay on your iPhone; the app collects no data. STRONGBELL PRO Strongbell is a subscription: yearly with a 7-day free trial, or monthly.

Verdict

The call

The clearest difference is ads: Strongbell at none against Flexibility & Stretching's shown. Strongbell also leads on update cadence (daily vs every 5 weeks). Flexibility & Stretching's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price and in-app purchases there is nothing between them.
