StepSwitch is a timer built specifically for step-up (bench stepping) workouts. With a regular timer, it's easy to lose track of which foot you're stepping down with — and end up overusing one leg. StepSwitch reminds you to switch your leading foot at the interval you choose, with sound and vibration, so you keep your workout balanced without watching the screen. WHO IT'S FOR - Anyone doing step-up exercise at home - People who want easy, sustainable cardio for weight control and health - Anyone who wants to avoid favoring one leg - People who stay motivated by tracking their workouts FEATURES Step-up workout timer Set any duration from 1 to 60 minutes. The remaining time is displayed large and clear, with one-tap pause and resume. Even if you close the app or turn off the screen, switch reminders arrive as notifications. Foot-switch reminders Get notified by sound, vibration, and on-screen cues every time it's time to switch feet. The app even suggests starting with the opposite foot from your last session. Automatic calorie estimates Calories are estimated from your weight, step height, and intensity — see your effort in numbers. Records and stats that keep you going Every session is saved automatically, with room for notes. Check this month's workout count, total time, calories, and your current streak at a glance.
