This is an app for those who don’t want to use Apple’s built-in health options while also wanting to save some battery life. Using the updated processors in the iPhone 5s and later,
ActivityTracker tracks your steps, distance, calorie burn, active time spent, and even stairs climbed all on the app on your iPhone.
It doesn’t require GPS to track all these things, thereby saving battery life. It has the handy option to import all your current Apple Health data should you want to switch and also has Apple Watch compatibility, but you don’t need a Watch to use the app on your phone.
The interface is clean and clear and will help you set achievable goals for fitness without the need to fork out for a wearable device. Advanced features are only £2.99 as an additional in-app purchase – well worth the spend.
