When iPhone 5s debuted, Apple introduced a new thing in hardware: the M7 coprocessor. It runs alongside the A7, the latest chip that powers your iPhone 5s.
What the M7 did and how it was going to be useful were questions that had only theoretical answers.
But with a few apps using the M7 Motion coprocessor, the power that the additional processor wields is becoming clear. Not to sound “fanboyish” but it’s a huge step forward in battery management for motion-tracking apps.
Argus from Azumio is a health and fitness tracker. It works with a few third-party gadgets and can track a variety of physical activities to help you track, monitor and strategize your fitness routine. It’s a widely popular app and on the day M7 was announced, it became the first app to support the feature. Argus tracks food intake, exercise routines, sleep times, heart rate and more.
#2. Strava Run
Strava Run is a niched app for tracking your runs. It has been around for quite a long time; it’s popular already that it warrants no introduction. Strava Run is a fun app with a large dab of social touch to it. It makes running interesting with goals, leaderboards, maps etc.

This got launched only recently (at the time of writing this). Pedometer++ is ultra-minimalist: it tracks only your steps. Daily and weekly counts are tracked and shown. The app also lets you set it so that the number of daily steps shows as a notification badge on the app icon. Pretty simplistic but good.
So, What’s The Deal With M7?
Battery. That’s what it comes down to.
Before iPhone 5s/M7, apps kept the processor, GPS and motion sensors running in order to track your movements. This eats up a lot of battery. With the M7 in the scene now, the main processor does not do all these things. M7 tracks and keeps information about the movements.
An app that is designed to use the M7 only fetches data from the motion coprocessor instead of turning on and using the motion sensors by itself. This reduces any power consumption caused by the app.
