You have plenty of fitness apps to choose from to track workouts on your phone, but if you just want to log your steps over time, then give StepsApp a shot.

The freemium app for Android and iOS presents the steps you’ve taken and the distance you’ve covered in a clean and readable way.

If you’ve got wifi problems, or want to make sure you avoid them, then WiFi Analyzer for Android is the free tool for you.

If you’ve got a guitar, bass, ukulele, or other string instrument to tune, then the freemium GuitarTuna for Android and iOS is the single-purpose app you need.

While you can use the default Camera app for Android or iOS to scan QR codes, the freemium ShopSavvy app for Android and iOS gets the job done quickly and throws in a few extras, too.
