## Strengthiness Interval Timer Reviews in United States

### ***** "Simple, effective."
Interval timers need to be easy to read, super simple to interact with while exercising, and flexible enough to handle different workout set plans.  This app hits all three of those points without adding extra fluff - you set up the timer for your set, and focus on the exercise.

Four default exercise modes and a custom setup area, stop watch with lap timer, rep counter with a single whole-screen tap count, it absolutely helps improve my workouts.
