JEFIT makes it easy to develop and keep a gym routine. I definitely have noticed results using this app. Whenever my routine gets a little stale I add in a new exercise with ease. I have had no issues with the updates, in fact the ability to lock the screen in the app was a welcome addition.
If you are a beginner or finally heading back to the gym I highly recommend this app.
