HeavySet: Best Workout Log App​ (iOS Only)

HeavySet workout log app
What we like
  • Data entry works fluidly.

  • Can specify intensity and rest time per exercise.

  • Imports as well as exports data.

What we don't like
  • No plate calculator.

  • Only a basic set of exercises included; no descriptions or images.

  • No Android version.

When you ​open HeavySet, which is available only for iOS devices, you'll find an excellent, well-thought-out fitness-tracker app.

Data entry is easy, with well-placed buttons that are big enough not to miss even with shaking legs or hands. Typically you'll have to tap only once to log a set, with HeavySet's smart predictions doing the, uh, heavy lifting.

​HeavySet's smarts don't mean you give up any control over setting up routines. Enter routines as they work best for you. Specify rep ranges, pick weight based on intensity (in percent of your calculated 1 rep max), or define supersets and giant sets. (Drop sets are a notable exception.)

Swapping exercises that target the same muscles is easy, but you can also customize each workout freely. Fitbod comes with a big library of exercises that includes descriptions and videos with proper form.

Fitbod isn't really free. New users get a free trial to use the app for a specified time period and will automatically roll over into a subscription once the free trial has expired.
