How Does Biceps Work?

Biceps is not just another fitness timer; unlike many fitness apps, Biceps lets you focus on your workout, without distractions. It doesn’t tell you what to train and how to work out, because you already have a high-intensity interval training (HIIT) strategy. Biceps is the perfect tool to help you stick to the right intervals between sets and exercises.

Getting started only requires two steps:

  • 1. Define rest intervals between sets and exercises.
  • 2. Start your workout.

After your workout is complete, open the widget on the iOS Today screen to see your stats.


Biceps is a practical and efficient tool designed to help you master the task of working out.

  • Speech Recognition

    Keep both hands free. You can lock your iPhone and use your voice to switch between sets, exercises, and rests.

  • Built for iOS

    Add Biceps' summary widget to the Today screen to see a short summary of your training. You can choose between different timeframe views and see useful stats about your sets, exercises, and workout duration.

  • Training Coach

    Choose between professional voice artists or simple sound effects to let Biceps guide you through your workout. With the added speech recognition ability, it's like having a personal coach at your side!

  • Protein Reminder

    A healthy and effective HIIT session doesn’t end when you finish working out; it’s important to consume protein an hour after your workout is complete to refuel your body. Biceps' handy Protein Reminder is built with this in mind.

Apple Watch
