FAQ
How does Phase adapt to my fitness level?
Phase offers personalized 'Journeys' that suggest manageable run/walk intervals based on your feedback after each session. If a workout is too hard, it can offer a gentler option, or if it feels right, it can suggest a small step forward.
Can Phase guide my workouts without me looking at my phone?
Yes, Phase provides spoken cues and countdowns to guide you through your workout. These cues can be heard even when the phone is locked and can mix with your existing music.
What types of workouts can I create or use with Phase?
Phase supports a wide range of workouts including HIIT, Tabata, EMOM, circuits, boxing, running, stretching, and swimming. You can build your own custom timers or choose from 28 ready-made workouts.
Does Phase have ads?
No, Phase is ad-free. The app focuses on providing a clean user experience without any advertisements.
How does Phase handle workout progress and streaks?
Phase tracks your time, distance, active days, and completed workouts without the pressure of losing streaks. A rough week won't erase your past achievements, and you can stop early without penalty.
What is the cost of Phase?
Your first 14 completed workouts are free. After that, a one-time payment called 'Phase Unlock' removes workout limits and includes all premium features, ready-made workouts, and journeys. There is no subscription or recurring charge.

Phase is currently supported on iPhone devices. The app is designed to work with iOS operating systems.
