Best FREE fitness app

This one about the only fitness app I could find that had all the features I wanted for the price off FREE! Easy to follow a trainer’s program tailored to your liking, and you can add/delete certain workouts as needed.

This has been a really great journey!

I have used Caliber in every tier available , from the free version to the live coaching premium, and I cannot recommend it enough! Overall design and features are conducive to beginners as well as persons who have advanced in their fitness knowledge and want greater flexibility and customization in building workouts. I have worked with trainer Jonathan Swenson for a year and a half now. With him I have not only have I accomplished significant body recomposition and strength gains, but I have a knowledge foundation that will serve me for the rest of my fitness journey. This is all a result of Jonathan‘s positive and supportive approach, quick response time, and honest and productive feedback. I highly recommend working with Jonathan Swenson if you go to the premium coaching route! Thanks Caliber and thanks, Jonathan!

Great App

I have been using caliber and it has made my workouts more enjoyable and efficient.

Great coach but meh app

My coach is excellent. I really enjoy that part of the experience. The app, not so much. It’s got lots of oddities that make it feel unpolished. I did take the time to share extensive feedback with them but the company seems focused on big shiny objects instead of quality-of-life stuff that makes day to day use, data entry easier. Before you commit to $4500/year for coaching do your self a favor and play with the app during real workouts, so you can experience the many paper cuts.

APPLE WATCH SUPPORT

Really enjoy this app. It’s super user friendly and I love that most of the features are available without paying for a premium plan. BUT PLEASE MAKE IT SO THE APP CAN LINK WITH APPLE WATCHES. EVEN IF ITS JUST DISPLAYING THE REST TIMER PLEASE 🙏🏽
