NIce!

I tried a basic 3-month subscription and really enjoyed the experience. Daily communication with my coach, advice, follow-ups, encouragement, varied programs, attentive to my needs. Thanks Marquez, let's go for another 3 months! :-)

Best fitness app!

I’ve used Caliber for the past 3 years and it’s simply amazing! I appreciate how customisable it is and also very easy to track your progress with the weights/reps history. Another plus is the break timer to keep me on track. I recommend this app to all my friends and family, it’s simply the best! Keep up the good work 💪🏼🔥

Great app to log training. Recommend it.

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!
