Excellent

I really like the Caliber app. It’s super easy to use and tracks your workouts and nutrition. I like having weekly calls with your coach and the additional support. I highly recommend Caliber.

Highly recommend!!

I have the premium/coaching version of the app & I’ve really enjoyed my time working with my coach Kirsten! She’s taught me so much & answers all of my questions thoroughly & thoughtfully. She is very knowledgeable on both exercise & nutrition which are both important to my goals. The video chats are very helpful as well. They have great flexible renewal options after the initial 3 month coaching period which I will likely use in the future once I make some more progress on my own. The tracking functions on the app are super helpful as well which I will continue using after my coaching subscription ends.

Definitely not free

Per the add it’s free when I download it was actually only a free trial. The price is not that bad so I signed up for the free trial just to check it out and see if it’s worth it. When I clicked free trial it immediately charged me $19.99

Caliber: Strength Training

This app is free! I put in my workout regime, it remembers and tracks everything I input.

Ideal for Anyone

I’ve been working out for the better part of 17 years and since having children struggled to get my weight back under control, manage a consistent workout routine, and set up macro targets that would support my goals.

Caliber did all of this with ease. They helped me lose weight, gain confidence, and establish my routine.

Admittedly this is not a cheap service. I was forced to cut them because of financial constraints. But my time with them was highly valuable and I have no regrets for it.

If times were different I’d wish to complete the program and my goals with their support but the rest of my journey is in my hands alone. I still use the free services in the app to keep track of my progress.

Give them a shot. You won’t be disappointed.
