### 5/5 — Excellent

*2026-08-12, version 5.15.1*

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.

### 5/5 — Highly recommend!!

*2026-08-11, version 5.15.1*

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.

### 1/5 — Definitely not free

*2026-08-07, version 5.15.1*

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

### 5/5 — Caliber: Strength Training

*2026-08-05, version 5.15.1*

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

### 5/5 — Ideal for Anyone

*2026-07-30, version 5.15.1*

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.

### 2/5 — It’s okay

*2026-07-28, version 5.15.1*

Free version is okay but you really can’t do too much at all with it without the premium version. Probably be better off just googling some plans if you don’t want to pay. Not bad though

### 5/5 — Great App

*2026-07-27, version 5.15.1*

The app is designed for beginners all the way up to advanced. The overviews are extremely helpful and the information the app provides is excellent and easy to follow.

### 5/5 — Great Experience

*2026-07-21, version 5.15.0*

I chose the middle tier, and I was thrilled with my experience. I worked with Grant Slama. He was very encouraging. He communicated well and laid out the plan clearly. The app is easy to use and makes it nearly impossible not to achieve your goals. I hope to renew in the future.

### 1/5 — Scam likely

*2026-07-18, version 5.14.1*

It’s not free like they said it was In The ad

### 4/5 — Not for me

*2026-07-15, version 5.14.1*

I’ve been working out for about 10 years now and never tried an app so this was my first experience and I really didn’t like it. It’s so overly complicated. I am only in my 30s so I know how to use a phone but I was basically spending half my workout messing with the app, it was really wasting my gym time. Have you ever heard of cognitive overload? So overwhelming all the different screens, buttons, small fonts at time. Didn’t work for me at all and their contact us button didn’t work either so I couldn’t even get help. Canceling my free trial now. The app itself is built really well, great job developers. UI/UX could use some work
