Great product

The team behind Calibrex clearly prioritizes customer success, providing outstanding support and continuous improvements. It’s a game-changer that is getting better by the day! I use it with every workout and any feedback I’ve provided has been addressed by a real person quickly.

An expensive refrigerator magnet.

Negatives:
1. Reps were almost always off. I kept a log - Sometimes by 1, but often by a larger amount.
2. Battery life was poor. 1 workout and that was it.
3. I submitted 2 support emails, no reply to either.
4. Frequently my workout would reset and get list if I had to reconnect.
5. With no warning, my device logged me out (While offline). I could not recover my password/log in. Re-Registering worked, but all my workout data is lost.
Positives:
1. The magnets are very strong and even hold on dumbbells nicely.
2. The charts/graphs produced are nice.

More customization needed in workout plan

I want to give feedback on the exercise feature in the app. Currently, the app's exercise tracking is limited and inflexible. It follows a very linear sequence, and I find it difficult to adjust the order and sequence of exercises or add/remove reps based on the availability of gym equipment. It would be helpful to have the option to make these adjustments for a more personalized and adaptable workout experience.

S&C Perspective

Really wanted to love the device but just not accurate. I loved how mobile it was with just the magnet or wristband. However, it would typically miss half my reps on every exercise :(. Customer service was great and pushed out more updates to try to correct. Unfortunately it just didn’t get the job done, but they were great and refunded upon return. So instead I doubled the price and went with the Flex which is 100% accurate but not as mobile as only tracks barbell exercises. I see the potential here, it’s just not there yet!

Super pricey device
