I lost >10kg

I used Rex to track my calories and get back in shape. I've since lost more than 10kg. The experience is great and I highly recommend trying them out.

The calorie logging is 🔥

The calorie logging feature on Rex is great. I'm never going back to MyFitnessPal.

I can finally track my own workouts

I've been looking for something I could just tell "I did 3 sets of 40 pushups" and it would just track it for me. The benefit of having my workouts and meals in the same convo on my phone is great. I also love the automated daily reports.

It really feels like a personal coach

I've struggled with accountability my whole life. It's been hard to stick to a meal plan or a workout app. The fact that Rex texts me daily gives me the push I need. I text it all the time, even when I haven't worked out. Knowing that I will see what I ate in the report card at the end of the day keeps me from binge eating like I used to.
