Developer Response Thanks for your feedback, and sorry for the frustration here. That’s definitely not the experience we want you to have. Logging should work without any issues, so something clearly went wrong. I’d really like to help you get this sorted quickly. Could you reach out to me directly at bradley@mavr.app? If you can share what you were trying to log, along with your device and iOS version, I’ll look into it right away. Appreciate you flagging this.

I tried using different apps to know what to eat for my marathon training, however none seemed user friendly when it comes to adding what you eat. Mavr seems to have what other apps are missing, and calories/macro recs are pretty close in comparison. Also, customer service is incredible. I’m highly impressed and will continue to use Mavr for my fueling!
Developer Response Thanks so much for the kind words! We built Mavr to make fueling for training easier without making food logging feel like a chore, so it’s great to hear that the experience and recommendations are working well for you. We really appreciate your support, and we're excited to be part of your marathon journey!

This app is glitchy, and currently not usable without pro even though it seems like pro should be unlocking extra features. I like the idea, the suggestions seemed solid during my free trial but the subscription is too expensive for something in beta and it’s difficult to give feedback.
Developer Response Thank you for taking the time to leave a review. I’m really sorry you ran into these issues. We’re working hard on improvements and several fixes are already included in the latest version.If you still notice anything that isn’t working as expected, I’d love to help you personally. You can reach me directly at bradley@mavr.app and I’ll make sure we look into it together and get it resolved.
