Got questions? We have answers.
Can intermittent fasting help me lose weight?
Yes! Fasting alters how often you eat, which helps you eat less without counting calories or going on a diet. Intermittent fasting also encourages healthier, more conscientious choices around what you eat. Finally, intermittent fasting enables your body to tap into its fat stores for fuel so that you burn fat faster.

What a great app! I love how easy it is to visualize where I am in my fasting and how inspiring the extra learning material is. When I'm in the middle of a fast and I start getting weak-willed I am able to use the app to get inspired again and re-motivated to keep going. I am also learning so much about fasting and exercising during a fast that I would never have gotten anywhere else. I paid for the annual subscription and I am so glad I did. It's definitely worth it for me.
pretty great, the issues: 1) long loading of the application, does it sync with the cloud every time you open it or something? 2) how long is it going to take to implement a themed icon, it's so simple
Will not renew. Has the potential to be 5 stars but I'm so frustrated I won't renew. I do intermittent and prolonged fasting. impressive info and tracking. HOWEVER while it tracks my time in ketosis, fat burning etc, saying 'more efficient or less efficient' it doesn't say HOW OR WHY. W/o that info it's useless to me. Good for new fasters not for experienced fasters. Being able to integrate with Oura felt like a game changer. Alas it is not. YAY OURA Meh Zero
Loved this app at first, but features began to be frozen after a month. After starting a fast, I couldn't adjust fast times and goals even after force stopping app and deleting cache. I can't delete incorrect fasts after this, too. i checked for an update, but my app is most up to date so I don't know what's wrong. Will not be reinstalling.
I've been using this app for about 9months and have enjoyed it very much. However the last 3-4 weeks I haven't been able to edit my fasting goal or delete inaccurate fasts. This is frustrating because it prevents my challenges from being met & having an accurate history. I purchased the annual subscription & feel like it's not worth it. I have an open ticket with support which they confirmed its a known issue & are working to fix it but we're going on 3-4 weeks without a fix.
