more This is going to read like one of those reviews that makes you go “yeah whatever heard it a million times” but I’m telling you, I’ve tried other gamified health apps and they’ve never given me the dopamine boost that this one gives me. I got this app in hopes I’d stick to it in preparation for a trip in a few months that I wanted to shed a few pounds for. My self confidence was at an all time low. Now, I’m finally shedding weight that I’ve been holding onto for years and I still feel motivated to continue. PLUS Im doing better than I ever thought I would with showing up for myself and my health CONSISTENTLY. Im someone who doesn’t ever do things for themselves. I find that it’s hard to feel motivated when the only benefactor is myself. HOWEVER- I’m actually emotionally invested in my otter and making sure he’s proud of me. If you relate and also find it hard to do the thing for yourself- this is such a great app.I do hope they add more customization to the otter creature or even add a habitat to customize because the completionist in me craves the ability to continue unlocking things and leveling up.10/10 best decision I have made this year

Like others have said, the system used to input foods for the day needs improvement. There should be a way to correct barcode scans that were put in incorrectly, for the sake of overall improvement of the food library. The AI food scan is an interesting concept in theory—though not always accurate, I still try it first when eating something I don’t have the nutritional facts for and it is less intimidating than guessing from scratch. Last, the otter is…a little annoying to be honest. He is cute but so far I have yet to fully satisfy him. He always finds something to pick on, even if my whole day of eating is excellent. If I have him analyze just breakfast and he says it’s great, later when I have him analyze the whole day if the rest of the day is good, he’s circle back around into criticizing breakfast. I hold they fix this in the future…At first I was impressed by his ability to somewhat hold a conversation, but the longer I talk to him I realize he doesn’t really have access to any of the data in the app.

I got my first Apple Watch and this is the best app in terms of checking sleep and sports but there’s a big issue now. It doesn’t sync well with Apple Watch for sleep duration. The sleep duration on the Apple Watch OtterLife app basically shows the same time as the time on Apple health app(but always 2 mins shorter but acceptable) . However the sleep duration on the iPhone OtterLife app show much shorter time. So iPhone OtterLife app is not accurate because it doesn’t sync well with Apple health. This happened because I briefly woke up at 7 o’clock and then I went back to sleep at 7:15. But OtterLife app shows the woke up time. 7 o’clock soso he doesn’t sync the additional one hour sleep after 7:15. The reason this is a big issue is because incorrect sleep duration caused the incorrect average sleep time and total sleep time, etc. Please fix it. Thanks. And if possible add the total calories on the app.
Developer Response We’re sorry to hear about the sleep sync glitch, we’re already looking into this. Reach out to us at otterlife@iftech.io for more details, and we’ve noted your calories request too.

This app is beyond convenient and it makes all my health information so easy to understand!! I highly recommend this app Ive been using the free version for awhile to make sure the app was what I was looking for and the free version is really great and I feel like the premium version is prived really well! My only complaint is that whenever I try to enter in a custom drink the calories and sugar tweak and are in the 1000s of g when theyre only supposed to be in the 10s or 100s so thats been frustrating but other than that i love the sleep reminders and the time to eat reminders because Im someone who tends to forget until im starving and then i eat way to much.
