I am so impressed with the ability of this app to recognize food and quantities whether it be from text, picture of a brand product packaging or a plate of food. It’s giving me valuable feedback on an entry by entry, and total daily consumption basis of GL, calories, protein, etc. it even suggests healthier alternatives. I thought from the app description that there would be a way to view trends / chart. But I can’t find it. That would be helpful to have. I think it would be great to have a way to also log/connect to apps with weight info. So the correlation between weight and food / GL can be seen. And there needs to be a way to add something that you do every day /frequently easily. For example, coffee with coconut milk. Right now this must be added manually each time. If there were a personal history from which to draw that would make entry easier. There needs to be an easy way to sync data from phone to iPad and vice versa. I can’t find it so am limited to using the app on my iPhone. I’m paying for the annual subscription anyway and hope to see some of these suggestions in an update soon

Thank you so much for the kind words - I’m doing my best to make sure the app works as smoothly and helpfully as possible.Trend tracking has just been introduced in version 1.6.0 under the name Habit Compass, and it’s only the beginning. I’m very eager to hear what users think, and I plan to keep improving it.Integration with Apple Health and other data sources is definitely on the roadmap, but I don’t have a release date yet.You’re absolutely right about manual meal entry - it’s not ideal right now. In the next update, I’m planning to add suggestions based on your recent entries to speed things up.As for syncing between devices, it’s been on the roadmap for a while, and your review gave me the final push to finish it. I’m happy to share that full sync launched in version 1.6.0.Thanks again for your thoughtful feedback - it really helps me shape the future of the app.
Good app, user friendly

Been happy with the app. I had a weird, complicated technical issue and the support was great and fixed everything. Thanks Jerzy!
Developer Response
Thanks so much for the shout-out! I'm really glad I could help resolve that technical issue for you and that Logi is proving useful. Hearing it's user-friendly means a lot, as that's always my goal. I'm excited about some new features coming soon too!
This is a great app

I have been using this app for a few months. I have enjoyed using it to track my eating habits to maintain improved blood sugar. The last major update broke it but the developer was very responsive and the patch went out as fast as Apple would process it. I was impressed by how quickly it was addressed. I should use this app for a long time.
Developer Response
Thank you so much for your feedback - and you’re absolutely right, there was a bug after the last update that caused new scans to be saved under an earlier day instead of the one you selected. As a result, it looked like the app wasn’t saving or calculating your meals.The issue has been fully fixed in version 1.6.15, which is already available on the App Store.This was our biggest update so far, and while that’s not an excuse for the confusion it caused, we’re really grateful for your patience and for using Logi.Please try again after updating, and if anything still feels off, you can always reach us directly at contact@logifoodcoach.com.
So awesome love it! 🙌
