Widgets freezing

Will you please fix the widgets. In the new iOS version it's always frozen, doesn't update until you click it, but even then stays frozen.

Developer Response ,

Hi there - There was an issue introduced by Apple's release of iOS 16. This issue affected multiple developers with the same type of widget as Zero. If you've not already done so please update to Apple's latest operating system (iOS 16.1). If you have already updated to iOS 16.1 and the issue with the widget is still occurring please contact us at support@zerolongevity.com with the details and our support team will assist. – Team Zero

Great but…

The App is great. I would find very useful to be able look at the graphs in a “landscape mode” so when I rotate my iPhone there is much more to see and it’s more clear. Native app for iPad or Mac (or just website) would be great for reading the data (I understand that iPhone with Apple Watch is the most useful combination for measuring and it’s great but I don’t think I have the best tool to read the data).

Great concept bad realisation

I was trying a few apps around to monitor my intermittent fasting. That popped as the best. I liked the idea of a widget. Than I need to register to try it ok? Ooook spending some more time pairing with Apple Watch. And in the evening to find out it want to connect to iPhone in order to click fasting button ? Common guys are you serious. And if I forgot the iPhone or the battery is dead ? Anyway I tried a few apps and simple app looks and gives at least for me better functionality.

Developer Response ,
