Another vote for "offline access"
This app is amazing, but I can't use it because you require an internet connection just to log in.
I HATE subscriptions, but this is one I would gladly pay... If you worked out the ability to use it offline.... Preferably with my frequently used foods available and then it would sync everything back up next time I connected.
Anyway, really impressive. I'll keep an eye for future development. Best of luck.
