Fantastic

This is exactly what i needed. i love using this app, BUT the icloud sync across iphone and macbook does not seem to work. As I use it i feel that I’ll think of some improvements since id be using it every day, but this is a game changer for me

Response from developer

Thanks! You were right, iCloud sync was broken. It's fixed now, so update to the latest version and it should sync between your devices. If it still doesn't, email me at info@smartkiitos.com. I'd also like to hear those improvements when you have them.
