Looks like a good idea to me. A bit like ClickUp for private, single user purposes.

My feedback: The app icon looks outdated, which would stop me from downloading it. The widget is confusing. There is no information I get out of this widget which makes no sense to me. The last slide on your App Store Page looks unprofessional regarding to the mockups.

Apart from this, it seems to be a great app with helpful features.
