Application is currently not signed so after copying it to Applications folder you'll have to right click on it and select Open (just for initial launch).
But it is fully Sandboxed:
No file access at all
No network connection (not even for analytics)
No permissions (except for optional Notifications)
If you have Xcode, you can also simply clone and build it yourself.
Changes in v1.0.1:
- Fixed an issue where tomorrow's daily countdowns were not appearing if current day also has them
