Im new to Checkmark 2 so I have no idea what 1 was like.
It is quite a nice app, easy to use, nice interface etc.
I only have 2 gripes, one minor and the other a bit more serious.
1. The minor one is that you cant set a recurring item such as: 1st Monday of each month.
2. The more serious one is that with the volume on my phone on full, the reminders are not easy to hear when the phone is in my pocket (which is pretty much where it lives).
