Can’t seem to sync with other devices

This app definitely has potential. I started it on my iPad, but I can not get any information to transfer to my iPhone for the life of me. When I try to share it, it doesn’t really do anything but open it on my iPhone. Other than that, it is a pretty good app. Holds a lot of info.

Responsive developer and great app

I use this app to log all my tanks nitrogen cycle progress and keep track of other parameters. It’s great. Also there was a minor bug in the app and I dealt with the developer directly and they had it fixed within a week. They were communicative and persistent in solving the issue. Well worth the money to have a convienient app like this at my finger tips to track my water parameters and other things. Highly recommended app to enhance the hobby.

Seems great so far

I’ve only been using it for a couple of days but so far I really like it. The only thing I haven’t figured out is how to do recurring reminders. Is that possible? If not, the reminders are less useful. Could totally be user error here.
