Please allow me to close pop up ads!!!

I would have given this app 5 stars because it's so useful for tracking your cycle. However the latest "update" means that a pop up ad appears each time you open the app. I can put up with this since the app is free. Prior to the upgrade I just tapped x to close the pop up ad and went straight into the app. Now however, tapping x to close the pop up window does *not* work. The pop up ad never closes and you are force redirected into the apps store for the popup (which is usually some stupid game or other). I would imagine that like me most women password protect the app for privacy regarding their cycle. This means that in order to get into this app I have to go through several frustrating steps - ie open the app and enter my password, get the popup ad onscreen, try to close ad, shout at ad as I'm redirected to iTunes, close iTunes, reopen 'My Days' app, enter my password AGAIN, and finally get into the app. It is beyond frustrating and while the app itself is great, getting in is so annoying that I cannot recommend it to anyone unless this issue is fixed ASAP!!!

Annoying adds

I actually paid for the pro version of this app to avoid the adds that were driving me crazy. Sill things popping up on it to ask for reviews and data backups. These things pop up over the information your trying to see.

Simple, easy to use, brilliant

This app is great. Easy to use, simple, allows to intuitively edit, add or remove info, does not annoy you with adds.

One really welcome update would be for screen rotation, as the app only displays vertically, which is a bit of the nuisance for iPad users who do most of their work on horizontal screen.

Anyhow, greatly recommended.
