Full screen ads ruin it all I've been using this since it was just "business calendar". It was still $7 back then so I wouldn't buy it but would click the ads every now and then. Now with the full screen ads it's practically unusable. Also, before the dev comes in with the stock "the free version has ads" response: no duh it has ads. We didn't pay for the app because its upfront cost is too high so we liked the corner ads. Now you force them to take over our screens. Uninstalled and 1-Star.
