Agree with others. Was good but the full screen ads are becoming tiresome, especially when you cannot close them and they pop up in the middle of appointment making. In all it's pointless as a calendar and I'm getting frustrated - I've had this one years across several phones. Likely to uninstall as soon as I've found a calendar that does what this used to do so well to replace it.

Until a week or two ago, Business Calendar was the best free Android calendar. But, since the latest update, it displays noisy full-screen adverts in the middle of a quiet office, and disables my Home and Back keys so that I can't stop them. This is half a step away from malware. I'm now looking for a new calendar. I think I've settled on aCalendar. It's a pity; I haven't found a replacement that's as good as Business Calendar used to be.

finally HAD to uninstall this application due to the never ending advertising every time you either open or make alterations to your diary and recent request received.. i.e. required! to send me more ads from even more clients. very much a shame as I've used this application for many years and it's easy to use but certainly am not paying £5.99 to go ad free. the paid version 'appears' to offer lots more.... lots more of what you don't really need.
