I've tried a number of other calendar apps and none have the flexibility and customization of Pimlical. This apps fits my calendaring, all others I had to try and adapt my processes to meet the app.
Pimlical/Android - What a calendar app should be I started using DateBk in the Palm Pilot days. On Android, I missed so many features like floating appointments and icons. Armed with Pimlical/A, I've now got all those things.
Loved it on Palm, love it on phones. I started using it on my first pre-phone palm, and have had it on every handheld device since. So helpful and well-designed.
Best full featured calendar app All the features you could want, plus more. As a long-time user of Datebook and then Pimlical, I know it's the best. I've tried everything else. Pimlical wins.
World Class I'm one of the Palm refugees, used the earliest "DateBk" versions up to the current Android implementation. This app was, still is, and is increasingly stand-out among all Android apps (imho), not just calendar apps. It is feature rich, elegantly architected, has incredible number of options & settings, has excellent documentation, is very robust and exceptionally well supported and maintained. Not the most beautiful app, but for the more than casual calendarer, the learning curve is well worth the effort.
