The best thing about this app is its user friendly interface which makes it easy to use even by beginners like me. I have been using this application since last one year now but i am still finding some new features in my everyday usage of this tool so can't say anything negative at all because everything has positive side as well. It's very simple software with an amazing UI/UX design. Nothing much to dislike here if any then maybe their pricing plans are bit too high considering other similar tools available out there. If someone wants something really lightweight than go for Tasker otherwise just stick to Google Calendar or Gmail calendar integration instead of having two separate apps installed separately. We used to keep track of our daily tasks & activities via emailing ourselves reminders from google mail itself. But after getting familiarized with TASKER we realized how beneficial such kind of.
