Mac: Slick, intelligent calendar tool Fantastical is normally a bit pricey at $21, but it's currently on sale for $10.49, and one of our favourite password managers, 1Password, is also discounted to $26.
The Fantastical sale is good until February 14 (there's an iPhone version available for $5.49). The 50 per cent off sale on 1Password has no definitive deadline, though it says it's for the Mac App Store Productivity sale, so it too may end on Valentine's Day.
Both apps are well loved for their rich features and usability. Fantastical lets you create events from the menu bar using natural language, while 1Password securely stores all your passwords, credit cards and notes. If the hefty prices kept you away before, now is the time to give them a shot.
