Who says calendars can't be fun? Vantage takes the mundane out of scheduling. In part because it works well and is easy to use, but also because of useful visual cues like colors, stickers, book covers and stacks. Visual cues makes understanding a long list of stuff easier, and can help you understand your daily life better. Sort of like doodles in a physical book can help you remember notes. Picked by Apple as the "App of the Day" on the App Store in 2019. Stacks Stacks are a really cool way of summarising days. It reduces clutter and visualises how much is on your plate. The higher the stack, the more things you got planned. Tap any stack to peek it’s contents. Integrated To-Dos To-dos live in little notebooks right next to the main timeline. To set a due date, just drag a to-do and drop it on a date. You also get to customise your books with a pre-set book cover, or even a photo from your camera roll. Color Tags and Stickers Visual cues makes long lists of stuff so much easier to read. Pick from a variety of funky stickers or color tags to let events either pop or feel connected.
