About

Planiko

Read full description

Planiko helps you run your day right from your iPhone calendar. It doesn't replace your calendar: it works on top of it, including the Google or Exchange accounts you've added in iOS. No new account, no extra sync, and your data stays on your device. MAIN FEATURES • Check-in and check-out — One tap when you actually start or finish something, and the event's times on your calendar are updated for real. • PLAN — One tap reorganizes the rest of your day by priority, preferred time window and deadline, with no overlaps. Events you lock stay where they are. • NIKO — Create events fast, with title, time and duration, plus priority, time window and deadline for PLAN. • Gaps and overlaps — See the free time between events and what overlaps. Tap a gap to create an event that fills it exactly. • Travel time — Planiko tells you when you need to leave, not just when the appointment starts, and opens Apple Maps or Google Maps. • Postpone fast — +1h, +2h, tomorrow, a custom date and time, or "skip all" when the whole day slips. • Pause and resume — Check out of what you're doing and instantly create the same event starting now. • Ask for an event — Send a link ("when are you coming to visit?"). The other person picks the date, even without the app, and the event lands in both calendars. • Import from clipboard — Copy a list of tasks and Planiko creates one event for each, in sequence. • Countdown, widget and Apple Watch — Always know how long until the next thing. Works with Capta, the GTD app by the same developer: give a Capta action a date and it appears in your calendar; complete it in Planiko and Capta updates by itself.
