On iPhone you can use Planzer with Siri and the Shortcuts app, without opening Planzer.
Ask Siri
Say one of these:
“Add a task in Planzer” or “New Planzer task”. Siri asks what the task is and adds it to your Inbox, or to today’s plan if you choose Today.
“Start my next task in Planzer” or “Start the Planzer timer” starts the timer on the next open task on today’s plan.
“Stop the Planzer timer” stops the running timer.
“What’s left today in Planzer” tells you how many tasks are left today and what’s next.
Use the Shortcuts app
Open the Shortcuts app and search for Planzer to find Add Task, Start Next Task, Stop Timer and What’s Left Today. You can add them to your own shortcuts and automations, or to the Action button on iPhones that have one.
Good to know
You need to be signed in to Planzer on your iPhone for the shortcuts to work.
