Tap “+ Add Task”, give it a title and optional description and due date, then optionally link it to inventory items (so completing it can update their stock) or records (for reference only - this doesn't change the record).
Toggle Recurring, pick a Frequency (Daily / Weekly / Monthly / Yearly), and set how often with Repeat Every - e.g. every 2 weeks. Completing a recurring task automatically advances it to its next due date instead of disappearing; one-time tasks are marked done and archived.
Switch views at the top of the page. Calendar view lays out each recurring task's upcoming occurrences across the month - tap Today to jump back to the current month.
When a record (passport, MOT, insurance, and so on) enters its reminder window, Oiko automatically creates a one-time “Renew [title]” task here for you - no setup needed.
Open the filter menu and tap Sync Calendar for a personal subscription URL. Paste it into Google Calendar or Apple Calendar/iCloud once, and your tasks - including future recurring occurrences - show up as calendar events automatically, staying in sync as you add, complete, or reschedule them. Available on every plan.
