|---|---|---|
| Value for money | APro is $5 a month paid annually or $6 monthly, well under the $8 or so planners usually start at. It adds multiple calendar accounts, recurring scheduled tasks, the Ask Trevor chat and progress insights. The site says the price shown may include a 25% sign-up discount. | BBase is €9.99 a month, or €8 a month billed annually, about what planners usually cost, and it covers up to 5 users and 3 workspaces. But voice input, the headline act, is capped at 30 minutes a month on Base, and the booking link needs Advanced at €15.99. |
| Free plan and trial | BThe free plan covers the Task Hub, the calendar planner, unlimited task scheduling, Focus Mode and AI slot suggestions, for personal use. But it connects one calendar account, automation is limited, and recurring scheduled tasks are Pro. Work and home calendars on separate accounts? That's a paid job. | DNo free plan. Every plan has a 14-day free trial, but you enter payment details at sign-up. Nothing is charged during the trial, and after it you need a subscription to carry on. |
| Features | ADrag tasks onto the calendar, let the AI predict durations and suggest slots, or hit Plan My Day for a draft you accept in bulk. Focus Mode breaks a task into five steps. Todoist, Google Tasks and Microsoft To Do sync both ways, and hour reports export to PDF. | ASpeak a sentence and it becomes a task with a time and a priority. AI scheduling finds each task a slot and replans when the day changes, notes turn into tasks, and a master calendar pulls every workspace into one view. Advanced adds a booking link that shows only your free slots. |
