Yes. No card and no account — you describe a goal, answer a few questions and get a plan. One goal is free, with the first half of its plan in full detail and the outline of the rest.
Pro opens in full for seven days. Cancel in App Store settings before they end and you are not charged; otherwise the plan you picked starts — $4.99 a month or $49.99 a year in the US.
Anything that can be broken into steps: a language, a lift, quitting a habit, shipping a project, saving money. The plan is built around your level, minutes per day and budget. It is not medical advice.
Missed tasks stay visible, nothing is lost. With Pro you can rebuild the plan from where you actually are — new dates, same goal.
No. Everything works as a guest, Pro included. Sign in with Apple or Google whenever you want your goals on another device.
iPhone today. Android is in the works.
