How to choose

1. Decide what you need most: a record for your appointments, a community, answers to questions, or a diary.
2. Check the price, the platform and the language on the app's own page.
3. Read what it asks of you at sign-up, and what it does with your documents.
4. Try it for a week. Keep it if you still open it.
