Meticulous Lite is an app for keeping datestamped text notes. There is no way to edit an entry once it’s written—that’s the whole point. If you are an author, inventor, private detective, or anyone else who wants to prove the age of a document you wrote or an idea you had, Meticulous Lite is just what you need.

Entries are also secured with a passcode so that only you can see them. Combined with the built-in security of iPhone OS, your notes will be quite safe in Meticulous Lite’s hands.

Looking for more security? Meticulous Pro registers datestamps of all of your entries with a third party to make them easier to prove. It also includes banking-grade AES encryption to keep your notes safe from anyone who tries to steal them.
