I'm pleased to announce that v5 of the iOS, Mac and Windows apps are now live (there wasn't a v3 and v4 of the Windows app - you didn't miss anything!)
The headline feature for this release is Encrypted, Password Protected maps. You can now assign a password to a map and the resultant ITMZ file will also be encrypted using AES-256
This means that you can email your ITMZ files and be sure that no one can read the contents without knowing the password. It also means that you can keep your most secret plans in systems like Dropbox without fear of prying eyes.
Encryption is available on all 3 platforms (Mac, iOS and Windows.)
You must remember your password. There is nothing I or anyone else can do to recover a map without knowing the password.
Please see here for more details.
As part of the work to support encryption, the whole (iThoughts) file system (on iOS) was updated. A by product of this is that it now works much better with the built in Files app.
As always, I also discovered and fixed a ton of bugs on all 3 platforms. Any questions, suggestions or issues just let me know.
