wwrite was a plain-text application that allows you to create and save files from templates. wwrite supported iPhone, iPod Touch, and iPad.
wwrite is full of features like templating, emailing, archiving, importing, and exporting files. wwrite does not keep your files on any servers, all of the files are local-only. If you want you can lock the files which will require either Face ID or Touch ID to unlock, which will prevent someone from being able to read your files. You could also select one of 46 different App icons.
Version 6.3.0 adds even more features like redesigned menus, updated change log and FAQs screens, and a redesigned Customize Template screen and even more. Check out the change log
