To use WriteMapper on your iPad or iPhone device after the limited-time trial expires, you’ll need to make an in-app purchase from within the app, which you can access by tapping on the grey button in the bottom-left of the screen while the app is open.
Due to the way the App Store works, there’s no way to bundle Mac & iOS apps together into a single purchase. Copies of WriteMapper on desktop computers and iOS devices need to be licensed separately, as Apple requires the purchases for any iOS apps to be made through Apple’s own App Store mechanisms.
Further to that, the iOS versions of the app had to be rebuilt from the ground up in order to be workable on the iPad and iPhone lineup of devices, so it's also a separate price to subsidize the costs of additional development.
When this in-app purchase has been made, you'll get full access to the WriteMapper app, even after your trial period has ended. This one-time payment in-app purchase can also be restored on your other iPad and iPhone devices respectively.
Licenses for copies of WriteMapper's macOS and Windows versions running on your computer, on the other hand, can be purchased directly from the store page on our website. This will give you a license code which you can key into your copy of WriteMapper on your desktop or laptop machine. More info on purchasing from our store page may be found here.
