We would love Mailtrack to work on your iOS device, but for the moment our Mailtrack Add-on is only compatible with Android phones, unfortunately. The truth is that it doesn't depend on us. Add-on compatibility for iOS depends on both Google and Apple's collaboration.
The Mailtrack Add-on is ready and will work automatically with iOS when those compatibility issues have been fixed, no work is needed on Mailtrack's side. We've been told that Google and Apple are working on Add-ons for iOS, but the release date is still unknown.
We will announce it to all Mailtrack users as soon as we know about it.
