I'm trying to download the software directly to my iPhone instead of my Mac computer/Windows PC

Decipher Tools programs are desktop software that run on your computer. Downloading the program to your iPhone will not work. You need to download the software to your Mac or Windows computer.

If you have never backed up your iPhone in Decipher TextMessage, you will need to do this first in order for the programs to import your messages so that you can activate a device and get up and running with the software!
