Ive been a customer for a long time, probably ten years or more, and have used the software on a variety of platforms ranging from a pocket pc to an iPad.
First, all purchases carry over to all platforms. This is amazing, and generous. I wish more publishers followed this example. The same bibles I purchases years ago still work, no extra cost.
The software is not totally intuitive, but can be learned very quickly and is effective for its purpose. You can easily navigate multiple translations, study guides, and so forth. Great selection of study guides and bibles. It is quick to navigate books of the bible so you can follow along in church.
Lastly, I love that its multi platform. I have Apple devices, Microsoft devices, and Google devices. This software is available on all of them, and has all my content and at no extra cost. Im not being forced into an ecosystem. I can this awesome app on the right device for the situation.
