The old version of Fade In Mobile (and Fade In Mobile Free) for iOS and Android has been retired. Functionality, underlying technical changes, and compatibility issues with third-party cloud storage made it untenable for continued development and support.
If you purchased the older version of Fade In Mobile previously, you should still be able to download it from the respective app store. It is, however, no longer available to new purchasers.
It is recommended that users look at a new mobile workflow using Fade In Access, which provides improved functionality, collaboration, stability, and device compatibility.
