We have no specific recommendations and Mosaic Control is extensively tested on a wide variety of iOS and Android devices. The software will adapt properly to a range of display sizes (including the extremely small screen of the iPhone 5S) and fully supports dynamic type sizing on all devices. Pick the device you’re most comfortable with.
If you are considering the purchase of an Android tablet then we highly recommend that you purchase one where the short side of the display is at least 1600 pixels of native resolution. This will provide the best balance of screen scaling options and still allow Mosaic Control to run in landscape mode.
