I have never been a big believer in focussed and productive presentation design on tablets, but presenting documents (mostly in 1-on-1 meetings) and making last minutes edits are important on mobile devices.
We are not making tablets a design priority, but have deployed some changes to the code that makes SlideMagic run pretty smoothly on an iPad (iPhone is still not optimal). Try it out and report back any bugs. Android tablet users, let me know what happens (I have not tried things out there yet).
With the large iPad Pro coming out later this year, there could be a brighter future for SlideMagic on iPad given the very simple menu structure we use.
