The Wakemate team seems dedicated and smart, but as an outside observer watching the it all unfold, their communications skills are sorely lacking. Hopefully a great product will overcome in the end.
edit: On second thought, they have got to be just crazy. How is it possibly the right idea to have three unfinished mobile apps than one that works?
This was done out of a shop in the US, not sure what it is like doing production runs overseas, but I can't imagine it's much slower.
This of course ignores the time spent designing/redesigning units, however, ordering batches of something from a manufacturer doesn't take long.
Why do you think they should not of worked on all 3 platforms at once? For the sake of a minimum viable product?
I would think you would want to do one mobile app just right, and then port it to other platforms. You might do a spec for all three up front so you think through each platform, but why not push one platform, iterate, and then take what you've learned before building?
