The app is indeed only available for tablet this is simply because there is no layout made for smartphones, it would need a complete redesign of the layout. There are a lot of buttons that need to be displayed at the same time which takes a lot of screen space.
In another thread on their forum (my google-fu is weak atm) they mention it's limited to 600dp - effectively 7inches or above (fnar fnar :p).
I did run it on an LG G2 mini (540x960) but it only showed half the buttons as the sizes and placements are hard-coded
Export is only on the Windows App ... Menu -> File -> Export (Ctrl-X)
It places the csv output into %LOCALAPPDATA%\VirtualStore\Program Files (x86)\Velleman\WFS210
It also puts a JSON file there with details of the capture - ie Timebase, V/div, Coupling, etc.
It places 4096 values into the csv - it doesn't stream them in continuously - same 4096 samples with WiFi or USB.
I haven't had the windows export fail on me - If you start the app with "Run As Administrator" does the export still crash?
I agree the tablet version isn't worth much for logging since it uses an Access Point so you are pretty much limited to logging to internal storage.
I wish Velleman would release the Windows Code
... and firmware!
I hope Velleman submit an update to the Play Store sooner rather than later.
Edit: Now I've got some vaguely working tablet software I'm actually quite liking the unit for the £20 though if I'd paid £100 for this I'd have sent it back and sworn to never buy Velleman again :p
