On Device Processing

This one has two parts:

1) [DONE!] Live Court Validation (available on iOS now) — useful for properly recording games through the app.

2) Full local processing on your phone. This means if you are willing to keep the phone open for a while we can process videos on devices instead of on our beefy cloud servers. This might be a little inconvenient for processing times but we could then roll out alternative plan options for lower-cost use of PB Vision!
