I'll join the I Ching test — happy to commit to the full 14 days with real daily opens. Since you're offering to test back: I built PeerPlay, a free reciprocal-testing exchange, so if it's easier than manually tracking a swap feel free to add your app there too. Sending my Gmail via the opt-in link now either way.
