Fixes: the out-of-range buzz now closes its screen by itself; the Bluetooth knock works even when Whistle is already open; the out-of-range buzz ignores short Bluetooth blips (waits 20 s); settings stay in sync with the phone page; quiet hours 23:00-07:00 selectable on both sides; journal shows the date for older events; lower battery and flash use.
Renamed to Whistle, with a new icon.
Ring your watch from your phone: the settings page is now one big button, which buzzes the watch and lights its screen even when Cairn isn't open on it. No setup needed. Everything else moved under Advanced.
First release. Siren with escalating volume, vibration, screen strobe, double-tap to stop, find-it timer, and a journal of Bluetooth connection events. Experimental Bluetooth knock and leash, both off by default.
