frequently when you open the Twinkly app, it displays "recalibrating effects'. This message stays on the screen for minutes.
My experience is people get board waiting. And they never get to try twinkly, because they loose interest before 'recalibrating' completes. It's also tedious when you come home or leave, and you have to wait to turn the lights on or off.
If re calibrating is doing the exact same thing every time you open the app; maybe it can cache the calibration. And only recalibratie when there is a change.
