If this were a free app that let you upgrade to multiple routines for $2 I would honestly probably like it.
But in the app world economy, chargning $2 to download an app with really quite basic functionality only to charge another $2 to "upgrade" it to allow a feature that really should be included feels pretty sleazy...
There are many feature-rich and complex apps out there for free and absolulely phenomenal ones in the $3-5 range. Paying about that for whats essentially an alarm-clock egg timer (which provides functionality that could be easily replicated in iCal) is silly.
