[autoreverse]

My weekend project from 2009 does this: http://www.crondroid.com/

One free daily cron, others paid on request (please use the contact form).

500 subscriber crons per day. We use it for in-house and client projects so have an interest in reliability ;-)

Accounts/dashboard/self-service will be added if/when needed (currently email does the trick).

All comments appreciated.
