I use Evernote for GTD. Evernote has only a limited concept of time, so scheduling actions for a future date less than ideal. There is no auto reminder system--not essential for GTD but a definite bonus electronic devices can give us.
For time based and recurring events with reminders, an additional program/service would be best employed. I use email as my reminder system with the delayed/recurring email service followupthen.
Evernote will drive you crazy with its bugs and totally unexpected roadblocks which you discover after spending hours setting something up, but at least it got one thing right right: syncing across multiple devices, extremely important for GTD. I would advise to become a paid subscriber as offline notebooks on mobile devices is essential to eliminate painful waits for notes to be downloaded from the net.
