The best To Do service/app - by a mile!!! – Nirvana for GTD Review

GTD or not, there is no better To Do service in the market. They took a good while to produce a solid iOS app, but now the full service is fantastic. I've tried most GTD and To Do services, and none can beat Nirvana. Keep up the great work!!!
