Players on both sides struggled in driving wind and rain at the Omagh venue but it didn't halt a spirited Tyrone comeback in the closing minutes.
A Terence O'Brien goal put Derry in control and four points up with eight minutes to go.
The Tyrone comeback was helped as the Oak Leaf county dropped to fourteen men when Niall Holly was sent off for a second yellow.
With seconds to go, a Darren McCurry free tied up the game to share the spoils.
Tyrone go onto 3 points just one off the leaders Cork who play Donegal on Sunday while Derry despite picking up their first point of the season stay bottom.
