Narrative:

In contact with the tower; about 3 miles west of the airport; instructed to call 2 mile downwind to runway 08. A little more than 3 miles out I got a collision warning on the ads-B on my ipad; 10 o'clock; 2 miles; 200 feet below. I didn't see the plane until it was a couple hundred yards away. I pulled up to increase the vertical distance and the other plane continued on course. I continued the pattern and landed normally. I didn't advise the tower of the event.
