I've had an app that kind of blew up and grew to thousands of users in several weeks and then reach top 200 Lifestyle Apps on Appstore. It also had more than 100 ratings with an avg rating of 4.6. However I stopped updating a long time ago and removed it from Appstore, I noticed basically that old ratings get erased after version updates to the app which I guess make sense as it ensures reviews are actually of the current version of the app so.I guess Snaplight just died in popularity after several updates.
