HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (28 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Price and subscription43%

10 of the 1 and 2 star reviews.

★★★★★ I've bought this app twice and now they broke the app again so I'll pay a yearly subscription of 30 bucks.
Worse after an update30%

No customer support9%

2 of the 1 and 2 star reviews.

★★★★★ ——- I did contact customer service and heir response, buy the new app at full cost, not a solution that works for me
★★★★★ Reset password multiple times and it still fails to recognize it. Called for help and of course no is available. They will call back within the next 24 hours. Isn't that lovely. If you can get to app to work its great…
WHAT THEY ASK FOR
  • They should have the decency of providing the newer version of the app for free to the customers who have paid already. 1★, Jun 1, 2018
  • I wish they give my money back. 1★, Dec 9, 2016
  • Wish they would list abx rather than having them in folders - hard to quickly find some of the more obscure abx hiding in "other pcn" etc. 5★, Aug 25, 2012
