HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (0.9 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.

Feedback

All working good

★★★★★Jun 1, 2025
Huge time saver

Use this app daily while on ship for ETA calculations, compass errors and estimating sunrise and sunset. I’ve tested the compass errors against my own calculations and come out almost exactly the same (within the margin of error you’d expect for rounding). The entire bridge team onboard now uses it and recommend it to all.

★★★★★Sep 15, 2021
Doesn’t work

Put all the info in and hit calculate then the app closes
