HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (0.2 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.

Best rank Sep 27, 2026: not ranked. Now: not ranked. Days at zero are days outside every grossing chart. Small app: scaled like the revenue estimate above, so the line shows the trend on the same scale.

★★★★★Sep 1, 2025

Works very well. 😃 I wish the app supported dark mode, but that's a cosmetic preference so not a big deal.

★★★★★Aug 10, 2021

Simple to use and understand even for a complete novice. Does everything you need it too. Excellent app!

★★★★★Aug 17, 2020

Excellent app for a gas blender. Highly recommended.

★★★★★Jul 29, 2020

Gives no way to do a "mix+mix" blend.... since the use of pure O² is not widely used because of the inherent dangers it would make sense to offer a "mix+mix" option. P.S. I would really appreciate a refund.

★★★★★Nov 6, 2019

As a gas blender at my club, this app makes you look professional while achieving top results in required mixes

What's new in 2.0.38

- The CCR table can now also show the diluent as open circuit: PPO2 and gas density of the unchanged diluent, i.e. the bailout case - Limiting depths are listed separately for loop and diluent - Depth steps are only coarsened where the finer step adds nothing
