Math ain’t mathin’
Extremely inaccurate.
Calculator Is WAYYY OFF
Don’t use this calculator it is wayyyyy off.
Junk
Display is poorly laid out. Boxes are included to Calc 93 or E required to achieve proper E level. Problem is screen content bleeds into each other.
Look around for better free apps that actually work.

Version Update Issue
I updated to the newly released version and now the App will no longer run on my iPhone 7
Needs work
I can’t see though my tank and measure how many gallons are remaining in my tank. Needs to be simplified to tell me how many gallons I need to add to my tank to get desired octane.
App works great but needs a save feature
A year ago the developer said there was an update coming out to save custom settings. Still needs that update. For a paid app there should be support.
Needs save certain fields.
You said it was coming almost a year ago. Thanks.
Love the app. Just wish one thing.
Terrific app!!!
Only wish there was a "save custom settings" feature, so those of us with custom tunes can save the percentage of Ethanol we run.
Fyi. Arizona only has E54 now. I'd like to set that at default as well as my tank size and desired E%, when I mix.

Response from developer
Thanks for using the E85 app. An update is coming soon to save custom settings.
Needs settings for default button.
Great app, but should be able to save defaults for user since not all stations are 91 octane. Also, saving tank size would be nice.
Spot on
Not going to lie it took a bit to get use to but once u get it down it's a life saver for people who have a fuel percentage slot on their car/tuner. Cross checked it with some other online e85 calculators and it's pot on 👌
Pretty good but..
2/2/16 Update: has a bug that makes the app display 9% more ethanol mix than desired goal
Needs 2 things
1) to save input data in memory.
2) to fix bug where octane is affected by changing ethanol % and requires gas octane to be ready entered to reset.
Also, needs to calculate the octane based on the e85 pumps octane (via input) and not just the octane of e85(105).
Ex. it needs to compensate for the total change away from e85, if I input the station only gives out e81 at their station (most in ca do 81.5%) but don't know the octane at that pump. Then the octane should be 18.5% lower based on the concentration as well as the e10 in the gas and octane used in the gas

Decent, but one flaw
Used this a few times. It works, but absolutely hate that I have to refill information every time I load this app. It does not save previously saved info. For example, tank size or desired E% rating.
