Doesn’t support metric
Where I live all pumps are in metric. So telling me ounces per gallons is useless to me. I might as well do the calculation myself. Also doesn’t like to do fractions of units when entering your amounts. If I don’t buy a full unit it won’t let you calculate. App is a bit garbage.
Terrible
Just keep it simple, why does it matter what the local price of gasoline. Get rid of that. Keeps saying please select gasoline treat. App needs to be updated. Doesn’t work April 2026
Not working
The Select Octane is not responding
Stopped working
The calculator just stopped working and won’t do any calculations. Keeps asking me to select gallons treated when I entered it already. And it’ll freeze if I try to click out of the input box.
Great for quick ratio calculation
Can come up with my ratio on the fly. Works well. Gets me what I need.
Simply doesn’t work
The app that is meant to simply calculate the amounts is asking to login to proceed. It’s just ridiculous and now it’s simply not even login in. Server error.
The App No Longer Works
I have used the Boostane app successfully for well over a year. Today, it tells me that “no server by that name exists”. In reading other’s reviews, it seems like a common issue. So now, the app is non-functional. Also, now it wants my full name and email just to use the calculator. They already have it, since I buy my Boostane directly from the company. But, in today’s world, who wants to give out personal information to use a simple calculator?

Needs more octane settings
Would be nice to have more octane settings on the calculator. It only goes to 91 for a starting octane, would be nice if it went down to 87
App is broken
Unable to click to adjust certain parameters. Unusable app.
Very bad functionality. Simpley doesn't work.
Once you input volume, starting octane, target octane, it stops working. Youy can't 'back-up', you have to shut it down and re-start. Secondly, it requres a lot of info, info to get ripped off. Lastly, Boostane offers a 10% discount for going thru all this crap, then no discount, no coupon, nothing....If This is how they run their company and make apps, I do NOT want there product in my automobile or toys!

Irritated
They actually convinced me not to use their product by asking for my name and email to use their app. Why does either of those things need to be required just to open the app? I’ll use another product
Sad! They are missing an opportunity.
Should be a simple tool with basic math that could be helpful to users. When it does work things like “1.56 of a bottle” is very poorly thought out. What is 1.56? Also, what is a bottle? Pretty sure they sell several size bottles. That’s just one example. Other reviewers can cover the rest of the opportunities for improvement.

App is not working at all!
Attempted to access the calculator to see if it would be worth using this as an additive. No dice! The app doesn’t recognize my email format of @yahoo.com

Improved.
I calculate for octane number using 91 octane and I get a 95 octane from 250ml (about .25 ounces). Notice a decent improvement in acceleration

App doesn’t work
App has been working fine for me the last 15 months and now it just says it can’t connect to the specified host server name which is USA. I need this to calculate my octane levels for testing. Please fix this asap
Can’t get app to work
Can’t get this app to work. Keep telling me to “select gasoline treat” but won’t let me select things.
It could be so simple but it’s not
This app is designed by an engineer using common core math.
Many bugs, sucks can’t use it
Too many bugs to list. Crap.
Error 3
Keeps getting error 3 message. Entering valid email and everything. Dont understand why you guys need an email and FULL name to calculate octane levels. Great product though, it works. Please fix this app so we can continue to enjoy this product and mixing charts so our cars dont blow up.
ERROR 3
Don’t download. Can’t even get into app.
Deleting, fix your ****
