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. ### 1/5 — Terrible *2026-04-26, version 1.4* 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 ### 1/5 — Not working *2026-02-10, version 1.4* The Select Octane is not responding ### 1/5 — Stopped working *2024-06-04, version 1.4* 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. ### 5/5 — Great for quick ratio calculation *2023-08-01* Can come up with my ratio on the fly. Works well. Gets me what I need. ### 1/5 — Simply doesn’t work *2023-07-02, version 1.4* 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. ### 3/5 — The App No Longer Works *2023-06-30, version 1.4* 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? ### 3/5 — Needs more octane settings *2023-05-25, version 1.4* 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 ### 1/5 — App is broken *2023-03-22, version 1.4* Unable to click to adjust certain parameters. Unusable app. ### 1/5 — Very bad functionality. Simpley doesn't work. *2023-02-20, version 1.4* 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! ## Frequently asked questions about Boostane ### What does the Boostane app do?
