I need this to calculate my octane levels for testing. Please fix this asap ### 1/5 — Can’t get app to work *2021-05-03, version 1.4* Can’t get this app to work. Keep telling me to “select gasoline treat” but won’t let me select things. ### 1/5 — It could be so simple but it’s not *2020-11-18, version 1.4* This app is designed by an engineer using common core math. ### 1/5 — Many bugs, sucks can’t use it *2020-01-29, version 1.3* Too many bugs to list. Crap. ### 1/5 — Error 3 *2020-01-23, version 1.3* 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. ### 1/5 — ERROR 3 *2020-01-17, version 1.3* Don’t download. Can’t even get into app. Deleting, fix your **** ### 1/5 — Error *2020-01-08, version 1.3* It keeps saying error 3 ### 1/5 — Doesn’t work *2020-01-08, version 1.3* Error 3 ???? Please fix ### 1/5 — One star because it launches on iOS13 *2020-01-07, version 1.3* App requires a full name and email address, which is already problematic, but then errors out when clicking submit. You folks need to pay more attention to this, figure out your developer situation. ### 1/5 — Cannot use *2019-12-08, version 1.3* I get error 3 when I enter my name and email ### 1/5 — error *2019-12-07, version 1.3* dowloaded the app and get error 3 code asks for name, email and country easy but not so and gives error time to delete. ### 1/5 — Useless app *2019-06-25, version 1.3* Thought this was cool when I saw it downloaded it and it simply doesn’t work to calculate anything ### 1/5 — Wast of time! *2019-05-07, version 1.3* Calculate result in ounces! Not decimal points! Oh and don’t push selling the product, we already purchase it which is why we are using the app! Epic fail! ### 1/5 — What were you thinking! *2018-09-21, version 1.3* Previous version while it wasn’t perfect, it was a lot better and helpful. People looking at this calculator are current and potentially ongoing customers. No need to push the sales, I already bought a 5 gallon pale. You sell it by gallons and ounces, give me the answer in ounces, not decimal numbers. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t support metric *2026-06-11, version 1.4* 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. ### 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. ### 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. ### 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! ### 1/5 — Irritated *2023-02-15, version 1.4* 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 ### 1/5 — Sad! They are missing an opportunity. *2022-07-18, version 1.4* 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. ### 1/5 — App is not working at all! *2021-10-12, version 1.4* 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 ## Most praised reviews (5 highest-rated) ### 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. ### 5/5 — New user *2021-10-11, version 1.4* 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 ### 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 ### 3/5 — Does not calculate ounces *2016-11-01, version 1.2* I just downloaded this app and did a calculation with it; I'm disappointed that it shows the ounces as "0" regardless of how many quarts is listed. Also, this may be a novice question, but am I correct in assuming the HP is not wheel but crank? --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
