### 4/5 — Not a good app or developer!

*2023-07-13*

I downloaded this hoping it would be what I needed but it was far from it. There are only pre-set mixes available and I needed a 67:1. There’s no availability to enter custom mixes. Also, after I had paid and downloaded it I got an error message saying it hadn’t been updated to work with the latest OS so I waisted $1. It’s not much admittedly but if a developer is going to offer something for sale they ought to keep it updated.

### 4/5 — Great app but slight flaw

*2014-04-11*

There are 4 of these apps out there at the moment and this has by far the best UX of them all. It looks like an actual designer has worked on it, or at least someone who has paid attention to the iPhone iOS7 style guide. Problem is though, it seems like the ‘fuel’ and ‘oil’ is the wrong way around. Surely it should be more fuel to oil, so a 33:1 ratio (which is what my enduro uses) is not 33:1 oil:fuel, but 33:1 fuel:oil … or is there something I’m not seeing?

### 1/5 — Not good

*2012-01-08*

The metric version is not correct

### 5/5 — Gas app

Great app, takes the guess work out of mixing.  Easy to use.  Thanks!

### 4/5 — Gas mix

*2011-09-15*

Just what the doctor ordered but would be nicer if it had 20/1 also.

### 5/5 — Solid gold! Totally worth it!

*2011-08-03, version 1.0*
