Mr Malty Yeast Calculator

Samsung galaxy S4: does not work. Does not update the yeast quantity when you insert your data. Useless, therefore worthless. You could call this theft.

The UI is outside the screen, the app is impossible to use

Could do with better instru6

The program is good. I would give it a five if I could change the volume unit of measure. I think it means gallons, but would be nice to change to litres.

Just use Google to help.

Can you devs please fix the app? Seems like it doesn't work for most people.

A little expensive though. But I've used the free web based version for years, so why not pay a little?

Have absolutely no issues with the app so far

Maybe you have to read the Yeast book to understand this app. Very unintuitive and i didnt even know what reault or information i was supposed to be getting. Not worth paying for.

Keyboard won't leave screen on galaxy s5. Very annoying. Could also benefit from some help or explanation for noobs.

Works as described. Much more convent than the web version.

Well, then you need to calculate the correct amount of yeast cells for your brew. And this calculator does it brilliantly! Been using the app and the online calculator for years. Can't live without it ;-)

This app does not work with samsung galaxy s3. It states everytime that 0 billion yeast cells are needed for the specific gravity. I tried to contact the developer to inform about this and to get a refund, but that didnt work either so no, I'm not at all happy about the app.

The beauty of this app is in its simplicity--it is easy to use, easy to understand, and an essential tool for any homebrewer!

This is a great app and find it extremely helpful and easy to use when making a yeast starter. I always find myself looking up how much DME to add to the starter. I know there is a simple rule: 1 gram DME to every 10 ml of water, but it would be nice to have this calculation included in the app.

I use Mr malty all the time. I purchased the app and have been disappointed, there have been no updates. My phone is the Samsung s4 and the text is too small. Please update!!

When I enter the info on the website for a particular beer, I get 1017 billion cells, on the app, the same inputs give me 288. The website is accurate, close to beersmith numbers. App is WAY off.

More features than any other calc, tried and true.

Wondering how viable that yeast is? How big of a starter is required so you know how much DME to buy? This is the app you need to ferment at the next level.

Does exactly what it says on the tin. Invaluable tool for brewers. I've already got my $5 value by reusing a single Wyeast pack. Only improvement would be some in-app explanation around the variables (E.g. how do I work out my non yeast content? or is 15% good enough?)

Mr. Malty's got it going on.

To repeat others: does not work with samsung galaxy s3 or s4. It states everytime that 0 billion yeast cells are needed for the specific gravity. Tried to contact the developer to inform about this and to get a refund, but that didnt work either so no, I'm not at all happy about the app. Waste of time and money.

The standard for yeast pitching calculations

For as much as i have used Jamil 's website, the least i could do is support him. The app is great, miniature version of the web site. I love it!

The OG that is loaded contains a comma that is causing the app to not give any answers. Please update the defaults, or make the system show errors.

Must have for better beer...

Great tool.

This is a great tool to have while scratching your head at the homebrew shop. Thanks JZ!
