### 3/5 — Getting better!

*2014-08-25, version 6.1.0*

This version seems to have fixed the major issues of the previous update but it is still amazing that the developer has managed to bungle the interface of what is a simple online form.

### 3/5 — Not as precise as Brewers Friend App

*2014-08-18, version 6.1.0*

This app is decent and will get the job done, but its calculations are not precise and will cost you more DME  used in your starter.

For example: using the Brewers Friend App vs Mr Malty. 

Both calculated with:
-8/16/2014 age yeast
-set to 1.080 OG
-pitch in 5.25gal
-Stir Plate

Mr Malty will limit at growth rate telling you you need 1.75L starter to make the required 287 billion cells. This is a limitation and a flaw. If it showed you how many cells were being created like Brewers Friend does you would see that 1.35L starter would be almost dead on. Thats 40grams of DME you could be saving if your doing the standard 10g/100ml. 

For $1.99 its a good app, but if you want more precision and the ability be be more precise with your beer, go with the brewers friend yeast calculator. It also allows for step up calculations.

### 1/5 — Doesn't calculate properly

*2014-08-12, version 6.0.0*

Since the new update, it isn't calculating starter sizes properly. It's saying I need a 26L starter for 5 gallons of 1.054 wort.

### 2/5 — Revamped Does Not Equal Better

*2014-08-10, version 6.0.0*

The previous version was fine.  Now the yeast viability parameters are on a separate page.  Why? There’s plenty of white space on the “Calculate” page to support them AND the fermentation type.

The yeast information on the “Additional Info” should include the optimum fermentation temp.  And, at least on my copy, WLP001 is totally missing!

### 1/5 — Horrible Update - Don't buy until it's fixed.

*2014-08-09, version 6.0.0*

They took a great app and made it unusable. Need to pitch 8 vials of 1 day old yeast for a 1.055 beer???
Yeast info is nice addition, but it doesn't even include WLP001 (must be a really rare strain no one uses). How about vital stats like temp range, attenuation and flocculation??
Don't buy this until it's fixed.

### 2/5 — This update is kinda horrible...

*2014-08-09*

In terms of functionality, this update is really, really bad. The settings don't quite work right and seem to intermittently take effect on the calculations. The interface is awkward and confusing. The harvest date button seems to not work, but if you press on the actual text next to the button, it takes effect. This app is now just infested with bugs. Yuck. 

On the plus side, the additions of White Labs and Wyeast yeast strains and descriptions is really cool. They'd be even better stats if things like attenuation, optimal ferm temps, and other info was included. Also, the app also looks better, I suppose. 

For now, I'm going back to the website calculator. I'm sure these issues will be fixed, but at this moment, this app is totally useless for me. :(

### 1/5 — Used to be great...

*2014-08-09*

The interface is terribly buggy now, things have been buried where previously they were readily accessible. This, "revamp" is an unfortunate step backwards. Sadly I didn't back up so I've lost the old version and am stuck with this rather questionable version. I only hope that it'll be fixed soon. The old design was admittedly clunky and the icon peculiar to say the least but the app was imminently usable; now it's just painful to navigate.

### 3/5 — Bring the yeast type option back to the main screen

*2014-08-08, version 6.0.0*

I do not like the number of steps it takes to switch from liquid to dry. Was easier before.

### 3/5 — Real Good App, High Price$$

*2014-06-13, version 5*

The ease of use for accurate starter calculations is valuable. I'm all for supporting the time and research that went into developing this App, but as far as Apps go, this IS a Pricey one. I agree with some of the other reviews, more content would ease the pain of this purchase.

### 1/5 — Not Worth It

*2013-10-31, version 5*

Can I get a refund? This app is way too basic for $5. I understand you use it to keep the bare bones website running, but this is awful. I had no idea how useless this app would be.

### 3/5 — Handy But Needs More Value

*2013-05-11, version 5*

Works exactly like the online version but how it's worth $5 is beyond me....maybe if it had more value like say a multi stage starter mode.  I'm not pitching 6 packs of old yeast, I would always do stages in that case...

### 2/5 — Not Currently Worth the Price

*2012-12-18, version 5*

It does the same thing as the free on-line calculator, but it looks like someone's first iOS application. Not a professional job, and not worth the $5 price being charged. It needs more work.

### 4/5 — Worth it

*2012-11-11*

No, it's not the slickest interface and you can always use the free tool online, but it's still worth the cost. I prefer this calculator to others I've used like BeerAlchemy. Jamil's been a huge help to me in my brewing and he literally wrote the book on yeast. I don't mind tossing $5 his way for this very useful tool.

### 1/5 — Doesn’t work

*2021-07-27*

Can’t change starting gravity or volume.  When I enter new number it always changes back to 1.048 and 11 gallons.

### 1/5 — What a waste of money

*2020-11-30*

Really nothing to this app. Hard to use not much too it a huge waster of money

### 1/5 — Too simple

*2020-05-21, version 6.5.0*

Doesn’t allow dry yeast. Won’t allow multiple steps. Not worth the money. Disappointing.

### 1/5 — Unfortunately, no longer working

*2020-02-19*

I have had this app for years, just started brewing again, and the app no longer functions. It was a great app contributed by Jamil, when there were few alternatives to doing it by hand. 

Fortunately, there are lots of other tools now available. I would recommend Brewfather which has a broad home brew capability, including yeast starter calculations.

### 1/5 — Terrible

*2018-08-25*

What a piece of rubbish. This app tells you nothing and is a total waste of money. Do not buy!

### 1/5 — Save your money

*2017-03-04*

This app does not give the same options or calculations that the website give.

### 1/5 — Waste of $

*2016-02-02*

Don't waste your money! Free calculators do more than this worthless app.

### 1/5 — 😢

*2015-10-15*

Read the reviews, or shall I say lack their of before you even consider purchasing this application!  It seriously serves no purpose!

### 1/5 — Not Worth the $2.99.

*2015-10-09*

Save your $. There are better yeast calculator apps available that allow multiple starters to get you where you need to be, especially for big beers. Checkout Yeast Pitch. Great app and worth the price.

### 1/5 — Liters of starter needed

*2015-03-19*

Where can i find "Liters of starter need".  Thought it would be the same or better than the free calculator.

### 5/5 — Works great on iPad

*2020-12-27*

Well worth the $2.99. I’ve been using the desktop version that requires Abode Flash since it was developed. With Abode Flash being discontinued I bought this and it’s just as good as the desktop version.

### 5/5 — Works Great

*2020-08-17*

I’m not sure why everyone has low rating of this.  I find it works great, been using on my iPhone for years.  Life saver when you’re at the store and find all they have is older yeast.

### 5/5 — Easy to use and navigate

*2014-08-31*

Just like the Mr Malty website, the app have me all the tools I need to estimate my yeast count.  I found it very easy to navigate the new look and was able to get the same number from both the app and the website which makes me trust it even more.  Highly recommend.

### 5/5 — Version 6.1 is much improved

*2014-08-17, version 6.1.0*

A+ Greatly improved.

### 5/5 — Love this app

*2014-08-09*

Love this app, especially the new redesign. So far it has been accurate and consistent for me, I feel like my beer is better than it ever has been because I'm finally pitching enough! 

Thanks!

### 5/5 — Support this app

*2012-10-27*

This starter calculator is essential to taking your brewing to the next level.  Get it, and use it to ensure you are utilizing correct pitching rates (you may be surprised at how much you're under-pitching).  We need more apps like this in the App Store, so support the community by buying the app! ;)

### 5/5 — Small to price to pay...

*2012-09-20, version 5*

If you have learned anything from JZ and BN that has made you a better brewer then this app is very reasonable.  It is basic but works great and is nice to have on the iPhone.

### 5/5 — Mr

*2012-01-13, version 5*

This is the best app of its type out there. Happy to spend the money to have it on hand-literally😜

### 5/5 — Love it

*2011-12-16, version 5*

Use it every brew, thanks jz

### 5/5 — Great resource.

*2011-11-23, version 5*

Like the mentions below! I agree 100%. Great for on the go calculations at the brew shop to check viability using the dates on the packages.
