### 4/5 — Seems to have gone buggy with iOS 8.

*2015-01-16*

Such a shame. I have use this app daily for over five years, and have found no substitute. Sure, there are all sorts of checkbook and let your balancing apps out there, but none that allow me to get in, adjust my balance, and get out all in the seconds as I leave the cash register. Well I have virtually no features, it won the speed war. 

But now, with ios 8 it no longer seems to do it's math correctly.

### 4/5 — 落ちる？

*2011-08-02*

設定、加算、減算 どれを押しても落ちます(;･∀･) でもバッジには正しい数字が反映されてるので そうゆう物なのかしら？そこが謎なだけで、便利に使わせて頂いています♪ 私も このアプリ２つ欲しいです！  インフォメーションに書かれてる有償バージョンも期待しています☆

### 4/5 — Works perfect

*2010-06-09*

Works great to track my monthly gas allowance from my job. I just enter the allottment on the 1st and subtract the amount each time I fill up. Would be better if you could track more than one category and decide which one is on your desktop though.

### 4/5 — リセット？

*2009-01-14*

設定押すと、前の値はリセットされるようです。
できれば、同じソフトを2つ作り、ホーム画面に2つ並べた得点板の代わりになったりしますね。
どうせなら得点板のソフトがあればいいですが。

### 4/5 — Great for keeping track of numbered projects

*2008-08-11*

I work in video production and this app is great for keeping track of duplication. For instance, if I have 75 DVD's to run off and my duplicator can only run 8 at a time, it can be a pain to keep track of how many I have left to run (especially if I encounter a bad disk) but this app makes it simple. The only thing I wish it had is the ability to track multiple projects.

### 4/5 — Interessant

*2008-08-04*

Das Programm ist eigentlich ganz Interessant. Man kann eine beliebige Zahl eingeben, die dann als kleine Nummer über dem Symbol angezeigt wird. Von der Zahl kann man dann Werte abziehen oder dazu rechnen.

### 5/5 — So simple yet so useful

*2008-07-29*

Using it as a calorie counter. It's simple and so useful.

### 5/5 — In

*2008-07-20*

It's not a calculator... It keeps track of numbers quite well

### 4/5 — Simple, straighforward

*2008-07-16*

Don't expect it to do as much as the calculator. It's great for keeping score (better than scribbling on paper) for games, tallying expenses, counting random assorted things, and the running total is displayed on the icon itself.

### 5/5 — Decent

*2008-07-15*

I actually really like this program. For keeping track of your current expenses on a business trip or just your personal finances, this app makes it very easy.  Couple taps to record an expense and you're done.

### 5/5 — Great for tracking bank balance

*2008-07-13*

This app is great for keeping track of your current balance & you can subtract your purchases with just a few quick taps. The current balance even shows up on the Home screen! No
more overdraft fees!

### 1/5 — very easy and simple

*2008-12-28*

I like this app simply because, it is easy to use, and it does not take any time to learn where the buttons are. although other may find that it is a waste of time, it is perfect for keeping a running total, which is what I think its purpose is.

### 1/5 — Bof Bof

*2008-10-30*

mouai je vois pas trop l'utilité ...

### 1/5 — Don't Bother

*2008-08-02*

I downloaded this program, and it works as advertised, but I deleted it.  The native calculator with my ipod touch is much better and quite accessible.  And now that math functions have been added to the native calculator and it can be used in landscape mode, there is really no reason for this program to take up valuable memory.  Since Apple has upgraded the calcuator in software version 2.0, those developers wanting to submit a calculator program to the App Store really need to offer something unique.  My suggestion is to leave this program in the App Store.

### 1/5 — What am I missing?

*2008-07-13, version 0*

A clear example of everything that is free is not being good for you.

### 2/5 — Broken

*2024-02-20*

This little app used to be brilliant, now it is broken and I can’t seem to find any instructions about the problem, or how to fix it. There’s now a message appears on the home screen, saying ‘Please grant permission to display badge’. I have gone into settings and made sure the permissions are correct to display a badge, but still the message remains. Also, pressing the + or - key does nothing. Is there a fix for this?

### 2/5 — What what in the but

*2009-07-20*

Total sinnfreies prog. Zwar ganz lustig anzuschauen aber nicht wirklich sinnvoll.

### 3/5 — ゲーム中のスコア確認に便利♪

*2008-08-11*

・マイナス値だとホーム上で表示されないのが残念です。
・設定ボタンがあるのですが、押すと終了してしまいます。(・_・？)

### 3/5 — Nice, but needs work

*2008-07-31*

This is a clever idea, but the name is confusing. It should called number tracker or something like that. 

Basically, it is used as a tracker. For example, say you only wanted to consume 1600 calories per day. You might start with 1600, then every time you ate something, you could just subtract the number of calories. This way the program tracks how many calories you have remaining. The program icon on your home screen lists the current number (calories remaining in this case). You could do the same thing with your monthly entertainment budget or any other number you wanted to track.

There are some problems. The main issue is that every change boots you out of the program. If you have just one change, that's great. Otherwise, you need to reopen the program for every change. This alone is enough for me not to use it. 

Another  problem is that it cannot display 0's or negative numbers. The developers say this is an Apple limitation, but I wonder if there's a way around it (for example, changing the numbers to numerals (characters), then displaying them, or otherwise displaying negative numbers with a red background and positive numbers with a green background).

### 3/5 — Could be Useful

*2008-07-15*

This is a simple Calculator that makes the current answer to a sum visible on it's own home page icon. (view the second sample image)

It could be used for many things, like keeping track of the money you are spending on a shopping trip, for stocktake or for scoring. 

Minor niggle, which the author blames on the iPhone, is that it cannot display a negative number on the icon.

Despite the appearance of the screenshots it runs in English too. I am not sure if the previous reviewer has even tried it?

I would like to see it modified so that I could use it to keep track of my three kids pocket money.
That would require 3 instances of the App currently.

### 3/5 — Helpful

*2008-07-13*

I find the way it keeps the number set helpful. And only having 3 function buttons is nice, too, since all I'm using it for is to add and subtract. I was looking for an app that I can keep track of income & expenses, one at a time, by just giving each item a name, value, and whether its a purchase or sale, that will keep a running tab, but this is the closest thing I've found so far

### 5/5 — A Classic

*2024-02-11*

So happy to see that this app is here! Picocalc is of the first apps I ever downloaded—way back on the 1st gen iPod Touch running system software 2. Right now things feel unexplored and exciting like 2008 again!

### 5/5 — Simple, No Other Counter App with Badge Out There

*2018-10-01*

Been using this app for 10 years. I may change phones but I always keep this app on my first or second screen. It’s simple: just set a number and then use the calculator to add or subtract from that starting number, and the result posts as a little red badge in the home screen app icon.

I tend to use this as a quick budget calculator. I set it to my monthly budget for food and expenses, and it gives me a quick-glance preview of the number by just looking at the badge. I can quickly see how much of my budget I have left to spend on without even opening the app.

One thing I wish this was capable of is sharing with another user, real-time. If my partner installed picocalc and it could update every time I added or subtracted, then we could both keep an eye on the same number separately. Likewise, it would be useful if the other person could subtract a number when they spend on lunch, and my picocalc showed an updated number.

I’ve tried finding any other app that does something similar, but this is the only app that seems to exist of its type. Kudos to the developer! I hope you keep updating and maybe even scale it up just a little bit more :)

### 5/5 — Rules, owns, etc

*2015-05-25*

I was waiting for an update to make it compatible and now that it's here, blows my mind. It's crazy how lost you are when you lose such a simple app, but thank Buddha we got you back.

### 5/5 — いいです

*2013-03-28*

かなり面白いアプリケーションです。
SS撮影時のカモフラージュに使わせていただいてます。

勘違いされてる方がいるようですが、設定は指定した数値をそのまま"設定"するということです。
また、落ちるのは仕様だと思われます。

### 5/5 — Love it!

*2011-03-09, version 0*

Use it every day. Very fast. Nuff said.

### 5/5 — いい。

*2010-05-12*

一週間分の立て替え金額をぱぱっとメモっておくのがかなり楽になりました。
同じアプリが複数欲しいです。
１つは立て替え用に。
もう１つは外出時に使った金額の即メモ（あとで違うアプリで家計簿をつけるため）
色を変えただけでもいいので…とかできないのかなぁ。。

### 5/5 — Not much, but great app.

*2009-02-02*

I know that this app doesn't really do much, but I have found it very useful as a quick budgiting tool. It's easy to put in how much spending money you have to spend and then just subtract it when you do. So you will always know how much money you have to spend!

### 5/5 — Also..

*2008-09-27*

This app makes a really great countdown.

### 5/5 — Ok macuda?....

*2008-08-19*

First of all your I'm guessing using an iPhone or iTouch, therefore your using the same device as these kids... So obviously if there iPod is "junk" so is yours... And if you don't know that apps do sometimes crash the device your a complete idiot. And after saying and apple product is "junk" do you really think they are going to listen to a request from you? It's idiots like you who shouldn't be able to write reviews. 


Also the app makes complete sense and does what it shoul, it's just a simple way to remember a numder. Good job

### 5/5 — Cool app.

*2008-08-03*

I've been using this to keep track of my bank account. My only complait would be that it can't display tenths or hundreths for tracking change.
