picocalc

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 :)

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

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).
