Nice, but needs work – picocalc free Review

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).
