There are many calculators apps for iPhones and considering we have been using the calculators on our phones long before we had iPhones (in fact we often used them on our digital watches), they are a function that most of us really want to see on out iPhone or iPad. There are now some pretty impressive ones out there, many of which go one step further than even a scientific calculator with the ability to graph results of equations. These can be really useful to students as well as anyone who works in the mathematics field or has a job or hobby that needs them to make graphs and so below are reviews of some of them.

There are some subtle differences between the apps. It is a good idea to take a look at all of the available options and decide which has the functions that you need. You will want to think about what you want to use the app for. It is always tempting to go for the free option, but it is worth taking a look at them all as you may find that you take a long time to learn how to use an app and then find it does not do exactly what you need. This may mean that you will then have to buy one and learn how to use that. This could waste valuable time. Therefore make sure that you read all the reviews that you can find and make sure that you have enough information to make an informed decision as to which one will suit you and your needs the best. It may seem like a lot of work, but you could find that it will take even more work if you have to learn a selection of packages because you have not done enough research initially.
