Solve - Graphing Calculator App Reviews

Easy to use, simple to learn more complex features with really nice tutorials. Even does time graphing which most other calculators with graphing dont do.

The good: Solve provides most of the functionality you would expect from a basic scientific/graphing calculator, with a simple UI thats pleasant to use. Its not the most powerful thing in the world, but it should be sufficient for mathematics at up to a high school-level. The bad: this calculator app uses raw floating point numbers for calculations rather than an arbitrary precision decimal library, with the result that 100 + .1 equals 100.099999999999994, among other errors. These small inaccuracies compound as you perform more and more operations, which is a problem in particular when calculating things involving dollars and cents. Using Solve involves a minor but nevertheless existent trade-off between convenience and accuracy, and whether its still worth using depends on how acceptable this is to you.

Ive tried numerous calculator apps over the years this is my favorite. Great intuitive interface - it just works. Kudos to the developers!

Very interesting idea, but awkward to use. Surly, the keyboards for each can be on one screen. Theres plenty of room. All the sliding around is distracting and pretty annoying.

I bought the Solve Pro app a while back, but now its GONE!! I paid the $2.99 for the app, but they deleted it!!! They now expect me to pay AGAIN for features I have already paid for!!! What a rip-off!!!!

This is the best.

I love this calculator. Its worth paying for the pro version if you deal with graphing and somewhat complex equations. I have one problem though... I cant find the negative sign. Other than that its great.

very useful！

After trying many different calculator apps, this is the first one that has actually replaced the default iPhone calculator for me. It is perhaps a bit more colorful than needed, but the extra colors pop out and make it a more pleasant app to use. The memory features in the app are amazing for people who do repeat calculations using the same numbers.

Totally in sink with the learner. Engineered with the users needs in mind! Creating with NO LIMITS is the vision of the future.

Great download!

This app is not only comprehensive, its also fun!

It does everything I need in a fun way thats intuitive to how I think and operate. Ill take it!

Fantabulistictastic. That is all.

Coolest interface i have seen and works perfectly. I would recommend the pro version

Great app!

Best calculator Ive ever used. Really flexible and allows you to have multiple virtual calculators. Plenty f features that would cost 10x more if found on a physical calculator ..

Definitely the best calculator app Ive found. This is exactly what Ive been looking for in a calculator app. However, I think visually, it would go a long way to remove the drop shadow from the text in both the icon and the app itself.

Must have app!

Its best calc in AppStore!
