Given the security risk with being able to unlock iPhone with default calcualtor, deleted, and researched for a reliable calculator. Best phone calcualtor ever- used it to help spouse through college math course…. Better functionality than a scientific calculator… perfect
Worth the cost, especially if you want every possible range of calculators. Scientific, graphing, etc.
Love the range of operations and capabilities (like memory). I have the paid version.
'Nuff said. It's the best. Get it. Period. Five year later, still best. Get it. Now. Ten years later; still the best and getting better.
The best calculator in the world
This is unusable on macOS because not doesn’t accept keyboard inputs
A very capable calculator. Takes time to learn how to use all the features.
