What's New in Version 3.6.5
Fixed a problem with the alternative icon being reset if the app is quit. Sorry!
Added an option to change the app icon on iOS 10.3 or later (if the icon doesn't change on the home screen, restart your device and that will fix it - iOS bug, sorry!).
Along with the ability to change the icon between the existing blue and orange versions, there are nineteen more icons to choose from including lots of colors and some old designs going way back to 1992. To unlock those icons, we've added an optional tip jar.
Since we've never charged for an update, this is an experiment to see if people feel like dropping some extra coins into the jar as a way of supporting the release of new versions. Even if you don't tip, you'll always have the full functionality available.
Added a new "Hot Pink" tint color for the "Samurai", "Samurai Night", and "Backlight" themes.
Now blink the display if you press Equals and the answer is the same as the previous number shown.
Now the change sign button doesn't finish entering a hex, octal, or binary number, so you can keep editing it.
Now supports pasting of Arabic-Indic numerals.
The "TC" button now correctly deactivates 2nd functions.
Fixed a crash when tapping "Reset to Defaults" in settings.
Fixed a crash if you toggled the RPN setting after tapping "Done" in the Advanced section of the settings.
I've been using this calculator for years. It's fantastic. The ability to:
-Calculate in hex, decimal and binary
-Translate between decimal, hex and binary
-Perform common logic operations
-Scroll through history
-Rewind calculation steps
-Save custom functions/formulas (I've created functions like calculating solar masses of a distant star given distance and luminosity)
-Save custom constants
-Modify button size and layout
Are just the beginning of how multifaceted this app really is. I would not recommend any other calculator app beside this.
The lite version can be fully upgraded through inapp purchase. And I kind of prefer the orange icon over the blue ;)
EDIT: The new icon pack that can be unlocked by tipping James is a good idea! I get fun new icons (no functionality added, just cosmetics) and he gets more monetary support for his work! This is extra to the function packs you can purchase in the app.
I don't use it often, but when I do, it's great
I don't have a huge need for a calculator over the built in iPhone one, but I like the design of this lite version over Apple's, and it has constants and other useful features on the portrait screen without needing to rotate.
These features were not enough to convince me to pay for a full featured app, but the tip jar addition is nice because I can now give the developer a little money whenever the app helps me out, or when I feel like it. Apps don't grow on trees, so people should be expected to pay for software they use and I am ok with this approach.
Best calc app
There's simply no better iOS calculator out there. It's just plain all 'round good.
Fifth star restored after a hasty fix to custom app icon bug. Now works properly. Kudos!
