Type a number. Read the answer. That is the entire app. Conversion has been on the App Store since 2012. Version 4 is a complete rebuild — modern, quick, and still refreshingly free of clutter. BOTH UNITS, ALWAYS IN VIEW The two units face each other in the middle of the screen, right where you left them last time. Flick either one to change it, or tap an amount to turn the conversion around. Nothing to drill into. TWELVE CATEGORIES, 96 UNITS Length · Area · Volume · Weight · Temperature · Speed · Pressure · Power · Energy · Time · Computing — and Currency, with more than 160 world currencies. LIVE EXCHANGE RATES Rates refresh on their own and are stored on your device, so conversions still work on a plane or underground. When a rate is out of date the app says so, rather than quietly handing you an old number. YOUR LANGUAGE, YOUR NUMBERS 33 languages. Unit names, decimal separators and numbering systems all follow your region — so a comma lands where a comma belongs, and Arabic and Devanagari numerals are drawn properly. BUILT FOR iOS 26 Liquid Glass, a color for every category, fluid animation, haptics, and Dark Mode throughout. ACCESSIBLE FROM THE START Every control is labeled for VoiceOver. Text scales to the largest accessibility sizes. Reduce Motion is respected. A hardware keyboard drives the whole app. NOTHING COLLECTED No account, no ads, no analytics, no tracking. The app makes one kind of network request — for published exchange rates — and it carries nothing about you. Pay once. No subscription.

MessagEase is an alternative, non-QWERTY keyboard for your iPhone and iPad. Created based on years of scientific research in user interface, MessagEase is designed and optimized for use on a touchscreen device. MessagEase is a patented, innovative design different from the antiquated QWERTY keyboard. If you believe that every keyboard must be QWERTY-like, then MessagEase is not what you are looking for. But if you are open to new ideas and up for experiencing a completely new way of writing you will be pleasantly surprised at how well, how precisely, and how fast you can enter text with MessagEase. Our current champion’s speed is 87 WPM— that's 87 Words Per Minute! Most people don't type nearly that fast with ten fingers! MessagEase essentially has 9 large keys with an optimized letter assignment to maximize your speed, increase your accuracy, and ease your writing. Since MessagEase is very different, you must spend a few minutes to get used to it. We have included several learning games to help you learn the new, innovative pattern of MessagEase—and you’ll save hours by texting and writing faster. With MessagEase you enter letters and characters with either a tap, or a drag (slide): taps for the most common characters and directional drag for the rest. Please watch the video, or see the section Essential MessagEase, to learn more. MessagEase's design is based on sound user-interface principles such as the Fitts' Law; it uses letter frequency and di-gram data to optimally place the characters on a keyboard with fewer, larger keys. That’s why the letter positions are non-QWERTY! If you are interested to learn more about the scientific details behind the design of MessagEase, please see this paper: http://www.exideas.com/ME/ICMI2003Paper.pdf We have lots of videos to help you become familiar with MessagEase quickly. Watch: http://www.youtube.com/watch?v=k3D3f3GWTSg There are many more on our YouTube channel. http://www.youtube.com/user/messagease Please also note that you can change the keyboard size by dragging up or down on the Globe Button. You can also reshape and recolor the keyboard in various ways. See Settings for details.
