Soulver is a revolutionary calculator replacement app. Its powerful UI lets you do calculations over multiple lines, and use words alongside numbers, so that they make sense.

Soulver is great for back-of-the-envelope calculations, currency conversions while travelling, working out percentages, calculations involving changing variables, and much more.

Soulver supports Dropbox & iCloud syncing, and is also available for macOS.

WHY IS SOULVER BETTER THAN A STANDARD CALCULATOR?

- Instant answers as you type (no need to use equals!).

- Spread your calculations over multiple lines (so your brain doesn't explode).

- Reference previous answers in your current line (kind of like a mini-spreadsheet).

- Annotate numbers with inline labels (you'll thank yourself later when you read them back!).

- Do percentage calculations using natural phrases "15% off $350" (has support for 9 different percentage phrases).

- Supports over 150 currencies (including Bitcoin), and has a specially designed currency keyboard for quick conversions.

- Custom variables across all your documents, and a special keyboard for quick access to them.

- All standard math and programming functions, also available on specially designed keyboards.
