## What is Parallel?

Parallel. Calculate more.

DO MORE AT ONCE
Why calculate one thing at a time? Run 2, 3, or 4 calculations side
by side, and arrange them however you like with drag and drop. No
more memorizing one result just to punch it into the next — it's
all already on screen. That's the whole idea behind the name.

ONLY WHAT YOU NEED
No bloat, no clutter. Scientific mode covers exactly what you'd
expect from a real scientific calculator — nothing more, nothing
less. The converter covers 57 world currencies plus Bitcoin,
Ethereum, and a handful of other crypto. Simple, on purpose.

YOUR HISTORY, YOUR CALL
Parallel only saves what you choose to keep — each calculation with
your own note attached, kept separate for standard and scientific
mode. Share any result straight from history, wherever you need it.
Prefer to keep it private? Lock it all behind Face ID or your
passcode.

MADE TO FEEL RIGHT
Swipe between calculator, scientific mode, and converter. Feel every
tap with haptic feedback. Add a widget to your Home Screen, or pull
it up instantly from Quick Menu.

MAKE IT YOURS
Free with the Classic theme. Unlock 10 named themes, a set of
distinctive fonts, and the 4-screen layout with Parallel Pro — a
one-time purchase, no subscription, ever. Your calculator has never
looked this good.

No ads. No data collected. Available in 9 languages.
