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 34 languages.
