## What is Rhythmetic Calculator?

Rhythmetic is free. The everyday calculator you'll actually keep on your home screen — with finance depth most calculators don't have.

FREE, FOREVER
Basic and scientific modes with a formula bar you can type into. Tape history so you can see your work. Tip splitting, currency conversion, and three finance calculators — loan, interest, and salary. Curated internet radio while you work. A nine-pad soundboard.

PRO — ONE PURCHASE, NO SUBSCRIPTION
All 10 finance calculators: home affordability, VA loan and funding fee, auto, 401k, Roth IRA limits, Social Security timing, and wealth scenarios — with saved history. The full 27-pad sampler across three banks, with mic recording, echo, reverb, flanger and 5-band EQ. Add any radio station by URL. iCloud sync across your devices.

TRY IT FIRST
Start a 7-day preview of Pro. No payment, no card. When it ends, Pro features lock — but nothing is deleted. Your samples, stations, settings and history stay exactly where you left them.

BUILT FOR ACCURACY
Version 3.0 corrects VA funding fee, Roth IRA contribution limits, and Social Security retirement calculations against current federal guidance.

PRIVATE BY DEFAULT
Calculations stay on your device. Analytics are opt-in, anonymous, and off unless you turn them on.
