# Calculo vs Pixel QR

The clearest difference is ads: Calculo at none against Pixel QR's shown. Pixel QR's advantage is update cadence (every 2 days vs every 6 weeks) and iOS requirement (16.4 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Calculo sells 3 in-app purchases, starting at $4.99 per month and Pixel QR sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Calculo ships an update every 6 weeks, Pixel QR every 2 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
