# Contacts Cleaner vs QR Code Studio

The clearest difference is update cadence: QR Code Studio at every 4 days against Contacts Cleaner's every 3 weeks. QR Code Studio also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Contacts Cleaner sells 1 one-off in-app purchase and QR Code Studio sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Contacts Cleaner ships an update every 3 weeks, QR Code Studio every 4 days. The most recent releases landed on October 1, 2026 and September 8, 2026 respectively.
