# Ratios vs CIDR

The clearest difference is in-app purchases: Ratios at none against CIDR's 1. Ratios also leads on ratings volume (79 vs 1) and iOS requirement (10.3 vs 15.6). CIDR's advantage is update cadence (every 3 weeks vs every 5 months) and rating (5.0 vs 4.7). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. CIDR sells 1 one-off in-app purchase. Ratios asks for nothing beyond the download.

CIDR holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Ratios has 79 ratings behind it against 1, so its average is the more settled of the two.

Ratios ships an update every 5 months, CIDR every 3 weeks. The most recent releases landed on August 15, 2026 and June 30, 2026 respectively.
