# Equa vs BiAffect3

The clearest difference is in-app purchases: BiAffect3 at none against Equa's 12. Equa's advantage is update cadence (every 10 days vs every 4 months) and ratings volume (240 vs 6). On price, rating, ads and iOS requirement there is nothing between them.

Both are free to download. Equa sells 12 in-app purchases, starting at $0.99 per month. BiAffect3 asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Equa against 5.0 for BiAffect3. That said, the two scores are not equally well evidenced: Equa has 240 ratings behind it against 6, so its average is the more settled of the two.

Equa ships an update every 10 days, BiAffect3 every 4 months. The most recent releases landed on October 14, 2026 and October 7, 2026 respectively.
