# Kibu vs Sirkl

The clearest difference is in-app purchases: Kibu at none against Sirkl's 1. Kibu also leads on ratings volume (173 vs 13). Sirkl's advantage is update cadence (every 3 days vs weekly) and iOS requirement (16.4 vs 18.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Sirkl sells 1 in-app purchase, starting at $29.99 per year. Kibu asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Kibu against 5.0 for Sirkl. That said, the two scores are not equally well evidenced: Kibu has 173 ratings behind it against 13, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Kibu ships an update weekly, Sirkl every 3 days. Both last shipped on October 24, 2026.
