# PiKuBo vs Bright Math

The clearest difference is update cadence: Bright Math at every 4 days against PiKuBo's every 5 weeks. PiKuBo's advantage is ratings volume (95 vs 2) and iOS requirement (15.0 vs 18.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. PiKuBo sells 13 one-off in-app purchases and Bright Math sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for PiKuBo against 4.5 for Bright Math. That said, the two scores are not equally well evidenced: PiKuBo has 95 ratings behind it against 2, so its average is the more settled of the two.

PiKuBo ships an update every 5 weeks, Bright Math every 4 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
