# Numera vs Bubble.Fill

The clearest difference is update cadence: Numera at every 6 days against Bubble.Fill's fortnightly. Numera also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Numera sells 10 one-off in-app purchases and Bubble.Fill sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Numera ships an update every 6 days, Bubble.Fill fortnightly. Both last shipped on November 8, 2026.
