# Bébé Signe vs Sign3D

The clearest difference is update cadence: Sign3D at fortnightly against Bébé Signe's every 5 months. Sign3D also leads on monetization model (free vs free with in-app purchases) and review sentiment (100% vs 91%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Bébé Signe sells 10 one-off in-app purchases and Sign3D sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Bébé Signe ships an update every 5 months, Sign3D fortnightly. The most recent releases landed on July 27, 2026 and September 6, 2026 respectively.
