# Hatch Grow vs Which Boob?

Hatch Grow and Which Boob? both sit at 4.8 stars, but that hides the real split: 92% of Which Boob?'s written reviews are positive against 33% of Hatch Grow's. Which Boob? also leads on update cadence (fortnightly vs every 2 months). Hatch Grow's advantage is ratings volume (13K vs 49) 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. Neither carries in-app purchases, so what you see is what you pay.

Hatch Grow holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Hatch Grow has 13K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 33% of Hatch Grow's written reviews are positive against 92% of Which Boob?'s, so the app with the better star average is not the one people write more warmly about.

Hatch Grow ships an update every 2 months, Which Boob? fortnightly. Both last shipped on November 11, 2026.
