# Bowelle vs Nerva

Bowelle and Nerva both sit at 4.7 stars, but that hides the real split: 92% of Bowelle's written reviews are positive against 73% of Nerva's. Nerva's advantage is chart position (#148 vs unranked) and update cadence (weekly vs fortnightly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Bowelle sells 9 in-app purchases, starting at $2.49 per month and Nerva sells 4 in-app purchases, starting at $43.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Bowelle against 4.7 for Nerva. That said, the two scores are not equally well evidenced: Nerva has 15K ratings behind it against 2.2K, so its average is the more settled of the two. Written reviews are what separate them: 92% of Bowelle's written reviews are positive against 73% of Nerva's.

Bowelle ships an update fortnightly, Nerva weekly. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
