# Open vs Plumm

The clearest difference is in-app purchases: Plumm at none against Open's 2. Plumm also leads on iOS requirement (15.0 vs 17.0). Open's advantage is ratings volume (18K vs 1) and update cadence (weekly vs monthly). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Open sells 2 in-app purchases, starting at $19.99 per month. Plumm asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Open against 5.0 for Plumm. That said, the two scores are not equally well evidenced: Open has 18K ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 60% of Open's written reviews are positive against 67% of Plumm's.

Open ships an update weekly, Plumm monthly. The most recent releases landed on October 28, 2026 and October 27, 2026 respectively.
