# i vs Professional Marimba

The clearest difference is ads: i at none against Professional Marimba's shown. i also leads on iOS requirement (12.0 vs 15.0). Professional Marimba's advantage is ratings volume (15 vs 2) and update cadence (every 3 months vs every 7 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. i sells 4 one-off in-app purchases and Professional Marimba sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for i against 4.5 for Professional Marimba. That said, the two scores are not equally well evidenced: Professional Marimba has 15 ratings behind it against 2, so its average is the more settled of the two.

i ships an update every 7 months, Professional Marimba every 3 months. The most recent releases landed on November 1, 2026 and November 4, 2026 respectively.
