# Rectifi vs CenterMint

The clearest difference is ads: Rectifi at none against CenterMint's shown. Rectifi also leads on ratings volume (23 vs 1). CenterMint's advantage is update cadence (every 4 days vs every 11 days). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Rectifi sells 1 in-app purchase, starting at $7.99 per month and CenterMint sells 2 in-app purchases, starting at $2.99 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 — 5.0 for Rectifi against 5.0 for CenterMint. That said, the two scores are not equally well evidenced: Rectifi has 23 ratings behind it against 1, so its average is the more settled of the two.

Rectifi ships an update every 11 days, CenterMint every 4 days. Both last shipped on October 24, 2026.
