# Readwise vs Certifyde

The clearest difference is ads: Readwise at none against Certifyde's shown. Readwise also leads on ratings volume (1.5K vs 15) and device support (3 vs 1). Certifyde's advantage is review sentiment (83% vs 72%). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Readwise sells 8 in-app purchases, starting at $4.99 per month and Certifyde sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Readwise against 4.7 for Certifyde. That said, the two scores are not equally well evidenced: Readwise has 1.5K ratings behind it against 15, so its average is the more settled of the two. Written reviews are what separate them: 72% of Readwise's written reviews are positive against 83% of Certifyde's.

Readwise ships an update every 2 weeks, Certifyde every 3 weeks. The most recent releases landed on October 3, 2026 and September 30, 2026 respectively.
