# Hi vs Certifyde

The clearest difference is in-app purchases: Hi at none against Certifyde's 9. Hi also leads on rating (5.0 vs 4.7) and device support (3 vs 1). Certifyde's advantage is update cadence (every 6 weeks vs every 7 months) and ratings volume (15 vs 1). On price and ads there is nothing between them.

Both are free to download. Certifyde sells 9 one-off in-app purchases. Hi asks for nothing beyond the download.

Hi holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Certifyde has 15 ratings behind it against 1, so its average is the more settled of the two.

Hi ships an update every 7 months, Certifyde every 6 weeks. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
