# PellaSchools vs UDBapp Pro

The clearest difference is ratings volume: UDBapp Pro at 2.4K against PellaSchools's 7. UDBapp Pro also leads on rating (4.8 vs 4.4) and update cadence (every 6 weeks vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

UDBapp Pro holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: UDBapp Pro has 2.4K ratings behind it against 7, so its average is the more settled of the two.

PellaSchools ships an update every 7 months, UDBapp Pro every 6 weeks. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
