# Curebase vs eResearch

The clearest difference is rating: Curebase at 5.0 against eResearch's 4.6. Curebase also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 15.1). eResearch's advantage is update cadence (every 5 weeks vs every 6 months) and ratings volume (75 vs 3). On price, ads, in-app purchases and device support there is nothing between them.

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

Curebase holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: eResearch has 75 ratings behind it against 3, so its average is the more settled of the two.

Curebase ships an update every 6 months, eResearch every 5 weeks. The most recent releases landed on September 24, 2026 and September 29, 2026 respectively.
