# Research Hive vs eResearch

The clearest difference is monetization model: Research Hive at free against eResearch's free with in-app purchases. Research Hive also leads on review sentiment (100% vs 90%). eResearch's advantage is ratings volume (85 vs 8). On price, rating, update cadence and ads there is nothing between them.

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

eResearch holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: eResearch has 85 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 100% of Research Hive's written reviews are positive against 90% of eResearch's, so the app with the better star average is not the one people write more warmly about.

Research Hive ships an update every 2 months, eResearch every 5 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
