# TrialKit vs eResearch

The clearest difference is review sentiment: eResearch at 90% against TrialKit's 40%. eResearch also leads on rating (4.6 vs 3.8) and ratings volume (75 vs 13). TrialKit's advantage is monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases 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, 4.6 against 3.8. That said, the two scores are not equally well evidenced: eResearch has 75 ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 40% of TrialKit's written reviews are positive against 90% of eResearch's.

TrialKit ships an update every 3 weeks, eResearch every 5 weeks. The most recent releases landed on September 15, 2026 and September 24, 2026 respectively.
