# EpiDiary vs EpiCentr

The clearest difference is in-app purchases: EpiDiary at none against EpiCentr's 8. EpiCentr's advantage is ratings volume (1.7K vs 47) and review sentiment (59% vs 42%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. EpiCentr sells 8 in-app purchases, starting at $15.99 per month. EpiDiary asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.4 for EpiDiary against 4.5 for EpiCentr. That said, the two scores are not equally well evidenced: EpiCentr has 1.7K ratings behind it against 47, so its average is the more settled of the two. Written reviews are what separate them: 42% of EpiDiary's written reviews are positive against 59% of EpiCentr's.
