# Opto vs MediSearch AI

The clearest difference is rating: MediSearch AI at 4.7 against Opto's 3.0. MediSearch AI also leads on ratings volume (227 vs 2) and review sentiment (66% vs 50%). Opto's advantage is ads (none vs shown) and iOS requirement (12.1 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Opto sells 2 in-app purchases, starting at $34.99 per month and MediSearch AI sells 26 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

MediSearch AI holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: MediSearch AI has 227 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of Opto's written reviews are positive against 66% of MediSearch AI's.
