# CIRCUL RING vs BIDSleep

The clearest difference is rating: CIRCUL RING at 2.3 against BIDSleep's 2.0. CIRCUL RING also leads on ratings volume (34 vs 4) and iOS requirement (13.0 vs 16.0). BIDSleep's advantage is review sentiment (25% vs 13%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

CIRCUL RING holds the better App Store score, 2.3 against 2.0. That said, the two scores are not equally well evidenced: CIRCUL RING has 34 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 13% of CIRCUL RING's written reviews are positive against 25% of BIDSleep's, so the app with the better star average is not the one people write more warmly about.
