Verdict

The call

The clearest difference is rating: EMDR at 4.4 against Bumble BLS's 3.8. EMDR also leads on update cadence (every 4 days vs every 4 weeks) and ratings volume (173 vs 6). Bumble BLS's advantage is in-app purchases (none vs 6) and review sentiment (60% vs 46%). On price and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

EMDR holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: EMDR has 173 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 46% of EMDR's written reviews are positive against 60% of Bumble BLS's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

EMDR ships an update every 4 days, Bumble BLS every 4 weeks. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
