Verdict

The call

The clearest difference is rating: Bunk1 at 4.2 against BLÜ's 3.5. Bunk1 also leads on ratings volume (487 vs 17). BLÜ's advantage is update cadence (fortnightly vs every 2 months) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Bunk1 holds the better App Store score, 4.2 against 3.5. That said, the two scores are not equally well evidenced: Bunk1 has 487 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 46% of Bunk1's written reviews are positive against 55% of BLÜ's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bunk1 ships an update every 2 months, BLÜ fortnightly. Both last shipped on November 6, 2026.
