# Coolki¹ vs Bubble Link

The clearest difference is in-app purchases: Coolki¹ at none against Bubble Link's 11. Coolki¹ also leads on ads (none vs shown) and review sentiment (79% vs 66%). Bubble Link's advantage is ratings volume (5.6K vs 64) and rating (4.9 vs 4.6). On price and device support there is nothing between them.

Both are free to download. Bubble Link sells 11 one-off in-app purchases. Coolki¹ asks for nothing beyond the download.

Bubble Link holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Bubble Link has 5.6K ratings behind it against 64, so its average is the more settled of the two. Written reviews complicate that: 79% of Coolki¹'s written reviews are positive against 66% of Bubble Link's, so the app with the better star average is not the one people write more warmly about.

Coolki¹ ships an update every 2 months, Bubble Link fortnightly. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
