# Dosing Pump 2 vs Smart Reef

The clearest difference is rating: Smart Reef at 1.6 against Dosing Pump 2's 1.0. Smart Reef also leads on ratings volume (19 vs 2). Dosing Pump 2's advantage is in-app purchases (none vs 11) and review sentiment (16% vs 4%). On price, ads and device support there is nothing between them.

Both are free to download. Smart Reef sells 8 one-off in-app purchases. Dosing Pump 2 asks for nothing beyond the download.

Smart Reef holds the better App Store score, 1.6 against 1.0. That said, the two scores are not equally well evidenced: Smart Reef has 19 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 16% of Dosing Pump 2's written reviews are positive against 4% of Smart Reef's, so the app with the better star average is not the one people write more warmly about.

Dosing Pump 2 ships an update every 5 weeks, Smart Reef every 3 months. The most recent releases landed on June 2, 2026 and September 26, 2026 respectively.
