# Simpli Soda CO2 Refills vs UniFi Store

The clearest difference is rating: Simpli Soda CO2 Refills at 4.7 against UniFi Store's 3.4. Simpli Soda CO2 Refills also leads on ratings volume (2.1K vs 37) and iOS requirement (15.1 vs 18.0). UniFi Store's advantage is ads (none vs shown) and update cadence (fortnightly vs every 11 months). On price, in-app purchases and device support there is nothing between them.

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

Simpli Soda CO2 Refills holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Simpli Soda CO2 Refills has 2.1K ratings behind it against 37, so its average is the more settled of the two. Written reviews complicate that: 34% of Simpli Soda CO2 Refills's written reviews are positive against 44% of UniFi Store's, so the app with the better star average is not the one people write more warmly about.

Simpli Soda CO2 Refills ships an update every 11 months, UniFi Store fortnightly. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
