# ARBA vs Co

The clearest difference is review sentiment: Co at 75% against ARBA's 33%. Co also leads on in-app purchases (none vs 5) and update cadence (every 3 months vs every 12 months). ARBA's advantage is ads (none vs shown) and rating (4.6 vs 4.3). On price, device support and iOS requirement there is nothing between them.

Both are free to download. ARBA sells 5 one-off in-app purchases. Co asks for nothing beyond the download.

ARBA holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: ARBA has 357 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 33% of ARBA's written reviews are positive against 75% of Co's, so the app with the better star average is not the one people write more warmly about.

ARBA ships an update every 12 months, Co every 3 months. The most recent releases landed on September 13, 2026 and June 4, 2026 respectively.
