# CO vs WeWear

The clearest difference is ads: WeWear at none against CO's shown. WeWear also leads on rating (5.0 vs 4.5) and monetization model (free vs ad-supported). CO's advantage is ratings volume (1.2K vs 2) and update cadence (fortnightly vs every 5 weeks). 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.

WeWear holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: CO has 1.2K ratings behind it against 2, so its average is the more settled of the two.

CO ships an update fortnightly, WeWear every 5 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
