# True Color vs Ring Stack

The clearest difference is in-app purchases: True Color at none against Ring Stack's 1. True Color also leads on ads (none vs shown). Ring Stack's advantage is ratings volume (18 vs 2) and iOS requirement (12.0 vs 18.5). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. Ring Stack sells 1 one-off in-app purchase. True Color asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for True Color against 4.9 for Ring Stack. That said, the two scores are not equally well evidenced: Ring Stack has 18 ratings behind it against 2, so its average is the more settled of the two.

True Color ships an update every 6 weeks, Ring Stack every 5 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
