# 51CTO vs Mimo

The clearest difference is ads: 51CTO at none against Mimo's shown. 51CTO also leads on monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 18.0). Mimo's advantage is review sentiment (71% vs 41%) and chart position (#92 vs unranked). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. 51CTO sells 23 one-off in-app purchases and Mimo sells 12 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

51CTO ships an update fortnightly, Mimo weekly. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
