Verdict
The clearest difference is ratings volume: Calflow at 131 against 线岛's 1. 线岛's advantage is review sentiment (100% vs 89%). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calflow sells 3 in-app purchases, starting at $3.99 per month and 线岛 sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for Calflow against 5.0 for 线岛. That said, the two scores are not equally well evidenced: Calflow has 131 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 89% of Calflow's written reviews are positive against 100% of 线岛's.
Calflow ships an update every 10 days, 线岛 every 9 days. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
