Verdict
The clearest difference is update cadence: PageEcho at every 3 days against Mythos's every 2 weeks. Mythos's advantage is rating (4.2 vs 4.0) and iOS requirement (15.1 vs 26.0). On price, review sentiment, ratings volume 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. Mythos sells 2 in-app purchases, starting at $9.99 per month and PageEcho sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Mythos holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 6 and 6 respectively. Written reviews complicate that: 86% of Mythos's written reviews are positive against 93% of PageEcho's, so the app with the better star average is not the one people write more warmly about.
Mythos ships an update every 2 weeks, PageEcho every 3 days. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
