Verdict
The clearest difference is update cadence: RiseGuide at every 4 days against memoryOS's every 3 weeks. memoryOS's advantage is rating (4.9 vs 4.6). 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. memoryOS sells 20 in-app purchases, starting at $3.99 per 7 days and RiseGuide sells 5 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
memoryOS holds the better App Store score, 4.9 against 4.6. Both are backed by a comparable volume of ratings — 16K and 19K respectively. Written reviews complicate that: 80% of memoryOS's written reviews are positive against 85% of RiseGuide's, so the app with the better star average is not the one people write more warmly about.
memoryOS ships an update every 3 weeks, RiseGuide every 4 days. Both last shipped on September 24, 2026.
