Verdict
The clearest difference is ads: memoryOS at none against Impulse's shown. memoryOS also leads on rating (4.9 vs 4.7) and review sentiment (80% vs 70%). Impulse's advantage is ratings volume (851K vs 17K) and update cadence (weekly vs every 2 weeks). On price, in-app purchases and monetization model 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. Impulse sells 14 in-app purchases, starting at $4.99 per 7 days and memoryOS sells 23 in-app purchases, starting at $3.99 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 4.7. That said, the two scores are not equally well evidenced: Impulse has 851K ratings behind it against 17K, so its average is the more settled of the two. Written reviews point the same way: 70% of Impulse's written reviews are positive against 80% of memoryOS's.
Impulse ships an update weekly, memoryOS every 2 weeks. Both last shipped on October 19, 2026.
