Verdict
The clearest difference is rating: DSM at 4.7 against Psych Lab 101's 2.5. DSM also leads on ratings volume (308 vs 2) and update cadence (every 4 months vs every 13 months). Psych Lab 101's advantage is in-app purchases (none vs 2) and review sentiment (50% vs 33%). On price, ads, device support and iOS requirement 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. DSM sells 2 in-app purchases, starting at $24.99 per month. Psych Lab 101 asks for nothing beyond the download.
DSM holds the better App Store score, 4.7 against 2.5. That said, the two scores are not equally well evidenced: DSM has 308 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Psych Lab 101's written reviews are positive against 33% of DSM's, so the app with the better star average is not the one people write more warmly about.
Psych Lab 101 ships an update every 13 months, DSM every 4 months. The most recent releases landed on October 7, 2026 and October 22, 2026 respectively.
