Verdict
The clearest difference is monetization model: Brain Dots at free with in-app purchases against Happy Glass's subscription. Happy Glass's advantage is ratings volume (99K vs 8.2K). On price, rating, review sentiment and update cadence 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. Brain Dots sells 10 one-off in-app purchases and Happy Glass sells 10 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Brain Dots holds the better App Store score, 4.4 against 4.3. That said, the two scores are not equally well evidenced: Happy Glass has 99K ratings behind it against 8.2K, so its average is the more settled of the two. Written reviews point the same way: 50% of Brain Dots's written reviews are positive against 49% of Happy Glass's.
Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on October 29, 2026.
