Verdict
The clearest difference is monetization model: Draw Fun at free with in-app purchases against Happy Glass's subscription. Draw Fun also leads on update cadence (every 3 days vs every 3 weeks) and rating (4.5 vs 4.3). Happy Glass's advantage is ratings volume (99K vs 19K). On price, ads, in-app purchases and device support 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. Happy Glass sells 10 in-app purchases, starting at $7.99 per 7 days and Draw Fun sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Draw Fun holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Happy Glass has 99K ratings behind it against 19K, so its average is the more settled of the two. Written reviews point the same way: 49% of Happy Glass's written reviews are positive against 59% of Draw Fun's.
Happy Glass ships an update every 3 weeks, Draw Fun every 3 days. Both last shipped on November 4, 2026.
