Verdict
The clearest difference is rating: Happy Differences at 4.8 against Differences+'s 4.2. Happy Differences also leads on ratings volume (4.2K vs 5) and update cadence (every 5 weeks vs every 6 months). Differences+'s advantage is review sentiment (92% vs 56%) and ads (none vs shown). On price, in-app purchases, monetization model 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. Differences+ sells 1 one-off in-app purchase and Happy Differences sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Happy Differences holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Happy Differences has 4.2K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 92% of Differences+'s written reviews are positive against 56% of Happy Differences's, so the app with the better star average is not the one people write more warmly about.
Differences+ ships an update every 6 months, Happy Differences every 5 weeks. The most recent releases landed on October 8, 2026 and October 7, 2026 respectively.
