Verdict
The clearest difference is in-app purchases: Get My IDFA at none against Happy's 1. Get My IDFA also leads on review sentiment (83% vs 71%). Happy's advantage is ads (none vs shown) and update cadence (weekly vs every 19 months). On price, chart position, 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. Happy sells 1 in-app purchase, starting at $19.99 per month. Get My IDFA asks for nothing beyond the download.
Happy holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Happy has 991 ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 83% of Get My IDFA's written reviews are positive against 71% of Happy's, so the app with the better star average is not the one people write more warmly about.
Get My IDFA ships an update every 19 months, Happy weekly. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
