Verdict
The clearest difference is ads: RANDOM.ORG at none against Pretty Random's shown. RANDOM.ORG also leads on monetization model (free vs free with in-app purchases) and ratings volume (1.3K vs 306). Pretty Random's advantage is review sentiment (74% vs 59%) and update cadence (every 6 weeks vs every 3 months). On price, rating, 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. RANDOM.ORG sells 6 one-off in-app purchases and Pretty Random sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
RANDOM.ORG holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 1.3K and 306 respectively. Written reviews complicate that: 59% of RANDOM.ORG's written reviews are positive against 74% of Pretty Random's, so the app with the better star average is not the one people write more warmly about.
RANDOM.ORG ships an update every 3 months, Pretty Random every 6 weeks. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
