Verdict
The clearest difference is review sentiment: Digly at 83% against RockHoundR's 42%. RockHoundR's advantage is rating (4.7 vs 4.2) and ratings volume (149 vs 6). On price, update cadence, ads and in-app purchases 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. RockHoundR sells 4 in-app purchases, starting at $6.99 per month and Digly sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
RockHoundR holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: RockHoundR has 149 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 42% of RockHoundR's written reviews are positive against 83% of Digly's, so the app with the better star average is not the one people write more warmly about.
RockHoundR ships an update every 9 days, Digly every 2 weeks. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
