Verdict
The clearest difference is in-app purchases: Emerald Mine at none against Pac.io's 10. Emerald Mine also leads on ads (none vs shown) and iOS requirement (10.0 vs 13.0). Pac.io's advantage is rating (4.2 vs 4.0) and ratings volume (297 vs 32). On price, review sentiment, update cadence 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. Pac.io sells 10 one-off in-app purchases. Emerald Mine asks for nothing beyond the download.
Pac.io holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Pac.io has 297 ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 55% of Emerald Mine's written reviews are positive against 54% of Pac.io's, so the app with the better star average is not the one people write more warmly about.
Emerald Mine ships an update every 2 weeks, Pac.io fortnightly. The most recent releases landed on September 20, 2026 and September 21, 2026 respectively.
