Verdict
The clearest difference is in-app purchases: ErgData at none against Wolf Pack Fit's 1. ErgData also leads on ratings volume (6.4K vs 5) and rating (4.7 vs 4.4). Wolf Pack Fit's advantage is review sentiment (75% vs 47%). On price, ads, 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. Wolf Pack Fit sells 1 in-app purchase, starting at $29.99 per month. ErgData asks for nothing beyond the download.
ErgData holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: ErgData has 6.4K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 47% of ErgData's written reviews are positive against 75% of Wolf Pack Fit's, so the app with the better star average is not the one people write more warmly about.
ErgData ships an update fortnightly, Wolf Pack Fit every 2 months. The most recent releases landed on November 9, 2026 and October 30, 2026 respectively.
