Verdict
The clearest difference is monetization model: X3 Force at free with in-app purchases against HarambeFit's subscription. X3 Force also leads on update cadence (fortnightly vs every 2 months) and review sentiment (70% vs 61%). HarambeFit's advantage is rating (4.5 vs 4.1) and ratings volume (152 vs 20). On price, ads, 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. X3 Force sells 2 in-app purchases, starting at $14.99 per month and HarambeFit sells 5 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.
HarambeFit holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: HarambeFit has 152 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 70% of X3 Force's written reviews are positive against 61% of HarambeFit's, so the app with the better star average is not the one people write more warmly about.
X3 Force ships an update fortnightly, HarambeFit every 2 months. The most recent releases landed on September 24, 2026 and September 20, 2026 respectively.
