Rubber Bands builds resistance band workouts around the bands you own. It picks the band and reps for every set, and tells you when to move up. Add your bands once. Every workout after that is built from them. THE BAND AND REPS FOR EVERY SET • Each exercise comes with the band to use and the reps to hit, matched to your level and your goal • Automatic mode builds a workout from the muscle groups you pick and the bands you have • Build your own workouts too, or start from routines like Push/Pull/Lower and Upper/Lower KNOW WHEN TO MOVE UP • Progression reads your recent sessions of each exercise • Hit the top of your rep range in two of your last three sessions, and it suggests the next band up • When the next band is too big a jump, it can suggest stacking two bands instead MADE FOR RESISTANCE BANDS • Bands are first-class equipment, each with its own resistance range, not an afterthought on a gym plan • Gym profiles for home, hotel and office, each with the bands and anchors you have there • Built for loop bands, and it works with tube bands and loop bars like X3 and Harambe too • Bands from any brand, from the built-in catalog or added as your own • Band-assisted moves like pull-ups and dips TRACK EVERY REP • Sets, reps and the band you used, logged as you go • Personal records, including the first time you use a new band • Charts, streaks and a full workout log • Log sets from your Apple Watch with your phone in your pocket • A rest timer between sets • Works offline: your workouts and history are stored on your phone • Syncs with Apple Health and Strava FREE TO START Add your bands, try full workouts and track every set for free.

Verdict
The clearest difference is rating: Rubber Bands at 4.7 against X3 Force's 4.1. Rubber Bands also leads on ratings volume (134 vs 21). X3 Force's advantage is monetization model (free with in-app purchases vs subscription) and ads (none vs shown). On price, review sentiment, update cadence 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. X3 Force sells 2 in-app purchases, starting at $14.99 per month and Rubber Bands sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Rubber Bands holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Rubber Bands has 134 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 70% of X3 Force's written reviews are positive against 68% of Rubber Bands's, so the app with the better star average is not the one people write more warmly about.
X3 Force ships an update fortnightly, Rubber Bands every 10 days. The most recent releases landed on October 11, 2026 and October 23, 2026 respectively.
