We are pleased to announce the new Jaquish Biomedical X3® Force! X3 Force is an electronic, force tracking X3 bar that works with a smartphone application to display and record real time data about each exercise session. With X3 Force, you can get the benefits of a smart home gym, combined with the superior X3 variable resistance workout methodology. With every workout, you'll compete with your previous Total Force, a performance metric that uses real-time force data to calculate time under variable tension and overall workout quality. This way you will always know you're stimulating more growth. X3 Force combines force data with time and rep count information to calculate a Total Force exercise rating, that helps to summarize the difficulty and quality of each exercise session, so that you can more conveniently track your improvement. Focusing on improving your Total Force for each exercise is a great way to confirm that you are maximizing your results and adhering to X3 best practices. Maximize your results with data-driven workouts to help you push harder and perform better each time. With X3 Force you can: * View Peak Forces For Every Exercise * Quantify Overall Workout Quality * Record Workout Duration * Monitor Rep Consistency * Calculate Time Under Variable Tension Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ## Key features - Real-time force tracking - Quantify workout quality - Record workout duration - Monitor rep consistency - Calculate time under tension - View peak forces ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Monthly | $14.99 | per month | | Yearly | $164.99 | per year | ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/x3-force/id1571190223/reviews.md ### 4/5 — Terrific potential could be truly great *2026-08-02* This gamifies the workouts in a way that is very motivating. The AI assist keeps prompting you on form and progression and the data tools are sound for tracking. You want to generate more force and you have proof vs just a feeling of progression. This app needs a lifetime access tier based on one time purchase or as a recognition of historic x3 patronage (total dollar spend from a user acct perhaps for those who’ve bought varied iterations, supplements, accessories etc). The app also needs to allow for at least two concurrent users programmed in on the same account and app for couples so it simply swaps during the workout if not a family plan with a limit of 3-4. My wife and I share grocery lists and schedule across apps would love something as important as our fitness to do so too so we can smoothly swap between during sets/rest respectively. I know recurring revenue is important for a company but this would be a big satisfier for longtime loyal x3 users. ### 5/5 — Great app needs a tweak *2026-05-28* Great system and app! ### 1/5 — App stinks *2026-01-21* I’m subscribed, but the app tells me I’m not? So what am I paying for every month? **Developer response:** Hello! We are sorry you are experiencing this problem. If you have not already, please contact us at cs@jaquishbiomedical.com and we can help you resolve this issue! ### 2/5 — X3 Force Tracking *2025-09-24* This app is extremely limited in its scope. It can only track a select few exercises. I like to track everything and it would be nice if the hooks could measure anything on the app even if just for comparison purposes from day to day. Additionally, the app is pro e to bugs and I have been unable to track exercises for about a week. All I hear is that they are working on it but have received radio silence about still being charged for the app while it is not working. The fee is much too high for the limited capabilities of the system. ### 5/5 — Outstanding app equipment *2024-12-28* Best way to track and more importantly inspire progress. Perfect! ### 5/5 — Great experience with the X3 Force Bar *2024-09-10* The app is the perfect companion for the X3 Force bar to show you all your data in real time including reps, force, and time. It’s fun to go back and see how much you have progressed in each workout or individual exercise. I have also utilized the recent “Demo” mode to show an interested party. Glad Jaquish Biomedical continues to support the app with updates and improvements! ### 5/5 — Excellent *2024-07-05* Great product and great customer support ### 1/5 — Returning Equipment *2024-04-08* Spent $1,000 for equipment with an app that doesn’t work. Don’t know why companies do this. Very frustrating. I’ll be returning the equipment. ### 5/5 — Great Companion to the X3 Force Bar *2024-03-05* This works with the X3 Force bar to measure the force you’re exerting in realtime. The pickup of data over Bluetooth works extremely well, and I love seeing the curve react to my reps LIVE. It’s a nice visual reminder to slow down and create a smooth motion throughout the rep. I would love the app to have an option to throw an on-screen warning at me if it detects a rep being done when I haven’t yet selected an exercise, as I sometimes forget to do so. My biggest gripe with the app was recently resolved: previously you could only see the combined total force in the charts, meaning in the longer date ranges (like YTD) all of the force in any given month was being totaled together, which was not helpful to me at all when trying to view my strength gains over time, because I rarely worked out the same number of times every month. Now you are able to view the highest force in each time period, which is much more helpful. I would love to see an option for the “average” force too. I’m happy to see that Dr. J and the team are continuing to build out and improve the app with regular updates. Excited for future updates! ### 5/5 — Outstanding *2023-05-19, version 1.0.7* The bar is expensive but the data super helpful ## Frequently asked questions about X3 Force ### What is X3 Force?
