The SmartCuffs app is designed to connect to your SmartCuffs 4.0 devices. Blood Flow Restriction (BFR) training is a technique in which combines low-intensity exercise under reduced arterial flow conditions. BFR is quantifiably and objectively reducing the amount of blood flow into an extremity by using a specially made medical tourniquet. BFR allows individuals to use low loads yet achieve results similar to high intensity training. The SmartCuffs 4.0 is the only wireless BFR cuff in the world that contains our TriPressure technology. This allows for 3 types of evidenced-based, research supported BFR (continuous, intermittent, and resting BFR). ## Key features - Connects to SmartCuffs 4.0 devices - Enables Blood Flow Restriction (BFR) training - Supports low-intensity exercise - Utilizes TriPressure technology - Offers continuous BFR - Offers intermittent BFR - Offers resting BFR ## Recent user reviews (10 of 23) All indexed reviews: https://appshunter.io/ios/app/smartcuffs/id1632227731/reviews.md ### 2/5 — Wireless connection is horrible *2026-06-28* This app never wants to connect to the bands. It takes forever over multiple tries to connect. It’s only useable to get the bands to standalone mode. ### 1/5 — Overhyped *2026-05-16* Right out of the box these cuffs were very difficult to connect. I got errors once they were connected and when they tried to inflate they failed. Pressing the emergency stop button did absolutely nothing. For 900.00 this product should work flawlessly and the construction of these makes me wonder if they will last a year. A user opens the box gets started and immediately has issues. Not a good first impression and a huge let down after spending so much money. I am considering returning these and going to another brand. I was excited to get these now it’s womp womp. Do better guys. ### 5/5 — Works incredibly well *2026-04-26* I noticed that this is the brand my Physical Therapist was using so I bought a pair for myself. Nice to have peace of mind that it’s able to adjust to what my body needs as far as the amount of tightness. After 3 weeks, my left knee is getting less and less achy because my left quad has improved so much over that short period of time. I’m also noticing a very quick progression in strength and size there and when I use the arm bands to do push-ups, both in my arms and in my chest. This has revolutionized my martial arts training by helping me get past the weak foundation from my knee and has helped majorly with kata and normal everyday techniques. Because this tech was developed originally in regards to older people, I’ve been able to recommend it to my aging parents to help with some of their muscular problems, to help give them a firmer foundation for everyday life. Great for people who don’t have the time to get to a gym or don’t have access to heavier weights. There are lots of pointers and tools on the SmartTools website for exercises and safety. Thanks SmartTools! ### 1/5 — Updated firmware bricked my cuffs *2026-03-23* Updated one cuff, plugged in near the others. Worked for a few days now they won’t turn on. Reached out to customer service let’s see what they say - fyi to those thinking about updating ### 1/5 — New app version is unusable. *2026-03-16* Update is completely unusable. Takes forever to load fails to load client lists gifts for more update issues without there being a new firmware available needs to be fixed ASAP ### 3/5 — Great quality cuffs tech need work *2026-01-20* Would be 5star easy if app worked. Likes to disconnect while saving sets which I learned to not even do that. Just pay attn to timer and keep track of sets that way. It wouldn’t disconnect during your session. Now it likes to disconnect after saving sets which and then cuff would change color. So now you have to go though whole process again. So tech needs work but overall cuff is made of good quality ### 1/5 — Sketchy Bluetooth connection *2026-01-18* Honestly wanted to love these. Loved the intention of the app. But it just doesn’t work. Do not spend the money. Find a brand that gets this whole package right. Cuff. Bluetooth. App. Too many other options to settle for this. ### 1/5 — Disconnect *2025-12-04* Compared to how much these cost, the app is a joke and poorly made. The biggest issue is that if it disconnects from your cuffs, it resets your whole workout times. It’s such a simple fix that they seem to refuse to do. I would not recommend the 4.0 cuffs until they tighten their app up a lot more. ### 1/5 — Can’t connect to bluetooth *2025-04-29* Can’t connect to bluetooth ### 1/5 — Terrible connection *2024-12-14* I love Smartcuffs. I purchased the 4.0 because no other generation was available for purchase at that time. This app is terrible. The cuffs constantly lose connection with the app. This results in numerous problems including failure to calibrate (with no alternate option to enter a manual LOP) and interruption of workouts. I wish I could have purchased the 3.0 and take the app out of the equation. I’m not going to pay for another set of cuffs. This is a fantastic company, but the app needs to get with it. ## Frequently asked questions about SmartCuffs ### What does the SmartCuffs app do?
