Unlike a smart watch, you can be active and moving and get your ECG. -- Stryker50, 2025-03-06 ### ***** "Lush" Very nice and reassuring for my broken heart -- Inventory man, 2024-12-21 ### ***** "Dr T Petrov -review" Great app. It puts the physical training in a completely different level hearth wise. Thank you Fourthfrontier!🤘❤️ -- Toko🤘, 2024-11-20 ### *---- "Paywalled functionality" As a bleeding edge HRM there is an opportunity expectation that you are buying in to an ecosystem of continuous improvement. The high outlay cost is made with the understanding that innovation will take place and as effective beta users, you get access and enjoy new features. Unfortunately this isn’t the case. Despite a sub par application performance will minimal features and poor usability, they have went directly into a pay per view mode and introduced some features that might be interesting, are already provided by other HRM products but are asking for a “premium” subscription where those others don’t. If you want a continuous ECG capability, this does that. For everything else, get one a third of the price with all the other things for free. -- Aly 1999, 2024-10-17 ### ***** "Excellent bit of kit" Easy and intuitive to use and gives me all the data that I want including a detailed ECG. Very impressed. Only downside is the initial cost but spread over your active life it’s a really good investment -- Bobby Mimms cat, 2024-07-25 ### ***** "Later" Later -- Carl Hopkins, 2024-04-20 ### ***** "So far so good" I’ve had this for about a week and I’m finding it extremely easy to use and appears to be accurate. The information it provides is extremely useful in tracking heart health and fitness. -- Trooper7511, 2024-03-02 ### ***** "Amazing kit" Brilliant device and has given me some piece of mind. knowing my heart is not under undue strain takes a lot of the anxiety away -- DubiousFerret, 2023-09-19 ### ***** "Fantastic Product" This has transformed how I exercise focusing on being heart healthy. Amazing customer support and I had a 121 onboarding. Great product. -- MTombsy, 2023-09-02 ### ****- "Connection not the best" Love the function of app and data is great but device keeps disconnecting from the phone :) -- Team Sherriff, 2023-06-25 ### ***** "Sean" No QT interval showing why -- gnghgbbgdxf, 2023-05-05 ### ***** "Loads of info" If you want to see what’s going on, this will do it😀 -- Johnarzt, 2023-04-22 ### ***** "Does what it promises" (Cyclist) Syncs nicely with my Garmin bike computer, gives all the usual data - heart zones etc - plus a useful narrative summary of the training impact of an activity - with all the promised good quality ECG and strain / regularity metrics. Sometimes the ECG gets a bit noisy out of the saddle, up hills, but compares very favourably to a Holter monitor I once used. I've had 3 good rides from one charge so far. The logging in business some users describe and don't like is just making an account for the app and is actually quite straight forward. Overall: Very pleased with the device. -- David/N'cle, 2023-04-16 ### ***** "Awesome piece of kit" Helps me train reliably in the HR zones I need. I trust the data. Post event analysis is terrifically useful -- Nobbynor, 2023-02-19 ### ***** "The best wearable true ECG with heart strain going" If you have a heart condition but wish to keep fit then this is for you, train within limits breathing rate and heart strain and heart rate to maintain safe cardiovascular workouts. -- Pyreneenvic, 2023-02-10 ### ***** "Great tracking my heart & breathing" Love the HR monitor which is more than that. Works with a lot of useful data. The next step in managing your heart and health. Love that it syncs with Apple health and works directly via Strava. With my phone or watch it even provides route info fir walking, running and cycling. An A* modern but simple product & service so far. -- The_Mistry, 2022-11-12 ### ***** "Update problems" I’ve found the device and App excellent over the last year. Used today for first time after App update and it was useless. Only measured HR. Breathing rate showed 1 breath per minute! Other measures all failed PS the software problem was quickly solved and all is good now -- Lenchchris, 2022-11-09 ### ***** "New HR monitor" I was concerned that recent abnormal performance may be cardiac related, hoped it was only post Covid issues, pondered the Frontier X for a while and decided to take the plunge, so pleased I did. The ecg is excellent, as a vet of 30 years experience I have an advantage in being able to get more from the interpretation but it’s so much more valuable than what my previous monitor was able to provide. The reassurance that there wasn’t a cardiac aetiology to my symptoms has been a huge weight off my mind and as oft happens the performance has improved dramatically too. All round very happy customer. So far a very easy to use and reliable bit of kit. Thank you -- Jules Rish, 2022-10-16 ### ***** "Awesome piece of gear!" Makes a huge difference to training.. -- drtewqui, 2022-09-18 [View all Frontier X reviews and detailed analytics on AppTail](https://apptail.io/ru/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Frontier X In-App Purchases | Item | Price | |------|-------| | Monthly | £13.99 | | Yearly | £109.99 | ## Apps Similar to Frontier X -
