User reviews

Great potential but….complex connectivity zero support.

Love the intentions but the app is cumbersome the connectivity very fragile and in consistent. Analysis shows data that is not on the dash board. Paring with HRMs also inconsistent and unreliable if the monitor is in use by any other app/ device. My big bugbear is the battery retention, use one and leave it with 60% return a week later and the battery is dead and the fact it’s a unique adaptor is also a pain.i like the direction it’s sending me it’s just the journey is not as enjoyable and easy as it should be data captured on a Wahoo missed by this app, as such no value in wearing. Garbage is my last eat opinion .

Potential not realized

I’ve been using the core 2 for over a year. This app is half baked. Connection to the core 2 sensor can be very frustrating. There is significant lag with readings. I often use the app to track my heat strain in real time, but the app doesn’t reliably tabulate either time in zone. I’ve been riding for an hour as I write this and all the zones on the histogram say zero. The daily heat training bar also says zero. So you can’t use a daily heat training load as a daily end point for your training. Also, when logging passive heat training, it would be nice if it calculated how much time you needed to spend doing each activity to achieve a particular daily heat training load. E.g. based on the ride I’m doing now, it would be nice if the app told me I had to do 20 minutes of sauna to achieve the daily heat load of 10.

Buggy and hard to get hold of support

Won’t connect reliably with tp link Bluetooth adapter and disconnects from Zwift if companion app is in background unlike other Bluetooth sensors.

Don’t waste your time

Attempted to purchase one of these to track body temp while training. On 2 attempts core failed to ship the device in a timely manner or at all. Waited weeks on both attempts to get the device only to hear excuses like it was shipped back “we’re not sure why”. For the money they’re asking for this, it’s not worth it.

FAQ

What does the CORE Thermal Sensor app do?

The CORE Thermal Sensor app continuously measures your core body temperature and thermal strain. This data is crucial for optimizing heat training, improving performance during races, and understanding how your body responds to heat.

What are the key features of the CORE app?

Key features include continuous core body temperature monitoring, a real-time Heat Strain Index, Heat Zones to guide training and racing, Heat Training Load and Adaptation Scores, and the ability to track passive heat training. It also offers data trend analysis and connectivity with other sports devices.

Is the CORE Thermal Sensor app free to use?

Based on the provided information, the CORE app is free to use. However, it requires the CORE device, which must be ordered separately from their website.

What devices is the CORE app compatible with?

The CORE app is designed to work with the CORE device. It also allows you to connect your heart rate monitor and other sports devices, such as Garmin, for optimal sensor use and data synchronization.

How can the CORE app help with heat training?

The app provides insights into your core body temperature and thermal strain, allowing you to strategically train in Heat Zone 3 to build adaptations. It also tracks your Heat Training Load and Heat Adaptation Score to ensure you are effectively preparing for heat exposure and performing optimally.
