Great idea, bad execution

I use Core each time I exercise and upload sauna sessions as well. Works great.

Except: the connectivity is bad, often need to kill the app to get a connection via Bluetooth, and the HRM sometimes drops too without any apparent reason.

Fix the connectivity issues and this gets 5 stars from me

No longer records time in heat zones = no adaptation score

Just like the title says. Using the previous generation of the core sensor and since the last iOS update the app no longer records time in heat zones. Without this you will have no idea what your heat adaptation score is. The sensor records to my head unit, Karoo Hammerhead 2, but the head unit does not have the ability to track Heat Strain Index. I can see Core temp and Skin Temp in training peaks but the last time I checked Training Peaks Does not account for HSI which is ironic considering that Training Peaks Virtual does. There is NO DOUBT in my mind that heat training works but if you. It into the core platform remember it’s not a set and forget technology and you will need to look at the data closely now that the application is broken.

Don”t Buy

The app and the products are very problematic! They don’t work at all

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.

Cannot get past setup screen

IOS 26
Cannot even get past the initial setup. Just get Failed to Save Preferences no matter what I choose.

何回トライしてもセンサーをスキャンできません。
センサー高かったのに、、、

App can not to open up

The app can not to open up normally.

全く使えない

データが全く正確に反映されません。
センサーは良いのにアプリはゴミです

They’re good at accepting your payment. So far, nothing else.

I’ve placed my order four days ago. It hadn’t shipped yet. They haven’t replied to any of my messages. So far, this smells like pure techbro hype: they over promise and don’t deliver. But maybe the product will be fantastic. Assuming it gets to me…

Could be great!

Useful training tool let down by a slow app.

The live metrics seem to work but the time in zone, heat training load and heat adaption score can be very slow to update for some reason. Surely this is an easy fix!

New sensort

I just changed to the new sensor. Everything was fine with the old one but now the data from todays ride/effort is not transfered to my « overall heat score ». It just stays at 0. It feels like lates UI update about a month or two ago doesn’t work well

Loss of data

App is sometimes losing or not using data from the day before to calculate the heat adaption.

Added passive, doesnt work

The adding of passive heat is great but setting the date doesn’t work…

Work in progress

This app leaves something to be desired. After initial download it signaled that an update was needed. The update would not download despite connection with a rapid local network. Multiple attempta at different times eventually resulted in success. Interaction with customer service was also frustratingly slow. Caveat emptor

Great product ruined by app

The product itself is revolutionary. But the app ‘experience’ is horrifying. Can’t justify upgrading device until app is fixed. But it seems to get worse, not better. Buggy, laggy, etc

全然ダメ

アプリ起動しても設定エラーするし、Bluetoothも繋がらない。
カスタムセンターに質問しても全然ダメ。
ちなみにセンサーは問題無し。

So teuer und lang am Markt und noch aus der Schweiz aber kann nichts richtig

Ich versuche, mich noch human auszudrücken und beschreibe es jetzt mal als große Enttäuschung… Wollte das Teil schon vor ein paar Monaten kaufen, haben mich aber gefragt für was… Jetzt wo ich das Teil habe und es gerne auf der Arbeit tragen wollte und auch mal meinen Schlaf kontrollieren und vielleicht auch hier und mal zum Radfahren, weil ich gehört habe, dass man es im Schlaf tragen kann habe ich mich dafür entschieden

Erst mal kam das Teil an und war tiefen entladen. Nach 8 Stunden aufladen hatte es dann 79 % und konnte eine halbe Stunde Update laden.
Das Teil ist gefühlt nach 5 Minuten wieder entkoppelt und zeichnet nichts auf

Noch dazu ist es zwingend notwendig einen Herzfrequenzmesser zu besitzen, was ich mal gar nicht verstehe
Davon habe ich vorher nichts gewusst, sonst hätte ich sofort die Finger davon gelassen

Aber laut Verpackung soll es ja auch mit der Apple Watch funktionieren
Die zwei vertragen sich aber mal überhaupt nicht… Keinerlei Verbindung herstellbar

Hab mir einen Brustgurt geliehen von Wahoo
Dem vertraut er auch nur alle 15 Minuten

Ich sehe in dem Teil mittlerweile keinen Sinn mehr

Noch dazu sollte man auch noch erwähnen, dass die App meiner Meinung nach alles andere als intuitiv ist und um auf die Handbücher zurückzugreifen, wird man weitergeleitet (wenn man den Link findet) auf die Homepage, die leider nur englisch kann und dass es bei mir zu lange her

Also für mich persönlich ist das komplett Müll

Positiv zu erwähnen aber doch verwunderlich, dass der Entwickler nicht noch Profit schlagen will und ein in App Kaufmodell daraus macht


Was noch richtig nervig ist,seit der ersten Sekunde ist der riesige Button zum teilen auf Social Media …
