### 3/5 — ゆゆゆゆ

*2026-06-11*

熱っぽい時に体温計がなかったから助かりました‼️😼指だから精度が心配だけどとりあえず測れたのでＯＫ👊🏻🌡

### 1/5 — 課金したのに…

*2025-07-01*

Apple Watchで自動で体温検知してくれるというので、課金した8000円も！
なのに設定関係確認しても、そういう設定にならないし、返金して欲しいです。
途中でアプリが強制終了したりウィジェットも消えていたり。バグありすぎだと思います。

### 1/5 — Mai andata

*2025-06-04, version 1.1.9*

Non sono mai riuscito a provare, ma zero eh, neanche un volta, la febbre nonostante abbia pagato i 5,99

### 3/5 — 私死んでんの？

*2025-05-04*

普通な体温も出ますが私が使った時は死んでいました35.2なんてありえないですもう少し修正してください(´･_･`)

### 1/5 — Scam

*2025-04-09*

If you don’t have Apple Watch it is useless and can’t cancel

### 1/5 — アプリが速攻落ちる

*2025-04-01*

何やろうとしてもアプリ落ちてホーム画面に戻される 体温計で測って39.5℃の時、このアプリ使ったら38.3って言われたからあんま信用してない
とにかくアプリ開いて10秒くらいで落ちるのどうにかして

### 1/5 — No trial no buy

*2025-03-09*

I want your app to work.  But there are so many that don’t.  Paying $5.99 for a week or $29.99 for the year to try. If there are many like me, you might want to consider a 7 day trial if you think your app does the job well.  I would be a fan if I can see, even if was a 3 day trial. We would not be asking for much to spend that money before knowing it works is blind faith and I ain’t got it.  Best wishes for future sales.

### 1/5 — 体温が違い過ぎる

*2025-02-21*

急に体調が悪くなったんですが、引っ越したばかりで体温計を買っていなかったのでこちらのアプリを利用しました。
結果は36.9度や37.2度ばかり……そんなはずは無いと念の為近くのクリニックに行きましたが体温は38.9度でコロナでした。
スマホで体温なんか測れるわけがないとあまり期待していませんでしたがここまで違いがあると……大人しく体温計を買った方がいいです。

### 1/5 — 体温計で測ったのと体温が違いすぎます。

*2025-01-21*

実際に本物の体温計で測った体温と違いすぎたのでアンインストールさせていただきました。

**Developer response:** 温度測定の差異を説明していただけますか？
問題をよりよく理解したいので、教えていただけると助かります。

### 1/5 — Just a grabber

*2025-01-09*

It does provide heart rate which other apps can do as-well but it wants to track all of your health data. While you can still use it when you decline. I still just see the purpose of it in grabbing data. The thermometer data is rather inaccurate and i just wanted to know if it is possible to get anything close to an accurate reading which it does not provide. Therefore the app is useless in the case you actually download it for.

### 1/5 — 骗钱把戏

*2026-08-13*

扣了钱，在iPad上说没闪光灯不能用，下到手机上，还让交钱。

### 1/5 — Mauvaise app

*2026-01-21*

Votre app est nulle. D’abord vous ne prévenez pas qu’elle sera payante et après on ne peut plus la supprimer. Personnellement je trouve ça minable !!!!

### 1/5 — Achat direct

*2026-01-17*

Aucune période d’essais pour voir si l’application est fiable et au bout de3 jours t’oblige à acheter pour lire les résultats

### 1/5 — These blood sucking,,,

*2026-01-15*

OK, so just allow people to understand the situation that I’m in I am out of town working I’m 10 hours away from my house. The place that I’m staying does not have a thermometer and I am sick as a dog. I downloaded this because it was like the first thing that pops up whenever you look for thermometers and then it’s got a 4.6 rating Only problem is these blood suckers wanna charge you for the app? I’m now currently going to the hospital. I don’t know what my current temperature is but I’m guessing it’s pretty high. So instead of having an option where you could try it free for a day and maybe I don’t know do what other lucrative app and p an advertisement put an ad advertisement right after you use the free app how many medical supply places providers doctors would not kill for that prime piece of advertising real estate. I can just imagine if I was in a different country and the thermometer was a difference between life and death. Oh, but I can’t use it because I don’t have I don’t have 599 because I’m in a Third World effing country so way to go guys way to push yourself up to the top of the download list not only in app but also on Google I hope that 599 is a difference between somebody living and dying, and I hope that hangs on your soul for the rest of your life

### 1/5 — What?

*2026-01-08*

Tried this in a pinch, was a pain to just get a simple temp read, and no clue if it was even accurate. Took my $30 though, so there is a high fever. Canceled /removed immediately.

### 1/5 — サクラを疑う評価

*2025-12-27*

何度やってもまともに計れません。
腋で挟む体温計では38.0、このアプリでは35.5とか36.0とか。
手元に体温計が無かったために使用しましたが後悔しています。400円と高くない金額ですが返して欲しいレベルです。

### 1/5 — 不怎么样

*2025-12-03*

钱能退吗？

### 1/5 — 課金アプリ

*2025-10-26*

アプリ内課金ではなく、課金しないと使用できない、、

### 1/5 — Rip Off

*2025-07-16*

Once you download this app and open it, you are directed
to other body data (blood pressure, oxygen levels, etc) and EACH one costs 29.95.  Adds up to an outrageous amount of money for health apps!

### 1/5 — Fake

*2025-07-07*

Absolutely no sense! Waste of time.

### 5/5 — Helpful

*2026-05-18*

Helpful handy & easy to use.

### 5/5 — Works well and accurate

*2026-01-22*

Straight forward measurement and accurate results that match thermometer results. 

I’ve taken multiple readings and also compared side by side to thermometer, max variation was within half a degree. 

No longer absolutely need the thermometer and can take a reading on the go with this. Fine work. Tech has gotten really good.

### 5/5 — イェイ

### 5/5 — I love it

*2025-12-14*

So I was sick and it works

### 5/5 — 詐欺アプリ

*2025-09-29*

無料アプリということでインストール。初期設定で誘導され課金させられる。悪質な詐欺アプリ。全く課金の意思も無いのに返金にも応じない。全て記録はしているが、都合の悪いレビューや無料の表記も削除している。

### 5/5 — Simple et efficace

*2025-08-03*

Très commode d’utilisation sur iPhone 16. Précis car contrôlé avec un thermomètre à mercure.

### 5/5 — Cool

*2025-05-01*

Es hat gut funktioniert

### 5/5 — Very handy

*2025-04-02*

Since i don’t have thermometer at home, this app helps me to monitor my body temperature as i am tracking my temperature.

### 5/5 — Never lose the thermometer again

*2025-01-16*

I love this app!  Have to take my temperature regularly due to a health issue.  I never leave home without my phone, so I always have my thermometer with me.  I have compared the readings to a forehead thermometer and they are very close.  
I had an issue with the app and reached out to support. They were very prompt in responding and helped me resolve my issue.
