The time setting seems to be fixed and varies quite a bit between individual sensors. It would nice to be able to reset it to correct synchronicity. Today the App seems to have stopped working and is giving garbage readouts. I have deleted it and reinstalled it but it still seems to no longer work. The App no longer shows the pie chart only the bar chart. This is a reduction in usefulness of the App. This is with iPhone 16. ### 4/5 — Sehr gut für den fünften Stern wären Unterstützung von Kurzbefehlen super 👍 *2025-07-21* App macht was sie soll. Nutze diese zusammen mit einem BT Thermometer um die Temperaturim Kofferraum für meine Hunde zu ermitteln. Das funktioniert super nur leider muss ich dafür während der Fahrt das iPhone in die Hand nehmen. Was großartig wäre wenn ich per Kurzbefehle die Aktuelle Temperatur über Siri angesagt bekomme oder eine Warnung wenn eine Temperatur überschritten wird und ich mit CarPlay verbunden bin. ### 3/5 — Sensor friert ein *2025-05-02* Leider hat sich am zweiten Tag der Nutzung schon einer der drei genutzten Sensoren nicht mehr gemeldet und das Bild blieb eingefroren. Der Sensor war nur noch grau hinterlegt und nicht wie bei den aktuellen und angebundenen Sensoren grün. Auch ein Refresh hat nicht geholfen, dass aktuelle Daten angezeigt wurden. Ich musste den Sensor komplett aus der App löschen und neu installieren, so dass ich wieder aktuelle Daten bekomme. Bin gespannt, wie lange diesmal die Verbindung bestehen bleibt. ### 3/5 — Application *2025-04-30* Peut mieux faire Il ne semble pas possible de modifier la fréquence des mesures, 10 mn. Je n’ai pas trouvé la possibilité de remettre à zéro après importation des données ### 2/5 — Sensor Blues *2024-09-20, version 3.5.1* It senses fine but won’t log the data. -Disappointing! It’s my 2nd sensor to fail - there won’t be a third ### 2/5 — スマホから室温が見れるのは良い *2024-08-27* アプリを開かないと設定した温度の通知が来ない。 ### 3/5 — Current status *2024-08-01, version 3.5.1* I have used these devices for several years and generally they work OK. The time setting seems to be fixed and varies quite a bit between individual sensors. It would nice to be able to reset it to correct synchronicity. Today the App seems to have stopped working and is giving garbage readouts. I have deleted it and reinstalled it but it still seems to no longer work. ### 2/5 — Sensor zeigt nur noch Echtzeit Daten an kein Diagramm mehr dargestellt *2024-06-08* Anfangs war die App wirklich gut. Seitdem letzten Update dauert es eine Ewigkeit bis es Synchronisiert ist. Leider gibt es keinen Verlauf mehr und beim Diagramm Status Logger ist zwar ein Grüner Punkt aber es gibt keine Daten mehr. Er fängt immer wieder einen neuen Log an und man sieht nur die Daten von gerade eben. Somit unbrauchbar geworden —> landet auf dem Müll und wird durch ein gleichwertiges Modell von Inkbird ersetzt. ### 2/5 — Eingeschränkte Funktion *2024-05-13* Der Hersteller schreibt bug fix, aber nach dem Update dauert ein Sync Ewigkeiten, auch wenn man direkt am Sensor steht und die Akku und Netzstärke bei fast 100% liegen ist eine Synchronisation fast unmöglich. Ich wollte mir weitere Sensoren kaufen weil ich das Hard und Softwaredesign sehr gelungen und durchdacht finde. Bei der Dauer muss ich mit jedoch was anderes suchen, ich kann nicht 15-20 Minuten pro Sensor warten… ### 2/5 — All but ruined with the recent updates *2024-03-24, version 3.4.9* It still tells the current temp and humidity but the logging feature is all but useless now for me. I don't constantly sync, and only want to see the last couple days or so, so if it's been a week or longer, it takes an absurd amount of time for it to sync. I don't need that data, but why should it take so long to sync anyway? Timestamp, temp and humidity. Even the full 100 days with worth at a record every ten minutes, even with 100 bytes for each record, that's less than a couple MBs. This should take only a few seconds on bluetooth. ### 2/5 — 湿度を変更できない。 *2024-02-10* 自宅の温度計に合わせて温度湿度を調整したいが、温度は調整できるが湿度はなぜか数値が9.99になってプラスできない。 後ウィジェットに対応してほしい。 ### 4/5 — Russian *2024-01-21* Please add Russian to languages. Thanks. ### 3/5 — アップデート不具合 *2023-12-06* 追記： アプリの再インストールとセンサー側のリセットを実施して、今のところ正常です。 まだ2日なので、また変化があったらレビューします。 アプリがまたアップデートされていますが、しばらく様子見ます。 初期化で正常に動作しているようなので、評価は3に上げます。 使い始めて一週間間、ちゃんと機能していたのですが、ver.3.4.1にアップデートしてからまともにログがちゃんと表示されなくなりました。 勝手にログファイルが切り替えられ、グラフもおかしい。 センサーとの同期は実行されているようですが、ちゃんと読み取れているのか分かりません。 センサー側はちゃんと記録していると信じてアプリのアップデートを待ちます。 100日以内に正常になるといいのですが。 今の評価は１ですが、先日までは良かったので評価２にしときます。 **Developer response:** こんにちは、V3.4.4をお試しください。 ### 2/5 — Issue with last update *2023-12-04, version 3.4.2* Worked perfectly before the most recent update but now 2 of my 4 sensors are no longer showing me the humidity log ### 2/5 — Notifications do not work *2023-01-31, version 2.1.8* As other reviews correctly state, you won’t receive any notification on your phone unless you open the app, so it’s pretty useless on that sense. The measurements seem to be correct though. ### 3/5 — Ok but *2023-01-24, version 2.1.8* The ipad version doesn’t display mold risk. My android version does for the same hygrometers. Wish they were ifttt or smart life compatible. That’s what I get. I guess for buy cheap devices. ### 1/5 — Latest update *2023-01-18, version 2.1.8* The latest up date on the time interval for displaying data does not work correctly (keeps going back to current day) and if it did will be a retrograde update. Now looking for an alternative supplier. ## Most critical reviews (10 lowest-rated) ### 1/5 — Can not calibrate *2026-03-06, version 3.6.1* Calibration does not work ### 1/5 — App crashing *2024-06-26, version 3.5.0* Crashes when trying to view logged data ### 1/5 — App has stopped recording *2023-12-11, version 3.4.4* I don’t know what happened but the app is thoroughly broken It used to work well, although it lost its history when the battery in the thermometer was changed Then it stopped displaying the humidity graph Now there’s a button to show the humidity graph but neither temperature or humidity is recorded Please fix or at least revert to a version that worked ### 1/5 — 湿度のグラフが見えなくなった *2023-12-09* 以前はグラフの所で温度・湿度の切り替えが出来るようになっていたが、今は温度・湿度を選べなくなっており、温度のグラフが表示されている。 version 3.4.4 センサーを削除して、再登録したらグラフに温度・湿度が選べるようになりました。 **Developer response:** こんにちは、フィードバックをありがとうございます、あなたによって引き起こされたバグを実行しているいくつかのiPhoneのアプリについて、私たちはこれら2つの問題をチェックして追跡するために最善を尽くしています。 ### 1/5 — Humidity button has disappeared *2023-12-04, version 3.4.2* Since latest update (currently on 3.4.3) the option to select between temp and humidity has disappeared. I cannot see a chart for humidity. iPhone 12. ### 1/5 — It won’t stop beeping *2023-12-03, version 3.4.2* After the latest update my two sensors won’t stop beeping and there’s no way to turn it off. I just took the battery out. ### 1/5 — Major bug in 3.4.1 *2023-12-02, version 3.4.1* My iPhone 12 updated the app to 3.41 and humidity history / detail has disappeared! All I can see is temperature . Are you releasing a fix ?? The product is pretty useless to me now if I can’t see humidity history.. ### 1/5 — データ回収が全部はできない *2023-09-03* データを転送していてもしていなくても、定期的にリセットされるので、リセット寸前のデータは回収のしようがない。 リセットが人為的にできないとダメですね。この手のデバイスは、制御アプリが軒並ハズレです。本件含め。 ### 1/5 — Wont work for long, then junk *2023-04-01, version 2.1.8* My thermometer worked until the battery ran out, when replaced absolutely no way of re-pairing with the app. Things like this are great until the app doesn’t work and then instantly become junk. Sooner or later your funky plastic thermometer/hydrometer thing will suddenly and unexpectedly become completely useless, you’ll have to throw it away and it will spend the next 200 years slowly disintegrating in a landfill site somewhere, or worse break up into tiny pieces sooner, flush into a river, disperse in the sea, the bits eaten up by fish made into fish fingers you or your grandkids feed to their children. The vast majority of the time all the things this app connects to will be spent as junk, a brief few months they’ll actually work. Don’t do it. Don’t buy in to this evil rubbish. ### 1/5 — Terrible garbage *2023-03-05, version 2.1.8* I have a sensor blue hygrometer in a chamber. The thing will not report the right humidity. I have three other sensors all the same and this is WAY off. It is so off that it seemed that it couldn’t not possibly be right. I need a hygrometer that works. Only but this if you want an expensive piece of garbage to tell you completely different humidity levels. You might as well buy a 1 dollar piece of plastic and have it report the data to you. Just more useless garbage that I bought that doesn’t work. ## Most praised reviews (10 highest-rated) ### 5/5 — No problems with hygrometer *2025-07-20, version 3.6.1* Have been running these for a few years with no problems. Had to properly calibrate them as a few degrees off for both temp and humidity but the software has an inbuilt tool for that . Also you have set up a new log when the battery dies and the device resets but again not difficult. The developer of the App is good and responsive - I found a bug and he fixed it . Can’t ask for mor than that 😀. I read another review for the product that was bad but the person clearly didn’t understand how to reset the device after battery change so more of a user issue.. ### 5/5 — 校正画面 *2024-06-08* バージョンアップ後校正入力文字が白で見にくいです。 改善お願いいたします。 ### 5/5 — Fast perfekt *2023-12-30* Gute App, easy Einrichtung. Das einzige was noch fehlt ist ein Widget :) ### 5/5 — Sehr zufrieden! *2022-10-27* Da gab es wohl ein kleines Update…. Ich war vorher schon zufrieden, aber jetzt perfekt für mich. Endlich muss ich die Temperatur unten nicht mehr klein ziehen, um zu sehen was in den letzten 5Stunden für eine Temperatur war. Es ist seit heute genau so voreingestellt, wie ich es immer einstelle, bzw. an dem „Balken“ ändere. Werde mir definitiv noch 2 oder 3 Sensoren gönnen. Bin gespannt auf die Reichweite der anderen, in den oberen Räumen. Den, den ich jetzt habe, steht etwa 3m von mir entfernt, wenn ich auf der Couch sitze. Batterie hält auch schon ewig! Also ich kann den Sensor, sowie die App nur empfehlen! Habe absolut nichts zum aussetzen. Weiter so!👍🏼 ### 5/5 — Brifit Bluetooth Thermometer *2022-10-20* Ich verstehe viele der schlechten Bewertungen nicht, wahrscheinlich wurde die App seitdem überarbeitet, denn bisher bin ich sehr zufrieden (2Monate), die App ist übersichtlich, intuitiv und die Werte scheinen auch zu stimmen! Alles in allem, kann ich das Produkt samt App weiterempfehlen! ### 5/5 — Easy to connect *2022-10-16, version 2.0.2* Easy to connect to my iphone, but one question can i also add the unit to my ipad also? ### 5/5 — Absolutely remarkable but one enhancement could make this stellar!! *2022-01-28, version 1.5.36* The sensors are absolutely amazing for the money and accuracy - but what would be epic is if the app could include Absolute Humidity as well as relative humidity (even if you needed to approximate for air pressure!). This would be such a cool and useful enhancement that would put this head and shoulders against any competitor product! ### 5/5 — Great product fully functional and excellent price! *2021-11-12, version 1.5.30* I’m a fully certified electrical/electronic/ mechanical engineer so this absolute truthful evaluation! 1st, the device and the software applications as specified is fully functional. Meets all normal requirements for measuring and data logging of the specified temperature and humidity range (on batter power) as specified by the mfg! 2nd(A), the operational learning curve will require a little more dedicated time in order to FULLY understand and operate the device. (As evident in the previous reviews, this was not done properly by the users)! 2nd(B), however documentation as well as application layout screen need to -clearly- identify “button” areas that will activate recall of data logged information and historical capture features, both options are fully functional that is not evident on the application display screen. 3rd, the device is NOT electrical radiation protected! Mounting the device in proximity to high frequency electrical signals will interrupt Bluetooth communication with the device - however the device will continue to data log T and H information correctly and must be removed to down load data. Area's such as in computer cabinets, electrical panels, and near power out let’s, should be prohibited. 4th, battery operation (drain) excellent (still in operational testing) plus 4 months and counting. 5th, out the box calibration is sufficient and applicable! 6th Bluetooth range is at spec. 7th, durable in design and fabrication. Recommendations: -Identify button areas on application to display recorded (sync) data. -add optional holder enclosure other than magnets. Example rubber housing with attachment holes. Comments, initial purchases were two (2) units to test and verify. Now purchasing additional four (4) units to complete project. Status:POSITIVE RECOMMENDATIONS ### 5/5 — Tolle Geräte und App. Bin sehr zufrieden. *2021-10-02* Bin sehr positiv überrascht. Die Sensoren und die zugehörige App sind hervorragend. Die Paarung der Geräte mit dem iPhone oder iPad ist selbsterklärend und geht wie der Blitz. Für mich erstaunlich ist die Reichweite. Vom Wohnzimmer durch eine Betondecke in den Kühlkeller erweist sich nicht als Problem. Auch der zweite Sensor ist im Keller untergebracht, in einem Weinkühlschrank. Auch hier null Probleme. Mal abwarten, wie sich die Sensoren auf Dauer verhalten. Bislang kann ich den Kauf nur empfehlen, zumal der Preis mehr als angemessen ist. ### 5/5 — Greenhouse temp *2021-03-16, version 1.5.25* Got this for my greenhouse easy to setup and works very well Bluetooth in my bedroom now about 30m away through a wall and window and glass in greenhouse and getting live readings for £10 what a very good temp gauge and app had it only 1 day and it’s magic I have 200 USA Sarracenia plants carnivores plants --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
