APP真正爛，所以不可能有意願訂閱去了解其他資訊 ### 3/5 — 連線失敗 *2025-02-10, version 3.1.0* 更新過後App一打開就會顯示連線失敗，整個軟體都不能使用，再麻煩儘速修正～～ 另外app更新完後戒指前一天的睡眠記錄都消失了😮‍💨 還有最近戒指都偵測不到跑步的時長，常常顯示無資料😭 ### 2/5 — 怎麼註冊？ *2022-05-02, version 1.9.3* 一打開app就跳出就出現叫我註冊或是舊帳號登入，可是找不到地方可以註冊？是不是註冊需要你們提供連結才可以？要付費的意思？ ### 4/5 — высокий пульс *2020-07-10* Пульс выше 100 не отображается в sleep record. ### 5/5 — Sleep note and suggestion is helpful *2020-02-03* The app list some common and suitable solutions for sleep apnea improvement in recommendation page. The solutions are also designed as options in the sleep note to help user choose solution, take action, and observe effects. I like this design. ### 5/5 — Remote care feature is great *2020-02-03* App design is professional for sleep apnea care. I especially like the feature for remote checking my parents’ results on my phone. ### 5/5 — 戴著睡稍不舒服但很有幫助 *2020-02-02, version 1.8.0* 血氧機戴整晚稍有壓迫感偶爾會脫落，但App使用方便分析專業，對了解自己睡眠缺氧狀況很有幫助，整體C/P值OK ### 5/5 — 專業好用 *2020-02-01, version 1.8.0* 一直在找可以分析睡眠而且有醫療器材認證的血氧機, 找來找去符合需求的價格都要幾萬塊, 最近醫生推薦這個產品 用起來蠻專業而且好用 ### 5/5 — Useful Sleep Apnea Solution *2020-01-30* I had mild sleep apnea but my doctor didn’t strongly recommend me to wear a CPAP. I got many possible solutions by google search; however, I didn’t know if the solutions work. This app combined with SpO2 meter did help me evaluate which solution work for me. ### 5/5 — 能瞭解自己的睡眠狀況 *2020-01-30, version 1.8.0* 簡單易懂，量測完，還有分析，讓我了解自己的睡眠品質 ### 5/5 — Great tool to monitor Sleep Apnea *2020-01-30* I have snoring problem but didn’t try to solve it.

There is useful suggestion and sleep note in the app to help me try and find suitable solutions for me. ## Most critical reviews (10 lowest-rated) ### 1/5 — APP真的很瞎 *2025-08-08, version 3.2.6* ㄧ直連不到 超難用 ### 1/5 — 連線問題 *2025-02-09, version 3.1.0* 近期在白天時常顯示連線失敗，同步超慢，使用上很不方便。 ### 1/5 — Email帳號 *2021-06-03, version 1.8.15* 收到兩筆從日本飯店下單和樂天購物的日文email通知 ### 1/5 — 騙人的，還是要搭配血氧計。 *2021-05-30, version 1.8.15* 不要下載。 ### 1/5 — 無法配對 *2021-05-27, version 1.8.15* 藍芽無法配對 ### 1/5 — Worst design in connectivity *2020-08-03* No Proper information .never shows search and connect Bluetooth option. Time waste **Developer response:** Hello. When the user register and start use the iFORA O2 app first time, the app will show guidance how to pair and connect bluetooth and jump to bluetooth pairing page directly. We are not sure your meaning of no proper information. If you still have bluetooth problem, we are happy to help you resolve it. You could contact the service email in the app ### 1/5 — Domain problem still active *2020-04-22* Upon trying to set up account (required to use app) it says iCloud.com is not a valid domain. Disappointed. Otherwise looked like a good app. **Developer response:** Hi There were hundreds of users used icloud.com to register and use iFORA O2 app successfully in the past few months. We think there might be other issues when you typed register email. One of the common issue is user accidentally type "icloud.con" rather than "icloud.com". If you are still interested in iFORA O2 and having problems for registration, you could contact ifora_o2@foracare.com, we will be more than happy to help you resolve the issues. ### 1/5 — Hassle *2020-03-14* Must register an email to use the app. **Developer response:** Hi Because the pdf format sleep analysis report will be email to the user's registered email account, we need to have validated email address to guarantee the user could enjoy full function of iFORA O2 ### 1/5 — Can’t open *2019-12-06* I read the first review and still wanted to give it a try. You have to register to sign in but it will not accept my email domain (@me.com or @att.net) so you can’t open it or use it. They need to fix the problem!!! **Developer response:** Thank you for the valuable feedback. The email domain issue is fixed. Please let us know if these is still problem. ### 1/5 — Couldn’t even open app *2019-12-05* App makes you register with your email in order to use app. But “certification email” isn’t sent so you can activate app, my correct email is registered with both iTunes/apps and app creator, email not in spam, anywhere else etc despite multiple attempts following prompts **Developer response:** We are very sorry for the inconvenience. We tried several solutions to solve certification email issue. If there is still problem, you could contact the service email "ifora_o2@foracare.com" listed in the app. We will be more than happy to help you resolve the issue. ## Most praised reviews (10 highest-rated) ### 5/5 — 開始APP時YouTube會停止 *2026-01-21, version 3.3.2* 你好 收聽YouTube時開啟iFORA O2，YOUTUBE會自動停止播放，請問如何改善？ ### 5/5 — 版本更新後出現要email 認證 如何解決 *2024-01-28, version 3.0.0* 2023.3.7就認證了 ### 5/5 — Extra bonus for oximeter *2020-08-19, version 1.8.12* Bought the app bundled oximeter for Covid-19 recommended by NY magazine. Although the meter+app bundle price is higher than typical pulse oximeter, the sleep & hrv features in the app didn’t make me regret ### 5/5 — Useful for Sleep apnea tracking *2020-08-19* I found this app by recommendation in New York Magazine. I Originally only wanted to buy a oximeter for COVID-19, and surprised that app+oximeter could also test and monitor sleep apnea. Worthy! ### 5/5 — 請問有支持那些型號的血氧家？ *2020-06-19, version 1.8.8* 請問有支持那些型號的血氧家？ ### 5/5 — 協助找到適合的改善方式 *2020-02-09, version 1.8.1* APP依據缺氧狀況提供常見的睡眠呼吸中止改善建議，睡眠筆記整理了常見的改善方式讓自己選擇嘗試。藉由缺氧指標ODI和筆記，終於知道那麼多改善方式哪種對自己比較有用！ ### 5/5 — Pricy but worthy *2020-02-05* Oximeter and app bundle is pricy. App analysis report is professional and match with the result that I did at the clinic. I use report and sleep note to test and improve sleep apnea for my whole family. It is worth it. **Developer response:** Thank you for the feedback. FORA oximeter appearance looks like typical finger type oximeters; however, FORA oximeter+app solution does provide much powerful features compared with those meters. That’s why our product price is higher than typical meters. Our product is at similar price as the SpO2 solutions focusing on sleep analysis. FORA oximeter has FDA approval, but some of the similar products don’t. Besides, other than sleep analysis feature, our solution also support HRV and HRV biofeedback features, which are extra bonus compared with other sleep solutions. Some similar products with only HRV and HRV biofeedback features are not cheap. We have been doing our best to make our product worthy. Any comment and suggestion will be appreciated. ### 5/5 — App good, meter uncomfortable but accurate *2020-02-05* I tried other Apps with bundled ring or finger type Spo2 meters to monitor my sleep apnea. They were not so easy to use or not very accurate compared with the results of sleep center. A physician recommended this solution to me. Wearing the oximeter bundled with app is not as comfortable as ring oximeter, but the results is more similar with the sleep center. The app is professional and easy to us. I like it. **Developer response:** Thank you for sharing experience. Based on the study, the SpO2 reading measured from finger tip with transmission oximetry technology (light transmitter and receiver on the opposite side) has better accuracy. Because accuracy is most important for our product, the wearing comfort is a little sacrificed. We are sorry for that and will keep improving the comfort by wearing accessory design. ### 5/5 — 治療追蹤好用 *2020-02-04, version 1.8.0* 台中醫院的醫生介紹，戴著血氧機睡覺花了幾天才適應，App的缺氧指數搭配睡眠筆記做睡眠呼吸中止治療追蹤好用。 ### 5/5 — A Little Uncomfortable but helpful *2020-02-03* Wearing the meter during sleep is a little uncomfortable at the beginning. It took me 3 days to get used it. App is professional and helpful for sleep apnea problems. **Developer response:** Thank you for the feedback. We think doing sleep test with oximeter at home is more comfortable and convenient than doing test at sleep center. However, we understand our oximeter is not as comfortable as ring or wristband type oximeter. That’s a choice and tradeoff between accuracy and comfort. We are sorry for sacrificing comfort to get better accuracy. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
