But now, I’m unable to get anyone from customer service to assist me and the app just says that I have no internet connection and to try again later. That’s been happening now for two days. I most definitely have internet connection on my phone because I have no trouble with any other apps. If I could get someone to assist me, then my opinion would change to at least four stars, but this has caused a huge problem. For an item that’s $120+ this never should be an issue. ### 2/5 — Won’t let me log back in *2022-07-18* Please fix this. I have had all my data here for months tracking my period. Now it says that there’s no network connection when trying to restore my old account. When I 100% have internet connection. ### 2/5 — Worked for 2 days *2021-12-26* Will not record temperature when I open app in the morning. Only connects and that’s all. ### 2/5 — Horrible app *2021-02-09* How do you read your iFertracker if the app doesn’t even work right? Cannot even add in last period date. It just keeps asking for data no matter what you submit ### 2/5 — 经常连不上 *2019-10-08* 发邮件给开发人员也不回 ### 3/5 — 太KY了 *2019-05-16* 提醒一个备孕的人你快来大姨妈了，心情一下超级down ### 3/5 — 产品优秀，系统后续开发不足。 *2017-07-18* 我目前已经使用三个多月了，这个测体温，我觉得基本还是很准的，按照它的这个说明和阐述是仅低于排卵试纸的准确度的存在，但排卵试纸没这个方便，所以我买了这个。使用感还可以，毕竟简单，就是腋下被粘得偶尔会不舒服。但是，它这个只有每次上传体温的时候才会有各种关于怀孕的知识，其他地方我并没有找到，而且智能分析感觉不足够先进，总之500多我感觉如果仅仅只有目前这些功能真的感觉很鸡肋。而且每天戴着你就会更加关注你的怀孕情况，莫名更加焦躁。 建议多找一些备孕期的高知女性做产品测试及功能建议，因为总得来说产品本身还是方便优秀的，系统开发更合理人性化我觉得会更受欢迎。 ### 3/5 — Doesn't sync to Apple health anymore *2016-10-09* Would add another star if this is fixed. ### 4/5 — App bugs fixed after this update *2016-09-07* The product works well. It even alerts you when a temperature spike is suggestive of ovulation. The display of data is user friendly and easy to interpret ### 1/5 — 更新後用不到 *2016-08-26, version 3.0.0* 好差呀⋯⋯ ### 1/5 — Apps不停的閃退 *2016-08-26, version 3.0.0* Apps不停的閃退,完全進不了apps ### 1/5 — 更新後不停彈app *2016-08-24, version 3.0.0* 今天更新後，一進入app後，不需要5秒，app即刻彈出，急需修正 ### 2/5 — 閃退問題 *2016-08-24, version 3.0.0* 剛剛更新了，閃退問題根本開不了，今天不能輸入資料了 ### 1/5 — 差！ *2016-08-24, version 3.0.0* 更新後一直彈app! ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken App *2023-06-13* Worked great for about 1 year then would not connect to my iFertracker device. Tried re-downloading didn’t help. It has now logged me out and constantly says no internet connection even though everything else on my phone works. ### 1/5 — Read the reviews. Don’t purchase. *2022-05-31* I should have read the reviews entirely before making a purchase. Find another BBT tracker because this one isn’t worth it. 1. A 12 character password is a joke. There should be a higher maximum for password creation. You cannot make a meaningful pass phrase with only 12 characters. 2. I have been using this product for 4 days and already have a low battery notification. If you have to buy a battery weekly it isn’t worth it. 3. This app is NOT good for irregular periods despite anything it might claim. I was 4 months postpartum when I bought this and didn’t have my period yet and it wouldn’t let me use the app at all without entering a “last period” date. Was a women even consulted when this device and app were created? ### 1/5 — Account Issue *2021-01-07* Can’t proceed with app usage without creating an account; however, the app won’t allow me to enter a password to create an account. Rendering a 130 dollar piece of technology useless. Your developers should be ashamed. Account creation, or at least the ability to circumvent account creation, is incredibly basic. ### 1/5 — Doesn’t work *2020-11-19* The app opens but I’m not able to add the date for my cycle. It doesn’t matter what date you put in. ### 1/5 — Nice but not Working Every-time it was get hang *2020-10-16* Phone get hang ### 1/5 — Don’t bother buying *2020-06-27* Awful for people with pcos, don’t waste your money, app is so basic compared to other apps, I had a partial refund as it wasn’t suitable for pcos and the then the device stopped working conveniently. Think I would rather use my money towards actually treatment than this device. If you live in the UK don’t order as you get slapped with custom charges every time. £40 the first time for device and £27 the next just for patches so really not Worth buying! I’ve never had custom Charges before on anything but this company it’s every time. Please listen to the reviews of how crap it is. The website reviews are a load of bull! Don’t even think they are real people, I left a review didn’t go on there. Save your money guys! Didn’t even deserve 1* ### 1/5 — Not great *2020-05-06* When setting up it asked me for when my last period started which was in January but it did not let me go that far back to log it. ### 1/5 — One big issue. *2019-04-08* As far as bbt temp tracking, the iFertracker itself is great. I got it and this app because we have struggled to conceive and keep a pregnancy. My last miscarriage has messed up my cycles, and on top of that I have PCOS. I understood iFertracker was designed for women with irregular periods, but this app literally won’t let me do anything unless I log my period, which was so long ago that it’s calendar won’t let me. I’m disappointed and frustrated and feel like I wasted my money. ### 1/5 — 不能升级 都是老版本 还是最贵的时候买的 *2018-01-11* 不能升级 都是老版本 还是最贵的时候买的 ### 1/5 — New version-Update *2016-08-28* This new version is abhorrent. The application closes out automatically within seconds of opening. Also, it refuses to pull my data for 'unknown' reasons. When they switched to the new versions, I lost 4 days of data in my chart & of course you cannot amend the temperature data points. The old version I utilized just a mere 3 days ago, was great. It read my data. It would stay open longer than 3.0 seconds. In short, the old one worked. This new version is a piece. After spending so much money on the tracker, it's upsetting to have the new application version just not work. **UPDATE** I see about 3 hours ago the app was updated again. And, much to my dismay still does not work -- continuously closes automatically upon opening. Im excited for the new version if it would just work. 😒 ## Most praised reviews (10 highest-rated) ### 5/5 — Love it!!! Needs bug fixes desperately!!!! *2022-04-06* I love this device and app how ever they should allow for editing of your complete cycle considering FAM folk want to keep record of LH testing and log proper ovulation. With this being said I know I ovulated later last month and I can’t seem to edit its misinformation. March cd 1 February 25 Ovulation cd 19 march 14 Next cd 1 was march 28 That would mean last cycle it was a 32 day cycle not 28 which is what you app seems to think everyone is on for cycles not every woman has a 28 day cycle and no cycle is the same amount of days so please fix this or I will forced to send back all of your products just saying it’s sad when Premom has you beat with a bbt and lh chart to track both you should really consider doing the same ### 5/5 — 特别准确的预测大姨妈 *2017-08-30* 监测基础体温实在太方便和准确啦！早上醒来发现体温降低，中午大姨妈就来了。还好有这个精确提醒我大姨妈！ ### 5/5 — 怎么没有怀孕的按钮呢 *2016-04-03* 怀孕后也要检测基础体温的，所以最好新增怀孕以后的选项 ### 5/5 — 感觉不错 *2016-01-30* 5天后 就发现怀上了~~虽然基本不是孕律的作用，但使用效果还是很好的.体温测试很精准.现在还在坚持用.看来还是个吉星高照的福物啊~~ ### 5/5 — 很喜欢。 *2016-01-30* 使用过程中还是挺满意的，也没有出现其他人说的很费电的情况，省去了每天早上测体温的麻烦，整体很满意，希望早日能实现愿望！ ### 5/5 — 挺好用的 *2016-01-30* 很适合我这种早起忘事的人，每次看完手机上完厕所才想起要测体温已经来不及了。另外，微信客服非常好，答疑非常专业热心。 ### 5/5 — 不用操心 *2016-01-30* 非常智能的设备，免去了手工记录和测量不准的烦恼，操作简单方便，希望能增加导入之前体温数据的功能。 ### 5/5 — 感慨万千 *2016-01-30* 产品很小巧，试用了两天，睡觉完全不影响，感觉非常方便，早上醒来直接跟IPAD连接，不要跟之前一样用温度计测了，很棒，希望早日好孕 ### 5/5 — 很放心 *2016-01-30* 用了一段时间了，佩戴和上传数据都很方便，提醒的功能和记录的功能也很实用，就是早晨摘掉的时候拉扯到皮肤会有点不舒服。 ### 5/5 — 可以自己掌控 *2016-01-30* 挺不错的备孕产品，预测的月经以及排卵都好准的 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
