Brilliant actually period. Unfortunately it does not connect to Apple Health app. Which is very unfortunate. It’d be helpful to have all information in the one app. ### 4/5 — Rating: 4.5/5 *2023-09-19, version 1.122* I had some initial reservations given the bugs post-update, but all seems smooth now. I’ve been using it daily to monitor my internal health metrics. Super easy to test. ### 4/5 — Great health insights app 👍🏻 *2023-09-16, version 1.122* Being able to track my internal age is intriguing. Since the recent update, I’ve noticed improved reading accuracy. UI could use a few polishes, but overall I highly recommend for anyone looking to dive deeper into their health. ### 2/5 — 身長がリセットされる *2023-08-25, version 1.115* 身長が大切と書いておきながら、身長を入力してもセンチの部分がリセットされる。まったく酷い。 ### 4/5 — 突然アプリが使えなくなった *2023-07-16, version 1.108* 再インストールしたが受け付けない ### 2/5 — Refresh the User Interface *2022-11-15, version 1.102* I concur that the app needs a major UX refresh. ### 2/5 — Needs major update *2020-11-01, version 1.97* Many of the other reviewer‘s are exactly right about what’s wrong with this app. It only works in landscape mode, the text boxes are not sized properly, and many other little things that make this version in bad need of an update. I think the products in great but the app leaves a lot to be desired. ### 2/5 — Like the device, hate the app *2020-09-30, version 1.96* This app is like somebody just threw something together to make it work. He gets the job done but it’s horrible to use. It only works in landscape mode but the app designer didn’t even take the time to appropriately size the text boxes that pop up to provide guidance on how to perform the test or interpret the results. The graphing is actually adequate in terms of the pulse waveform display. The interpretation of the internal age display is somewhat sparse in nature. But it gets the job done well enough. Overall, it would be appreciated if the designer would go back through and just sort of update things to freshen up the UI. ### 4/5 — Pro *2020-05-01, version 1.94* 英語版のproなら、SpO2も表示します ### 2/5 — 色々と… *2019-07-18, version 1.93* プロフィールの年齢は80歳までしか登録出来ません！自分は院でも活用してるので、元気な高齢者はたくさん居ます。 指を置くポイントやコツなどありますか？ 置く場所によって差があり過ぎて…どこが一番良い結果なのか分かりづらい！ 本体の価格、安い物ではありませんよ！ ### 3/5 — It’s a cool idea, but UI is terrible *2019-02-13, version 1.90* It forces landscape mode on an iPhone, and uses amateurish and non-familiar UI elements that don’t respond naturally. A more refined app UI would make this a really cool product. ### 2/5 — Horrible UI execution *2018-11-28, version 1.89* I would easily give the app a five-star but the user interface is terrible...it’s not optimized for mobile at all. The technology is cool and the results insightful, but working with and viewing the data - particularly the trending graph history - is sub-par. Great example of getting the ball to the one-yard line but not being able to get it across the goal line! ### 4/5 — バージョンアップしたらプロフィール変更ができない *2018-11-09, version 1.88* iPhoneXsMaxで使いました。 もともと5つしかプロフィールを登録できないのですが、アップデートしたらプロフィールの変更ができません。 修正しないと使えないので星1つです。 2018.11 アップデートで変更できるようになりました。星4つへ。 ## Most critical reviews (10 lowest-rated) ### 1/5 — Perhaps the worst app of all time? *2025-05-13, version 1.147* Let's start out by saying I really love the hardware and have been using it for years, but the app, OMG. It is functional in the sense that you get the readings you want to get but it looks like it was designed as part of a high school class project. The hardware is not cheap so I cannot imagine ### 1/5 — Useless *2023-10-21, version 1.129* App now just crashes so my £100 piece of hardware is now useless. Pathetic. ### 1/5 — Crashes immediately *2023-09-07, version 1.119* I have just updated the app and iOS on my iPad Pro and the app crashes immediately upon launch. ### 1/5 — New Design a Canadian Embarrassment *2023-07-17, version 1.108* The new design is an abomination to mobile app design. It is clear some newb teenager or third world outsource company re-designed this app. It’s so bad I want to chuck my iHeart in the garbage. The history tab starts with the oldest record and if you have thousands of records you can’t even get to the latest recordings. The analysis tab is totally meaningless now. If management is smart, they’ll pull this versions and go back to the previous design. I’m at total awe of how Canadian companies can’t do technology and design right. You have 9 months trapped in doors each year. What are you doing with your time?! And yet you want to charge people for this trash?? Another example of why you should never buy IoT devices that depend on software and servers. ### 1/5 — Possibly Outstanding Hardware Cripple by bad software design *2020-08-04, version 1.95* Super bad responsiveness. Horrible layout. Forced to view in landscape mode. The only good part so far was that it did not crash and I was able to see my Internal Age score. I guess the other good point was that it was able to connect to the hardware without any issues at all. Beyond that, however, this app needs a complete rewrite to even be considered something usable for iOS standards. I am actually surprised it made it through the App Store submission process in its current form. ### 1/5 — 使えない！ダメダメですね！ *2020-07-19, version 1.95* 起動して直ぐに落ちてしまいます。 使い物にならない。 トラブル対応能力にも疑問を感じます。 ### 1/5 — iPhoneSE *2020-07-08, version 1.95* 20200708突然アプリが落ちる様になった。 全く使えない、iPhoneの問題では無さそう。 サーバーがやられた？ ### 1/5 — Doesn’t work *2018-04-26, version 1.85* Where do you get the unit that will read the information? Was able to register but nothing else. Just shut down. ### 1/5 — Doesn't work with IPad Pro w/IOS 10.3.3 *2017-08-11, version 1.79* This app doesn't work with the latest Ipad Pro 10.5" running IOS 10.3.3. It installs OK. The first time it is started, it runs OK, allows you to create an account on iHeart's website, lets you create a profile, and even lets you run one test, pairing successfully witrh the iHeart device. It also uoloads the results OK to your profile on your new iHeart web account. So far so good. But, a minute later, the app crashed, and all subsequent attempts to resatart it fail. It briefly displays the title screen, then immediately crashes again. Rebooting the IPad, and uninstalling and reinstalling the app have no effect. While it has potential, this app needs more work before it is ready for prime time. ### 1/5 — Retired *2016-01-05, version 1.66* Does not provide analysis for people over 80. BAD BAD ## Most praised reviews (10 highest-rated) ### 5/5 — Nice App! *2024-07-01, version 1.140* I appreciate this app for enhancing my awareness of aspects of my well-being that my Apple Watch doesn't track. Highly recommended for fitness and wellness enthusiasts! ### 5/5 — Internal Age Improves With Exercise *2023-09-19, version 1.122* This app allows me to assess Aortic Stiffness, displayed as Internal Age, using the iHeart oximeter and a 30 second test. I notice that exercising regularly lowers my Internal Age. I especially like that I can check in on my Internal Age every few weeks and don’t need to wear anything to stay on top of a key body health metric. ### 5/5 — Great Device! *2023-09-18, version 1.122* I’ve always wondered if I was the same age on the inside, as I am on the outside. Now I have a tool that provides insight! Love tracking my progress and making improvements in my wellness journey. ### 5/5 — Great conversation starter! *2023-09-16, version 1.122* Great conversation starter! It’s a good addition to my wellness toolkit! ### 5/5 — New I heart app *2023-08-13, version 1.113* This app is junk , as stated in another review looks like written, setup by a child. The original was excellent especially history format and that notes could be posted with every recording for activities, exercise done before that may have had a bearing on results, etc. I would pay for the original app in lien of it being free if I could replace this junk app with the original. I tried restore the original on my I pad form I cloud but this junk was in I cloud. ### 5/5 — Awesome *2023-02-22, version 1.104* This is a really cool device. The Internal Age app is my favourite from iheart, I love seeing my internal age come down over time. Currently at 25! ### 5/5 — Easy to use *2022-11-21, version 1.102* Got this because it is the most precise oximeter available (200sps). Really like being able to see my internal age progress over time, and the ability to write notes to describe each result. I am learning more about what my internal age means through iheart’s website resources. Excited to use the new apps with this same device! Glad they are expanding the value of this tool. ### 5/5 — Impressed *2021-11-02, version 1.100* Honestly other than it being landscape mode, it works great. The technology incorporated here is amazing! ### 5/5 — Great app! *2019-05-16, version 1.91* It was very easy to install and use. ### 5/5 — Interesting app and easy to use *2018-07-16, version 1.85* This app is super easy to use and provides information that helps me learn what works best for my body to improve internal health on the long term. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
