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 ### 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! ### 4/5 — 良い商品だと思います。 *2023-12-08, version 1.131* 測れましたが、プロフィールで身長を登録したのですが、プロフィール一覧から再度確認すると身長のセンチメーター数がクリアされています。 これはバグなのでしょうか？ ### 4/5 — Great device but.., *2023-11-18, version 1.131* The great and simple device to use. 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. ### 1/5 — Useless *2023-10-21, version 1.129* App now just crashes so my £100 piece of hardware is now useless. Pathetic. ### 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. ### 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! ### 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. ## Frequently asked questions about iHeart Internal Age ### What does the iHeart Internal Age app do?
