Love the concept—but problem continues with no signaling at key rates. Silent mode is off—haptics set to normal. Help? I’d love to make this work. ### 2/5 — How do I review a run? *2021-07-09* I ran a 5K this evening with the app but there’s seems to be no way to review the run after the fact. I agreed to the location sharing hoping I’d be able to upload the run to Strava but the Apple Watch app offers zero way to see anything after the fact besides the summary which I mistakenly (I guess) just exited out of without looking at it. I did save the run though, but I have no clue where that goes. It’s disappointing to say the least. ### 3/5 — Concept Good But alerting while running *2021-03-20* Good concept but I don’t get the alerts while running. Haptics are enable and I’m not in silent mode. I have a 3 series watch. ### 4/5 — Zone violation alerts not timely *2021-01-22* Dear Tongqing, I’m not sure how to contact you and am writing here instead. Your app has the right design that I need for MAF training, namely, to stay within a narrow heart rate zone just below the MAF threshold. Unfortunately, there are a couple problems and I was wondering if there is a way around them or you could implement the next version so as to avoid them: (1) The alerts for exceeding the high bpm or dipping below low bpm don’t automatically happen, i.e., the alert happens only if you happen to turn your wrist and look at that watch when the limit has already been exceeded. At first I thought, looking at the watch was making my heart rate go up, but it’s pretty clear that the app seems to not have a way of alerting if the display sleeps. Is this expected? Having to look at the watch all the time is very frustrating and defeats the whole point of the app for me, not to mention that it is even harder to do it in winter. (2) Often the app displays no value but instead something like “1..” as if it’s not sure of the latter two digits of precision. What exactly is going on in such situations? You can contact me at avenka at gmail and I’d be happy to offer more suggestions and/or (freely) help with implementing them. Thanks. **Developer response:** Hi Avenka, Many thanks to your feedback. Here are the two issues you mentioned, and below is the tips and bug fixing. (1) The alerts for exceeding the high bpm or dipping below low bpm don’t automatically happen, i.e., the alert happens only if you happen to turn your wrist and look at that watch when the limit has already been exceeded.

Yes, watching the watch to get alerted is not the design. Usually, it dose not need to watch it. It will give vibratility tips when high rate be exceeded. If not, there are maybe a setting need to check. You need to check whether 'mute' mode is set on Watch. Open your Watch App on iPhone and go "Setting" ---> "Sounds & Haptics" to enable "Haptic Alerts". If doesn't work, maybe you need to disable "Silent Mode" (2) Often the app displays no value but instead something like “1..” as if it’s not sure of the latter two digits of precision.

Sorry for that, it is a display bug on some devices. I tested on my Watch5 while it does fails on Watch3 with 38mm. I fixed this bug and resubmit to Apple Store. Many thanks, if you have other suggestions, I would like to implement since we are liking running and wish you good health.

Any chance to add a setting to the app to enable water lock mode? I want to try this with swimming in zone two and it would also help with running in the rain. Thanks! **Developer response:** Many thanks for your reply，I would like to consider it in next weeks. ### 5/5 — Very sample *2021-02-12* It takes long time to find a heart training on AW like this. The design is very sample but useful. **Developer response:** Glad to know you like it, many thanks. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
