It glitches and closes, won’t record answers, fails to open, freezes without warning. It’s so frustrating, it can take hours to record the data you need and then you end up giving up anyway ### 1/5 — Rubbish *2026-07-16, version 3.78.14* App keeps closing when filling in the forms or doing the breath test or freezing. It can take anywhere between 30 mins to 2 hours to do a simple 5 minute task, have deleted it and reinstalled it but the problems keep persisting. Get it sorted please ### 1/5 — Constant crashing *2026-07-02* I have to delete and reinstall the app every single time to use it. ### 2/5 — Very Glitchy *2026-06-12* This app crashes almost every day. I have to delete and then re-download it all the time. ### 2/5 — App crashing *2023-08-25* As of 8/25… the App is crashing. Can't open. Please fix. ### 1/5 — Reset my password *2023-07-05* I have repeatedly asked for a password reset. I never get an email back. ### 3/5 — Login problems *2023-05-11* I can’t seem to log in with both usernames. I change my password last week that went through. Now I am unable to log in. I never had to put in a username and password in the past. Now it’s very confusing to log in. ### 4/5 — Personalization needed *2021-07-15* The app is ok. I wish there was a way to set my own time reminder for taking my Jetson & be able to pick the notification sound as well (like an alarm clock). Also, would like to be able to delete my “messages” in the inbox once it’s been read. And lastly, the app needs to be able to let each person set their start date for the next bottle of Jetson. I signed up for the app and it had me starting my Jetson before I had even received it yet. It says I have 2 days left in my cycle, but I have more pills left than that. Needs to be able to be personalized by the individual user. ### 5/5 — Love HUMI panel! *2019-04-08* Thanks for letting me participate!! ## Frequently asked questions about Linkt Health ### What is Linkt Health used for?
