Shame. ### 5/5 — Best app. For people with asthma and COPD. *2023-11-21* I’ve been using this app for the last four years, the sensor don’t work anymore but the app does. This app help me remind myself about taking my medication and not forgetting. When I do forget, I look at the app if I took it or not. Every time I take my medication, I have my phone and the app open like that I don’t forget to put the dose in. You have to create other gadgets for others medication that the sensor don’t fit. Like TRELLGY, I know it’s a cartridge. Definitely be hard to create a device. Thank you for creating this app. ### 5/5 — Problem with upgrade ? *2023-11-04* Hi I’ve been using Propeller , and it has been helpful keeping track of my meds . Although , I’ve used the propeller up until the sensors stop working . Than I have a heck of a time keeping track , I move my times around the clock taking them at odd times like , 1:30am then the second dose 1:30 pm , 7:30 pm , 11:30 pm , etc . I’m not complaining about the times taking my medicines , I keep a log now on when I take them at different times , and if I miss a dose or two , I stop taking it , because I can’t remember if I took it or not . I emailed that the propeller wasn’t working right , now I enter a dose on my medication and it accepts it to save , but now every time I enter a dose the it won’t let me X out of the page , and I just shut off my phone to get back into the propeller App . I just got this phone a couple of weeks ago , and it worked ok until I sent an email of the problem . I still have my old phone and it does the same thing on that phone . It enters 12 times the same dosage I just took and the time is the same also 12 times . ? Bug fix ? I don’t know , upgrade again ? I don’t know , I hope someone can look into it thanks ### 3/5 — Problem with upgrade ? *2023-11-03* Hi I’ve been using Propeller , and it has been helpful keeping track of my meds .

Thank you it’s been a long journey much of which is due to your company!! I’m can not use the generic so I’m signing off. Namaste’ ~LRRJenkins ### 3/5 — Nuisance *2023-01-08* I have found the propeller to be an added nuisance to my routine. I am generally good at taking prescribed medication in a timely manner. I had hoped it would help me determine why I have sporadic productive coughing each day. However, I don’t know my “triggers”. Nor do my doctors apparently. “Symptoms” don’t include “productive” cough, which is my daily problem. I am on multiple medications related to my condition and the propeller can only measure 1, so it is a nuisance to have to enter every thing every day. ### 5/5 — Best App Ever *2022-11-29, version 7.17.0* This keeps me updated on the weather conditions outside and how it may contribute to aggravate my asthma. Has reminders for certain meds and lets me log reasons for inhaler usage to help me keep aware of my asthma triggers ### 4/5 — Amazing App! *2022-11-09, version 7.16.1* I’ve always thought inhalers should have a sensor! My only complaint, when I take an inhaled long acting medication Propeller counts this as inhaler usage in the Health App. I don’t think this should be happening. Inhaler usage in the health app should only be used for rescue inhaler usage, not inhaled control medications. ### 5/5 — The best app ever *2022-10-16, version 7.14.0* Honestly, this is the best app you could ever have to both help remind you to take your inhalers, but also track your usage so it’s easier to show your providers how often you are using your rescue inhaler and whatnot. I have had this for a while now, and I will always use this. ## Frequently asked questions about Propeller ### What does this app do?
