This is something i discovered few days back.
There is something called as a Smart Asthma Inhaler by Aerobit Health. I have to say, its just great. I had requested them for a demo, and i jumped on a call with one of their executives.
The idea is lovely. its basically a clip-on, an accessory(like a cell phone cover) onto asthma and COPD inhalers. it has sensors and bluetooth. it analyzes the inhalation score and gives it to you on its mobile app.
it remindes me time to time to take dosage, if i take a dose, it comes on the app automatically.
i would recommend you guys to try that out.
best of luck!
