App is clunky and inaccurate

Received my Pul bottle and smart cap today and got the app to set it up and start logging the day’s past drinks. It doesn’t let you put in past times for drinking, even though the option is there to wind back the time. It doesn’t stick. I’m also confused at the drink selection. You want to log an Old Fashioned for hydration but there’s no standard Tea (only black tea) or lemonade or other normal, less specific drinks? There’s no option to add your own drink. For example it’s just 1% Milk or Almond Milk, nothing in between. My other gripe is that the daily drinking progress doesn’t update even after adding drinks in the log. I’m stuck at 1% for the espresso I logged even though I logged 8 oz of “almond milk”. I’m not even sure or able to verify my cap is properly connected even though it’s fully charged and present in the app. It just says “Disconnected” and I have yet to see the cap light up to tell me I’m drastically behind on my hydration as the app says. Not sure I’ll be keeping this even though the idea is great. This just seems like a nice water bottle with no working technology behind it. The app itself hasn’t been updated in over 7 months, which tells me not much is being invested there and that any improvements will be a long time coming. Too bad.

New app messed everything up

New app version came out beginning of February and was riddled with bugs. Made my experience a total mess by losing all my past drinking data and not keeping my wake and sleep times among other issues. A new version came out mid February still full of bugs and instability. Support seemed to care at first, but then no word from them since the last app version which is almost 3 weeks ago. Loved this smart cap but now it’s complete trash with no word of when all the issues will be resolved.

Solid app

Very happy with this app so far. Clean and easy to keep track of my water intake. Wish there was a widget for iOS though!
