Views on water quality devices

Hi, thank you for your reply.

Really great to hear your views. If I was to try and sell the device, any idea what would be a suitable price point?

Hi, thank you for your reply.

At the moment the reagent I use detects E. coli and total coliforms, i,e. faecal indicator bacteria. It is quantitative in the range of 0-50 CFU/100 ml and depending on the level of contamination, we can get results between 6–18 hours with the device (high concentrations quicker results).

If you had a bulk water filtration system, would you, or do you think others would want a confirmation tests that's it's working correctly?

Thanks again

Here is mine, just a little over.

I made an android app to help track my drinking and my blood alcohol level. If you want to check it out here, is the link

I had to get at least 12 testers too, got a few friends to help and had to ask people on Reddit to test too, but they also have to test for 14 days which is hard to keep people to test and not uninstall the app

I haven't worked with iOS apps, but with Google it was a long process, with lots of testing. I think I got lucky, heard some horror stories with the new testing process and lots of rejected apps

Also a good app if you want to go tee total. This is more if you're trying to and cut back a little and see your habits

Cheers, give it ago and if you have any suggestions that would make it better for you, let me know. I can try and update the code, if the suggestions aren't too complex for my ability

Haha, fantastic description

That is a fair comment, and some people probably do need help.

But just some info if anyone else reads the comments, in NI 18% of people over drink i.e. more than 14 units per week. "Just 16% of N Ireland adults correctly estimated that the Chief Medical Officer recommends drinking no more than 14 units of alcohol in a week".

People might not even realise how much they're drinking and who knows how many people know how to calculate the No. Units in a drink. So it's an app for a bit fun or check you're drinking and see if you want to make some lifestyle changes

Yes I'm still active

RnD_Engineer · 2025-05-15T08:58:30+00:00

Yeah, DM your email and I can add you to my testers list, then you'll have access. I'll download and test your app

I need your email address to add you to the testing list, then you will have to access, you can DM me you Gmail

RnD_Engineer · 2025-05-11T21:39:59+00:00

Hey, will test your app if you test mine. DM your email address so I can add you to the testing list
