Great reminder for one filter only

This is ok but is it really useful? You could just put the reminder straight into a calendar. There are a few links to help with fitting the water filter, etc but again you could get this straight off the website.

My main complaint is what do you do if you own more than one filter and they need replacing on different days? Your back to using a calendar surely it wouldn't take much to alter the app to allow for more than one filter!

Not much use!

This would be much more useful if it actually gave you a notification to let you know that your filter needs changing ~ which is what I expected it to do!! Instead you have to keep checking the app all the time to see when to do it & as a result I have now gone a month past when it was due!
Easier & more effective to just write it on the calendar the old fashioned way!! Will be removing the app as it's not useful as it is.

Terrible since update

Having installed the App a couple of months ago without problem the latest update wiped out all history! Just as well it did not wipe out the calendar entry! Perhaps the App developers should test their updates before release!
