Pool Mate captures with a photograph the color of the pads of a swimming pool and or spa test strip to give near instantaneous results and recommendations. Thus no more guessing the pads color and no more manual calculations!It does this without the need for a special background or special strips and does not need to upload the image to be processed elsewhere as with other apps.Why not test on a regular basis, as you get 50 strips and they expire in 1 year you may as well use them by testing weekly.Tired of going to the pool shop and leaving $80 out of pocket? This happens as most people put off testing the water and then have to make large corrections when things don't look right. Regular testing resulting in small adjustments will go a long way to prevent that ever happening again.For Australian users all three supported strips can be purchased from Bunnings. You can also get all the chemicals you need there as well. The App has been written by a Pool Owner for the Pool/Spa owner. I think you will like it.
