SilverTimer
Read full descriptionHide full description
Anyone who has ever dealt with the production of colloidal silver knows the "problem" based on the amount of water to be treated and the desired PPM to determine the required switch-on time for electrolysis. This app takes the determination of this value on the basis of tables and calculates it accordingly after entering the values for the water quantity and the PPM. After pressing the start button, a counter starts to run down. At the end, when the desired PPM are reached, you will receive a notification. The operation is largely self-explanatory. Apple Watch is also supported. If you have any questions, please visit my support page.
