Pool Math by TroubleFreePool vs Chill

PoolMath makes swimming pool care, maintenance and management easy by tracking chlorine, pH, alkalinity and other levels to help calculate how much salt, bleach and other chemicals to add. Keep swimming in your TroubleFreePool with Pool Math. Crystal clear algae free pool water is what Trouble Free Pool Math is committed to. Pool Math performs all the calculations you need to keep your chlorine, pH, calcium, alkalinity, and stabilizer levels balanced. Why choose Pool Math over the others? Other apps claim to make testing easy by using test strips and your phone's camera. Unfortunately, this is simply too good to be true. Test strips are notoriously inaccurate and end up costing you much more money in both chemicals and the tests themselves in the long run. Trouble Free Pool believes using a proper test kit is much easier, effective, and economical in the long run. By following these calculations the pool owner achieves and maintains crystal clear water without reliance on the often unproductive advice and unneeded expense from pool stores.

Cold plunging asks you to be present. Our Chill - Cold Plunge Timer App takes care of the timing so you can focus on the moment. Choose your duration, set the temperature, settle into guided box breathing, and keep a private record of the sessions you complete. TIME YOUR PLUNGE Choose a session length from 1 to 59 minutes and select the water temperature for accurate record keeping. Watch the large countdown, hear a gentle chime every 30 seconds while Chill is on screen, and turn on Audio Countdown for spoken time updates and the final 10-second countdown. With notifications enabled, Chill can alert you when your timer completes. BREATHE WITH GUIDANCE Follow the on-screen box breathing animation during your session. You can turn the animation or spoken countdown on or off in Settings. LOOK BACK See completed sessions in your iPhone history, including time in the water and the temperature you selected. Time a plunge on Apple Watch and have it appear in your iPhone history when the devices connect. Watch-face complications can show your plunge count.

Cold water immersion has risks; seek medical advice if you have concerns, and never rely on a timer or alert as your only safety measure.
