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. Pool Math's great features include: • Calculators for pH, Free Chlorine, Calcium Hardness, Salt, Total Alkalinity, Calcium Hardness, Borates, CSI • Track Maintenance: Backwashing, Vacuuming, Filter Cleaning, Filter Pressure, SWG Cell %, Flow Rate • Track Chemical Additions • Track Weather conditions with your logs • Calculate the Effects of Adding chemicals to your pool • Bleach Price Calculator - Find the best deals on bleach easily • Summary page to see an overview of test results and chemical additions • Data backup / Export Premium Subscribers get access to these additional features: • Unlimited Test Log History Storage • Maintenance Reminders • Cloud Sync/Backup • Sync across multiple devices • Unlimited Pool / Spa Configurations • Test Log CSV Import / Export Pool Math Premium Subscription details: • Auto-renewable subscription • 1 year for $7.99 USD • Your subscription will be charged to your iTunes account at confirmation of purchase and will automatically renew (at the duration of 1 year) unless auto-renew is turned off at least 24 hours before the end of the current period. • Current subscription may not be cancelled during the active subscription period; however, you can manage your subscription and/or turn off auto-renewal by visiting your iTunes Account Settings after purchase. • Privacy Policy & Terms of Use: http://poolmathapp.com/privacy/

Some job messages just feel off — a recruiter who only talks over chat, an offer before any real interview, a request for your bank details on day one. SecondLook is a calm second opinion. Paste a recruiter email or text, or drop in a screenshot, choose where you are in the hiring process, and get a plain-language read on what doesn't line up. It works entirely on your device, with no account and nothing to sign up for. What you get • Every flag explained — what was found, why it's unusual for your stage, and what to do next. No mystery score. • Checks for the patterns real job scams share: pay-to-start fees, gift-card or wire requests, ID or bank details asked for too early, fake-check schemes, chat-only interviews, offers with no interview, lookalike sender domains, pressure and urgency. • Stage awareness — an SSN request is ordinary onboarding paperwork, and a red flag at first contact. SecondLook knows the difference. Private by design • The message and any screenshot are read on your device. No account, no tracking, no analytics. • A saved check keeps only which patterns matched and the date — never the text of your message. • One optional feature, Deep AI Check, sends a message to an AI service for a closer look — only when you ask for it, after a one-time explanation. Everything else stays on your phone. Made to pass along • Forward SecondLook to someone who's job hunting. A suspicious offer takes about ten seconds to check. SecondLook points out patterns commonly seen in job scams. It can't confirm that a message, company, or person is genuine, and a clean result isn't a guarantee. When money, documents, or personal details are involved, always verify the employer through a channel you trust.
