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/

A light comes on in your dashboard. An amber horseshoe with an exclamation mark in it. You have no idea what it means — and no idea what it's called, which means you can't look it up. Your manual knows. It's 532 pages, it's in the glovebox, and it calls that thing a TPMS indicator, a phrase you have never heard in your life. Xgest closes that gap. Ask "what's the orange horseshoe light?" and it works out you mean TPMS, finds the page, and tells you what your manual says. Then it shows you the page. Every answer points to the page in your own manual it came from — Xgest never guesses. ASK IN YOUR OWN WORDS You don't need to know the right term. That's the whole problem — the manual speaks manual, and you don't. Searching a Honda HR-V manual for "orange horseshoe light" matches zero of its 532 pages. Xgest translates first. NO WORDS AT ALL? PHOTOGRAPH IT A symbol on a dial. An unlabelled button. A light you've never seen. Point the camera at it instead of trying to describe it. EVERY ANSWER CITES A PAGE Tap the citation and the real page opens. Not a summary of the page — the page. So you never have to take our word for it. THE ONE IN THE DRAWER Some manuals were never a PDF and never will be. The card that came with the dishwasher. The booklet for the mower. The folded insert in the box. Photograph the pages and Xgest reads them, on your phone. Older scanned PDFs — pictures of pages with no text behind them — work the same way. ONE THING, SEVERAL MANUALS The owner's manual and the nav supplement. The use-and-care guide and the installation sheet. Keep them together under the thing they belong to. ASK YOUR WHOLE SHELF (Plus) Don't know which manual has the answer — or which appliance is even beeping? Ask once. Xgest searches every manual you own and tells you which one each part of the answer came from. Unlimited manuals and shelf-wide ask come with Xgest Plus, a one-time purchase. New in 2.2: Xgest now surfaces one cited fact about something you own — every day. Tap any manual, or browse your whole shelf, when you’ve got a minute to kill. YOUR MANUALS STAY YOURS Xgest reads and indexes your manuals on your phone. They are never uploaded. When you ask a question, what leaves is your question and a few paragraphs from the handful of pages your phone picked — never the manual. Pages you photograph never leave at all. No accounts. No sign-up. No ads. Nothing tracking you.

Verdict
The clearest difference is in-app purchases: Xgest at none against Pool Math by TroubleFreePool's 1. Xgest also leads on update cadence (every 4 days vs fortnightly). Pool Math by TroubleFreePool's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.6). On price and ads there is nothing between them.
