Small fixes and improvements.

A clearer free trial and a winter guide. • The Premium screen now shows your actual free trial length and the day it ends, straight from the App Store, and only if you can use the trial • If you start a free trial, DoseMyPool reminds you 2 days before it ends • New free guide in Fix It: Closing Your Pool for Winter, with the steps from water balance to cover

Your in-app guidance now matches dosemypool.com. • The glossary uses the same ranges as your targets: pH 7.2 to 7.8, alkalinity 80 to 120 ppm, stabilizer (CYA) 30 to 50 ppm, calcium by surface type, and salt by cell brand • Free chlorine is explained as a minimum plus a target range for your CYA • Filter pressure now says to clean when the gauge climbs about 25% above your clean reading, the rule in Trouble Free Pool's checklist, instead of a flat 8 psi • Shock Mode asks for a re-test three or four times a day, no more often than every two hours • Shock Mode's swimming advice now says to follow the product label and to swim only when you can clearly see the bottom of the deep end and free chlorine is between the minimum and the shock level • The weekly test reminder now shows the CDC's advice to test a pool's chlorine and pH at least twice a day

Your targets now follow the same sources as dosemypool.com.

Translation fixes. A few labels on the Chemicals on Hand screens and the filter pressure chart were still appearing in English for German, Spanish, French, Italian and Portuguese. They now read correctly in every language the app supports.
