Hot tub season: dip a strip, take one photo, and get exact doses from the chemicals you already own. Free calculators. No account. Photos stay on your phone.
Dip a strip, take one photo, and DipDose tells you exactly what to add — using the chemicals already in your shed.
WORKS WITH YOUR STRIPS
• Reads the common 4-way and 6-way pool test strips and hot tub bromine strips
• Another kind of strip? Set it up once: the app finds the rows of colors, you say what each one tests
• Each pad is compared with the color chart printed on your own bottle, in the same photo and the same light
• Prefer drops? Type your drop-kit results for the most precise answer
EXACT DOSES FROM WHAT YOU OWN
• Tell it once what you have: liquid chlorine, bleach, cal-hypo, dichlor, muriatic acid, pH Up, pH Down, baking soda, calcium, stabilizer, salt
• Get numbered steps in a safe order, like "Add 38 fl oz of your liquid chlorine 10%"
• Big doses are split ("add half, then test again in 4 hours"), with the wait between chemicals
• pH worked out properly, taking your alkalinity and stabilizer into account
• Small liquid doses also in teaspoons and tablespoons
POOLS AND HOT TUBS
• Chlorine and salt pools, chlorine and bromine hot tubs
• Targets for your water and your surface: plaster, vinyl, fiberglass or acrylic
HISTORY AND REMINDERS
• A chart for every reading, with the good range shaded
• A log of every chemical you added
• Reminders for test days, cleaning the filter and checking the salt cell (Pro)
FREE CALCULATORS
• Salt, chlorine, shock, pH, alkalinity, calcium, stabilizer, pool volume and hot tub chemicals
PRIVATE BY DESIGN
• No account and no ads
• Strip photos are read on your phone and never uploaded
• Your pool's details stay on your phone
