## What is ReadMyStrip?

Stop guessing at test strip colors. ReadMyStrip works with any brand of test strip.

Snap the color chart on your strip bottle once. Then scan a strip whenever you test. ReadMyStrip compares each pad to that chart, instead of a generic color table, and shows clear readings marked In Range, Low or High.

Use it with pool test strips, hot tub and spa test strips, and aquarium or fish tank test strips.

FOR POOLS AND HOT TUBS
• Know what to add, with approximate amounts sized to your water volume, in gallons or litres
• Set your sanitizer: chlorine, saltwater or bromine
• Guidance on how pH and alkalinity adjustments affect each other
• Warnings for high sanitizer levels or no sanitizer detected

FOR AQUARIUMS
• Readings from your aquarium strip's own chart
• Warnings for ammonia, nitrite and chlorine
• Readings and warnings only: ReadMyStrip doesn't recommend aquarium chemicals

FOR EVERY TEST
• History with notes, so you can see what changed and what you added
• Copy or share your results
• Send feedback right from the app

Recommendations are approximate guidance and don't replace professional water testing. Always follow your product's label, add chemicals a little at a time, and retest.

### 5/5 — FINALLY!!! Best App for my Pool

*2026-08-25*

Updated 8/20

Thank you for history and notes section! Now everything I am looking for in ONE place!

Still the most consistent reading of my strips the 5 apps that I have tried. 

Thank you for listening to feedback and making these improvements.

**Developer response:** Thanks for the detailed feedback. You made some great points, and we just released an update that addresses them. There’s now full scan history for new readings and notes on each reading, so you can record what you added to your pool and compare it with future tests.

I’m hoping this gives you what you were looking for to track your additives, but if it doesn’t, let me know what we’re missing.

Thanks again for giving ReadMyStrip a try!

### 3/5 — FINALLY!!! Best App for my Pool

*2026-08-17*

Edit: third day using this app and I have discovered that it only keeps 2 readings: current and last. Not as useful as I originally expected. Still have to use another app to track the trends in my pool. 

I've have been looking for an App that would use my existing strips, scan the strips, and keep the results. I would have liked to be able to make a note about my additives to track  with future test strips. Thank you!!
