A calmer way
to read pH.
Dip your indicator. Point your camera. Read the number. That's the whole lab.
How it works
Add a drop of pH indicator to your sample. The color it turns is chemistry speaking.
Frame it in the circle with the gray card beside it. The card lets the app cancel out your lighting.
Press Read pH — the color becomes a number, with an honest ± on it. If the color looks like nothing it knows, it says so instead of guessing.
Prepare a solution of known pH (verified with a pH meter or a fresh buffer), add your indicator, frame it like a normal measurement, enter its pH and capture. Aim for at least 8 points spread across the range you care about. Several captures at the same pH under different lighting make the model tougher.
