Petri Dish Agar
Grow something beautiful. Take notes.

About Petri Dish
Petri Dish Agar is a small science laboratory for your pocket. Seed a virtual agar dish, tune the conditions and watch colonies grow through deterministic simulation — then behave like a scientist about it: record experiment notes, log reactions and compare runs. The simulation mathematics are seeded and reproducible, so the same setup grows the same way twice, which makes real experimentation possible. The manifest explicitly removes the Internet permission: this lab is entirely yours.
Key features
- Deterministic, reproducible colony growth simulation
- Experiment notes and reaction logging
- Tunable conditions per dish
- Zero permissions — Internet explicitly removed
- Fully offline

Illustrative development previews — genuine screenshots will appear here as the app matures.

Reproducibility is the game mechanic
Seeded simulation means every run can be repeated exactly — change one variable, grow the dish again and the difference you see is the difference you made. That is the scientific method, disguised as a rather hypnotic screen.
Development status
Petri Dish Agar is roughly 45% of the way to its first public release. It will appear on Google Play when it's genuinely ready.
Privacy & practical details
Privacy at a glance
Petri Dish Agar requests no permissions at all — the Internet permission is explicitly removed in the manifest. Experiments and notes stay on your device.
