Free - Ecosystem Simulator: Ecojar - Used to be 2.99AUD, now Free @ Apple App Store | Google Playstore
Free ecosystem simulator that used to cost $2.99 — no catch, permanently free!
- From the dev behind WigglyPaint — draw sand, water and plants, add daphnia and fish, seal the jar and see how long it survives without you touching it
- Free on both iOS and Android (was A$2.99 each) — grab it while it's live
- Prefer to try before installing? There's a free browser version at ecojar.io/play
- Great for teachers and parents to play alongside kids, and more creatures are on the way
Even if you never open it again, it's a fun two-hour flight filler for zero dollars.
