Is there any free stacking software on Android?

I love taking pictures of the Orion Nebula but i have a dob so the stars trail on long exposures, is there any free Android stacking software?

Not that I'm aware of. For your application I assume you require a simplified program to stack smart phone images only.

For serious  deep sky stacking work you will need powerful processing power and have to tune the settings and parameters, create and add dark, bias images. Remove outliers and so on. A smartphone is then a less suitable environment due to lack of processing power, small screen and more limited human interface.

Mentions stacking in description, never managed to try it though.
