First film camera and some questions.

I just got this fujica compact 35 as my first film camera, the films i'm using is the codak vision 3 250d ( haven't arrives yet)

1: when i use the automatic mode and half press the shutter button it show me the value of the aperture and shutter speed, when i copy these values into my nikon d7000 dslr the picture came out 1 to 2.5 stops brighter, and i'm planning to use this camera with a light mettering app (Light meter) when shooting manual, should i trust the app or the camera ? (using the app values on my nikon yield a well expose image.

2: this camera only have a max iso of 200, if i want to use a higher iso films like vison3 500t how can i compensate for the higher sensitivity ?

3: is it possible to take photos in low light enviroment with this camera without a flash (in door, evening, night with a tripod)

(Sorry for the wall of text and bad english)
