If you shoot landscapes on colour negative film an app will do just fine.
Use common sense, like point it to relevant areas in your image.
I have a free one for iOS, think it's called just "Light Meter", it does the job well.
If you shoot with slide film and the light is "complicated" / difficult to meter a proper spot meter would become useful.Good luck with the Bronica!
They also did a nice 6x45 rangefinder - go check if your guy has one of those!
I never shot with one of these myself, but heard good things about them.
Back in the day I intended to buy one, but they were still very expensive then, so I shot friends' Mamiyas and Hasselblads instead (still do, haha!)..
Not sure what makes you think you'd need a spotmeter for landscapes.
Yes, you will definitely need a light meter of some sort - but (depending a bit on how forgiving your film is) it's not rocket science - in a lot of cases an iPhone app will do the job just fine - especially when shooting landscapes, and especially when shooting colour negative film (err on the side of over-exposure, and use common sense - point the thing a the stuff you want to meter, not "somewhere").
