costs £4.59 to buy it once in the UK, in the US play store it's $1.99/month or $14.99/yr. lol. I would have bought it for £4.59, as it is, uninstalling.

I've this app installed on both of my phones and the exposure readout is pretty much accurate with ~±0,1 EV variation on both. But, with mid to very complicated scenes, you may get a few different readouts.

Total junk. Grossly over exposes, all the time. When my hand held meter suggests 1/125 at f5.6, this tells me 1/125 at f2. Managed to ruin most of a film by stupidly relying on this.
