Attractive design with some flaws
Overall nice to use, and the design of the visual guide is great. However, scrolling through focal lengths is quite laborious given how many decimal pointed focal lengths there are, which I personally didn’t even know existed. Also, while you have an option to choose different sensor sizes, it doesn’t distinguish between different APS-C sensor sizes, e.g. 1.6x for canon and approx 1.5x for Fujifilm. No idea how much this effects the calculations but it’s worth noting. Overall still a pretty convenient app.
