Preferably lesser known but game-changing apps that are able to be bought one-time and put all others to shame.
To help clarify your thinking, which apps have produced such an outrageous level of value (regardless of one-time cost) to the extent you believe it should be #1 in its category, not necessarily #1 app ever.
We’ll do a seperate thread for Mac, Windows, Linux, Android, etc but let’s stick to iOS for this one. Thanks Lemmings!
Iirc the only main downside to all these apps is that you get a single answer, when it’s usually more complex than that.
Seek/iNaturalist are great. I prefer the report style of iNaturalist and how it gives me a list of options, which I can use to try and narrow it down.
E.g. if I take a pic of a flower that looks like a dandelion, it could be a common dandelion, or hawkweed, or burnweed… and of those there are a dozen sub species. Knowing which one is native is really important.
Tldr yes
