I think I saw an example where you said you use it to answer questions like 'How many curls did I do with these weights last time' [1]. That was from a couple of years ago, and I'm assuming you are the commenter there. If that's correct, do you have a way to make this system portable? I feel like the place I'm most likely to need to answer such questions would typically only have my phone available.
I greatly appreciate the data you're collecting and the overall method of doing so. However, I'm curious to learn about the portability of this information, and how you access it when you're away from a computer with vim.
