[MacroFactor] Improve free trial management and payment clarity

I started to track calories recently and after a month or so, I realised it has a section where it breaks down the vitamin and mineral content of your food. I largely eat whole foods I cook so I think it's likely fairly accurate, and it has some great information. I feel like I'm drowning in info on all the things I can supplement so it was really helpful seeing what I'm not getting from my diet. In my case, I found I get lots of most things except vitamin C, E and calcium. It also showed I get very little choline. I'm going to start supplementing those specifically, and see if they help. I have had blood work and I'm supplementing iron, B12 and vitamin D based on that but I don't think these others were tested for - I don't see it on the test results. I feel a lot better taking something I know I'm likely not getting enough of in a dose that just brings me into the RDI, it feels a lot less likely to have side effects. I'm using the macro factor app, I'm sure you could do this with other apps however. I'm only using that because I didn't track how long my free trial was and accidentally paid for a year 😒
