This may be old news, but I just downloaded a neat little app on my phone called E-Smoker Calculator. It is a calculator for DIY juices, but it also will calculate your nic levels of mixed liquids. This is great for people like me who are trying to slowly cut down their nic levels over time without making a huge jump between levels. The coolest thing to me, though, is that it lets you enter information into the settings page about when you quit, how often you smoked, and how much you spent on analogs. You can then enter your prurchases to date, and it uses this information along with your original settings to tell you a break even date, how much you spend on average per month on vaping supplies, and compares that to how much you used to spend on analogs. Nifty little trick!
