Thanks! Appreciate the subscription, and I'm stoked you're enjoying the app. I imagine there are others in the FI community that might also get a lot out of it, but I'm not quite sure what the best way is to spread the word. Most subreddits don't allow self-promotion, and same with the Bogleheads forums and wiki. If you or others have any ideas, definitely let me know. Pretty much all my time has gone into trying to make the actual tool, so I haven't done much at all in terms of marketing.
In 15 mins, I was able to get rough answers to questions like:
* When am I financially independent if I keep living the way I do now?
* What if I lowered my expenses right now seeking earlier FI?
* When could I hypothetically stop working by lowering my expenses at the point of retirement?
* How much would be left in my estate?
I bought the lifetime subscription, which seems like quite a good deal!
