Nice! Congrats on shipping. Don't be ashamed to charge for a good product. Your potential customers will decide if something is worth paying for. The era of growth over revenue is coming to an end, along with an impeding recession!
Thanks! It only took me 11 years to get the courage to at least _attempt_ to ship something. And although I am no position to look for investment, as in I don't have access to a VC/investment environment, I can dedicate at least 2-3 years to the product, bootstrapping it.
