I want to make very simple modifications to existing images; add a few lines here and there, or perhaps change some colors or very basic stuff like that. What product would you recommend? Ideally something not-too-expensive and that works with MacOS. In the past I've used Inkscape but I'm hoping there's something simpler to use? I know some people use canva.com, is this tool worth exploring for my use case? Thanks!

I'm building a product for rock climbers to improve by focusing on mastering their climbing technique instead of focusing on increasing pull-up count or other random physical attributes. I want to start with a small number of beta-users. There are a few subreddits that have the exact audience of my product. What would be the best way to reach out? 1) A new thread talking about the idea? 2) Reaching out via DM to ppl that, based on their comments, seem like the right audience? 3) Ads? For 2), would it make sense to first send a message asking if it's ok to pitch them something they might be interested in? I hate when I'm pitched something off-the-bat and I'm unlikely to even respond, even if it's something I'd otherwise be interested in. Thanks!
