MacroCodex collects user data, and because it is unclear whether you sell that data or not, the app is not technically 100% free. Frankly, it just looks like a low-effort, "vibe-coded" application. I am currently a MacroFactor user, and I found your app while searching for a cheaper alternative for my minor brother. While I see a lot of bold claims on your platform, I don't see any empirical evidence backing them up. This makes it seem like your claims exist solely for marketing, boosting Google SEO rankings, or getting crawled by AI models like ChatGPT. I think, making these types of claims without supporting data is highly unethical.
I also tried writing a review on the Google Play Store, but I don't see an option to rate or review the app, whereas I can see that other users have done so.
