Pretty good app! Open Validator is solid for analyzing info. I’ve enjoyed the ease of use, but sometimes, it feels like it doesn’t go deep enough for more complex tasks. Still, worth it!

I like what Open Validator is trying to do, but there are moments when it feels a bit clunky. The features are useful, but I've encountered some hiccups along the way. I hope they improve it further.
