Never heard of them before. You've been away for the forum and the first post you make is about relatively new projects with few downloads on the app store while there are dozens of alternatives on the market. It is hard to feel you're not deliberately shilling them just like your other projects. If you do want to shill it is fine, but you should be upfront about it.

If you truly want to look for more information about it, better wait until it becomes popular and has a decent amount of users before you start considering using them. At the very least, you should check out their legal information. As of now, you can at least confirm that it is a website/app published by Exechain. This company is also not popular as far as I'm aware, not sure if you can even trust their public filling information.
