While this app seems sensible, I checked out the github developer account DimensionDev and it looks like their primary product is something called Mask which is something about "Web 3" crypto/NFT integration ... looks like they're a libertarian crypto grifter cult to me. They also have a gaudy, nonfunctional company page whose copyright notice reveals that is owned by a Chinese parent company with it's own stale, uninformative web page.
It's open source, and yeah, maybe they thought they'd make something actually useful ... but the source is full of red flags.
