Anyone know anything about what's up with preev?

Looks like the preev.com site, has relapsed from an old disease, I saw this happen in 2019, like this person said.

It seem that Preev is down for the moment, or their server on Heroku is not yet paid, or transferred their app to Heroku.

But I saw the discussion a few days later, preev.com, is active again after the update, maybe you have to be patient and see in the next two days.

@The Pharmacist, suggestion from @NeuroticFish, I think it makes sense and good to try, if you want to try other alternatives, name tofu.

Although preev is up and running, I'll also post the link for a converter I use now and then (not mine), especially if I want to check altcoins or the prices in my local fiat currency.
It's https://www.mycryptobuddy.com/CurrencyConverter (or shortened to http://tinyurl.com/preev2)
