1) it's already been live for about a month, so definetly not a week long project
2) I use the app myself every day to reduce screentime so I'm highly motivated to keep the app up to date. When the platforms change DOM elements, or try to distrupt Dull from working I am also disrupted, so I work quickly to fix all bugs
3) There is a 7 day free trial for anyone to test out if it's a "scam". It's not.
a funny reading - if anyone pays for something that won't be around in a week they deserve to be scammed by some scammer.
that said it seems somewhat close to a scam.
but having said those things I'll just note here, knowing you were not the original poster, that people do not in any way deserve to be scammed because they fall for easy to spot scams.
