Free. Just enjoy it.
Udfyld is free. That's the whole app and every feature, with no ads and no subscription. Just use it, and students: keep your money for noodles.
If you're doing alright, you can become a supporter inside the app. That gets you the show-off icons: a few extra app icons, so your home screen knows you're not just another freeloader. Nothing gets locked, and freeloaders are still very welcome. Peter isn't judging. Much.
Your files never leave your iPhone.
Udfyld has no account, no ads and no tracking, and it sends nothing over the internet. It saves a copy and never touches the original unless you choose to.
