Yonks – Day Counter for iOS and Android

A day counter app for past and future events, you would like to remember.

  • Ever wondered how many days have been passed since you were born 👶 or since you’ve been married 👰?
  • How many weeks are left until your next vacation 🏝 starts or a project must be finished 👨‍💻?
  • Are you counting the days since you've started your diet 🍏, daily workout 🏄‍♀️ or quit smoking 🚭?
  • How many hours until a highly anticipated movie 🦖 opens or the new awesome video game 🕹 will be released?

Yonks (British slang for "a long time" 🇬🇧) helps you to keep track of all of these dates and their notable milestones. 👌🏻 😌 🎉
