If you like the application, please consider to donate. It will help me to pay the bills (Google play store, Apple store, hosting, domain, beers 🍺 ...) but the most important it will prove that my work is useful and I will keep maintain the app, add features...
You can do this inside wako, in settings > contribute.
If you really don't want to contribute through the app, you still can do it via PayPal.
If you do so, please donate at least 15€ and let me know your trakt username in the PayPal message, I will add you a manual life time subscription (you will receive a push notification in wako to let you know it's been took care of).
