App "rendezyou" for organizing appointments by using phone numbers

Hi there,

I'm new here and developing over the last 3 years as a solo developer the app "rendezyou".

https://rendezyou.app/rendezyou-englisch.html

rendezyou is an app for organizing events or appointments by using phone numbers from your phone book.
I know that there are plenty of event and appointment apps (like Outlook, Apple Invites etc.) out there, but they rely on email addresses or sharing links. And I was frustrated with WhatsApp for organizing appointments just to organize them by using phone numbers from my phone book.

Currently I'm using rendezyou with friends and my family to organize things.

rendezyou can be downloaded in Germany, France, Austria, Switzerland and the US from the Android Play and Apple App store.

Phone numbers are stored on the server encrypted :-)

If you don't like it, you can delete your account within the app and all of your data will be deleted on the server.

Feel free to test it and give me feedback about the idea / improvements.

Cheers,

Uwe
