Contacts & Family Members

One interesting and convenient feature of WhatDays is the synchronization between contacts. You can see your friends interacting with each other within the card making app. For example, if one sends another a virtual gift, you will see it too. You can keep the magic going and remember to congratulate all of your friends on their birthdays and other special dates. This is a great way to keep up with your friends and their personal achievements. You can also add family members to the app.

When somebody congratulates you through the postcard app, you can respond to them by sending a sticker or an emoji. There is no need to write individual thank you notes for everyone, though you can easily do that through the birthday app too.

Holiday Reminders

Forgetting the date of birth of someone who is important to you is a horrible thing. Avoid that and attract some happy birthday magic! The postcard app offers a birthday reminder feature and birthday calendar. See when your friends and family members’ festivities are and never forget another anniversary again. This works for all occasions. Make a countdown till the next event through our happy birthday app.

How To Congratulate Someone?

It’s easy and you can totally do it on the run! Simply pick a card and choose who you’re going to send it to. If the contact you’re trying to reach hasn’t installed WhatDays yet, they will receive an invitation to join our community. You can also share this link via messenger.


We are working day and night to make this application easy to use and great, with a wide variety of postcards and wishes. If you would like to help us improve our functionality by providing feedback, please don’t hesitate to reach out! We are currently working on adding horoscopes and toasts to our selection.
