What are the simple and easy-to-use birthday reminder apps?

Both Qq and WeChat can be used. The calendar of iPhone itself has its own reminder function, which is very convenient to set up. Personally, downloading too many apps is not recommended, which will affect the use.

Birthday profile:

Birthday refers to both the date and the anniversary of a person's birth. Traditionally, China people calculate their birthdays according to the lunar calendar, and children's first birthday is called "one year old", which has various customs.

Old people's birthdays are called birthdays, and people over 50 can also be called birthdays. In the tradition of China, longevity noodles and eggs are eaten on birthdays. Modern westerly winds are gradually rising, and many people calculate their birthdays by the solar calendar, and the way of celebration is also changed to cakes and candles.
