On Yay! you can change the font size in your posts to capture how you are feeling at the time.
By changing the font also, you can express even more emotions.
■Steps (For iOS and Android)
1. Tap the icon on the bottom right of the timeline or profile screen
2. A form for posting will appear, so enter the text
3. Long-press the Send button
(Screenshot: Example for a post (maximum size))
The longer you hold the long-press, the larger the font size becomes for the text in the post
If you would not like to post with the maximum font size, you can cancel your post by moving your finger away from the Send button before releasing your finger from the screen to end your long-press.
