You'll be able to see your Tamagotchi's current status here.

The first page will show you your Tamagotchi's Hungry meter (up) and Happy meter (down).
The more hearts are filled the better. Only four hearts are shown, but the Hungry meter actually has six, and the Happy meter has five.
You must feed your Tamagotchi to fill their Hungry meter.
To fill their Happy meter, give them snacks or play with them.

The second page shows their discipline (training) level.
The discipline level will go up as you answer the discipline calls your Tamagotchi makes.

You'll also be able to see the Gotchi points you have on this page on the rerelease.

You'll see three things on the third page:
Your Tamagotchi's age. (It increases every 24 hours.)
Their weight, which increases when you feed them and decreases with games.
And their name.

On the fourth page you'll find their gender and the current generation.
If you are running a rerelease in Japanese, it'll say "おす♂" if they're male and "めす♀" if they're female.
On the Spanish-language releases, it'll say "NIÑO" if they're a boy, and "NIÑA" if they're a girl.

On the original versions, you'll see the Gotchi points on the fifth page.

On European V2s, you'll be able to turn on a care mistake counter—that will appear on this page—by shorting the J8 component.

On the V3 and the rerelease, there will also be a page for the nickname you chose while setting up your device.
