What's New in Grass

2.2

November 9, 2026

• iPhone Duo. The field fills the inner display and keeps its state across folds, unfolds and rotations. Half-shut the phone and flap it to fan a gust. The pacer and cards sit clear of the crease. • Landscape and Split View on iPhone and iPad; compass and breath winds stay anchored to the room as you rotate. • Apple Pencil combs with a finer tip.

Update this Glorious App

I’m really sad that this app doesn’t work anymore. It was my first ever app download when I got my first smartphone. It has sentimental value and I can’t bring myself to delete it. Whoever created this app needs to update it so that it works again!

Somehow great

My son, who has access to a variety of apps, always falls back on this one as a top three.
Sometimes simplicity is just what the doctor ordered.
Wish the developers would update this to work on the new software.

In a world of white supremacist and evil I found grass

Ok may I say that this is... LIFE CHANGING. I owe my life to this app. I wake up for this app. It brings you to a state of happiness that can only be described at nirvana. At the end of a bad I draw myself a bath and play grass for hours until I fall asleep. Please join me in enlightenment by getting this app.

I've never played a more intense game!!

This is an amazing app! I gave up call of duty to play endless hours of grass!! This game is also very competitive. Me and my friends have weekly battles on grass. Grass makes me feel good about my self.

Great app!!!!!!!!!!

Great RPG! I love this and I can't stop playing it. I would play this all the time if I could! My only complaint is there is too much profanity and it's not appropriate for the kids
