Wally and Betty’s Grain Gallery is an augmented reality journey that takes you from a wheat and barley farm all the way to your plate. During your journey, Wally Wheat will guide you as you drive a tractor during harvest to find out where the grain goes after a long summer of farming. You’ll crank a mill to see how wheat is ground up to make flour. Then you’ll take your freshly ground flour, make a pizza, toss it in the air and cook it in the oven! Once Wally has taught you all about wheat – one of Canada’s biggest and most well-known crops – you’ll meet up with Betty Barley for a whole new journey! Along with Betty, you’ll harvest barley in the field. Once you have barley seeds harvested and ready to go, you’ll go inside our cow friend’s stomachs to watch how those tiny, nutrient-packed seeds help it grow big and strong! But of course, cows need more than just one seed to grow big and healthy, so Betty will take you over to feed Charlie – our bovine buddy – several buckets of his beloved barley. Watch Charlie grow big and strong while he eats and see if he likes the barley! Don’t forget, farmers work hard to grow what we need to make some of our favourite foods like pizza, cookies, bread, muffins and pancakes. And with your help in Wally and Betty’s Grain Gallery, you’ll learn all about the important role they play in helping us grow big and strong… just like Charlie! Wally and Betty’s Grain Gallery is owned and operated by the Alberta Wheat and Barley Commissions. Together, the commissions represent 14,000 wheat and 11,000 barley farmers in Alberta. One of the commissions’ goals is to educate youth about where our comes from.

Verdict

The call

The clearest difference is in-app purchases: Grain Gallery AR at none against Hungry Hippo Attack Simulator's 6. Grain Gallery AR also leads on review sentiment (100% vs 86%) and update cadence (every 6 months vs every 13 months). Hungry Hippo Attack Simulator's advantage is rating (4.4 vs 4.0) and ratings volume (107 vs 2). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Hungry Hippo Attack Simulator holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Hungry Hippo Attack Simulator has 107 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 86% of Hungry Hippo Attack Simulator's written reviews are positive against 100% of Grain Gallery AR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hungry Hippo Attack Simulator ships an update every 13 months, Grain Gallery AR every 6 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
