Meet Tolva and Ting. Tolva’s a super computer in charge of a team of “Globots” robots, tasked with collecting ingredients for Tolva to turn into ‘Juice’. Ting is the cleverest of them all.

The pair are stars of a series of new children’s apps from developer Me and the Giants under the banner, with five released for iPhone and iPad this week.

They blend education elements like shape and colour recognition and motor skills with an exploration of different moods and how they affect children and grown-ups alike, by showing how tiredness, anger, greed, silliness and other moods affect the Globots.

Tolva and Ting Guide may be the best place to start: it’s a guide to the characters and their world, explaining their good and bad moods. It’s a free download for iPhone and iPad.

Tolva and Ting Moods continues the story, using the Globots to cheer up moody friends by testing different emotions. Me and the Giants describes it as a bit like “Rock, Paper, Scissors with moods” in that respect. It costs £1.99 for iPhone and iPad.

Tolva and Ting Count Me is a bubble-popping game that gets kids started with maths: addition, subtraction, quantity, sequence and the concept of zero. It’s a free download for iPhone and iPad.

Tolva’s Ting Toy focuses more on writing and touchscreen gestures, getting kids to make Ting “dance, back flip, head spin and fly” with the appropriate gestures. It’s free for iPhone and iPad.

Tolva’s Shapes, finally, is all about music and colour matching, with children dragging shapes into the right holds on-screen, getting robots to do different dances for each shape (“disco, rock, drum and bass and dub reggae”). It costs £0.69 for iPhone and iPad.

So, less than three quid for the lot, with three of them free to play with no in-app purchases so your children can get to know Ting and Tolva. Give them a try and let us know what you think!
