Add variety to your quizzes with 'Quiz Blob'. Get everyone to install the free version that comes with an outline map of the British Isles. Can people mark where London is with a red blob? OK - easy enough - but what about other important cities such as Glasgow? A blue blob for Edinburgh? A purple blob for Birmingham? A light blue blob for Cardiff? And, of course, a green blob for Dublin!

In the end, there's only so much you can ask about the British Isles. Then it's time to upgrade, and then you can let your imagination run wild. You decide which image you'd like to use. It could be a map, a diagram, an old family photo, a photo of your vegetable patch, even a selection of breeds of dog. Use your ordinary email to send it to all your contestants, so it ends up in the camera roll on their device. It's then available for them to use. Upgrading is at the lowest possible price tier so everyone can afford it.

Blobbed pictures can even be saved to the camera roll, so people can immediately email them back to you. Not only can the results be shared, but this gives you the chance to ask "nearest to" questions. Who has put their blob nearest to the position of Mount Everest?

Contestants can use their phone to take a photo for your quiz. You could ask people to photograph and put blobs on the things in their own wardrobe, sock drawer or fridge!

Why not give it a go? There's nothing to lose, and it will help brighten up everyone's day. We made this app for our own family quiz, and each week someone thinks of a new use for it, and it's always funny!

You won't be troubled by any ads, and you don't need to sign-in to use the app. No data is collected. What's in your freezer remains your secret - only you and now, of course, all of your family will ever know what's in there!
