While many apps are free, sometimes you may also decide to pay for apps, which commonly cost around 99p to £2.99, (though some can cost more). In-app purchases are not always obvious; you may have downloaded a free game app, but then to upgrade to the next level you are asked to make an “in-app purchase”. By doing this you will be asked to pay an additional sum of money, we have heard stories where young people have got into difficultly and have ended up running up huge bills!
You can turn off in-app purchases if you are worried and on some smartphones it is possible to block in-app purchases and downloading apps by going into your phone settings.
