Downloading free Apps to your smartphone or tablet could end up costing you more than nothing.  The popular ‘freemium’ business model for apps mean that while the original app is free, small in-App purchases that unlock features, add-ons or levels could get quite expensive.

Most people come undone with in-app purchases when handing over their device to a child…who if given full access could quickly add $50 or more in micro transactions to your credit card in one sitting.

The solution is simple, either disable in-app purchase within your device or lock them down with a password that you don’t share with anyone.

For iPhone and iPad users here’s a guide to disabling in-app purchases.

For Android device users you’ll find a ‘how to’ guide here.
