When you provide your mobile number to the app, it searches your schools database to determine if your mobile number is on our record. If the app is unable to find your number, then please contact your school to ensure your mobile number has been correctly assigned to your child at that the school has it on record. It may be that the school has several numbers for your child, usually one for each parent, and they only have one number against your child in their SchoolMoney system.
You can find the app by clicking on the respective icon for your mobile Operating System :
Unfortunately SchoolMoney support cannot help you gain access to the system and you must go through the school.
