Not a bad start
However, there are a couple of improvements that could be made.
When first installed the app immediately asks for a password via a modal prompt. I assume this is to log in to the schools forum. However I have yet to receive or find reference to this password on the schools website or in any correspondence currently received from the school. So at present you have to select cancel to get any further into the app.
When booking and paying for dinners, snacks and after school care, you have to book each separately. This means repeating the same details for your child, email and class and separate payments to paypal as well. It would be much more efficient and faster to make all your bookings and then make a single grand total payment.
Hopefully these suggestions can be taken onboard in future updates.
