Frankley School in New Plymouth has produced three apps that have potential to go global.

A brand new app has been designed to combat bullying - and it's been created by five primary school girls.

The year six students at Frankley School in New Plymouth worked together to try to combat the rising figures of bullying in New Zealand for 7 to 14 year olds.

The app educates bullies and the bullied about the different types of bullying and what they can do to stop it - it also has a feature that reads the words on the screen to the user in case they can't read it.

GRANT MATTHEW/STUFF Frankley School, New Plymouth students (back) Eva Lea 10, Emily Goodeve 10, (front) Daina Thorpe 11, Ashley Lewis 11 and Aimee Neilson are in the top three for a tech competition.

Games in the app are used to calm anxious minds and that's something their classmates love the most.

Eva Lea, Emily Goodeve, Daina Thorpe, Aimee Neilson and Ashley Lewis, entered their app in the Tech Girls' Movement competition which aims find the next tech girl superhero.

The 10 and 11-year-olds spent 12-14 weeks researching, designing, coding and business planning to create the app.

Thorpe coded every day for one month to get the app up and running.

The app was created for the competition only and is not available to the public.

Five teams from Frankley School entered in the competition.

Two teams received an award and three teams were announced as the top three apps in New Zealand out of 170 schools in New Zealand and Australia.

Teacher Brendon Anderson said he was stoked that all five teams entered were recognised for their hard work.

"The ideas, the problem solving the thinking comes from them," he said.

The other teams were Creative Coderz, who created a 'fishing siri' which is a hands-free way for fishermen to get information about legal sizes and catch limits, and Crazy Coderz, who created an app called My Safety Toolkit that gives safety information about the mountain, bush and river.

Anderson says the world is now their oyster and they have the opportunity to decide if they want to take their apps further.

"The fishing app, they actually want to consult with someone now about what they would need to do to get it professionally made because the apps have so much potential," he said.

The New Zealand winners, which will be from Frankley School, will be invited to submit their app to a global teach challenge, with the global winner getting a free trip to Silicon Valley, San Francisco to pitch their app.
