Steal Alert

Steal Alert is a mobile application where you can find the best deals in fashion and electronics. The app is available for free on Google Play and App Store.



The challenge

NS Code partnered with Steal Alert to develop the cross-platform app from scratch. Since Steal Alert was a startup with limited initial budget, we had to strictly adhere to the budget frames. The app functions as a marketplace for promotions of clothing, technology, and various other goods, selected either by users or app administrators.


The project required the involvement of four people: React Native Developer, Frontend Developer, Product Designer and Project Manager


Steal Alert has 300 000 monthly active users.
No. 1 free app in Polish App Store in 2018.
