An iOS app that can be built and installed on your mom's phone. Every day it will have a new reason why you love her. All you need to do is customize a JSON file and hit Build.
I made this pretty quickly one day and my mom loved it. I hope I can help you guys make a memorable Mother's Day for your moms! Minimal effort (just customize a single file) and give your mom a year of love with an app that only can be installed on her phone.
