Community Time Bank is a groundbreaking mobile application that reimagines skill-sharing within communities. Built on the principle of time-based currency, every hour of service holds equal value, fostering true equality and mutual support.
💡 The Concept
In traditional economies, not all skills are valued equally. Community Time Bank changes this paradigm:
1 Hour Teaching = 1 Time Credit
1 Hour Learning = 1 Time Credit
All skills are valued equally, whether it’s coding, cooking, yoga, or painting
🎯 Mission
To create inclusive communities where everyone has something valuable to offer and everyone can benefit from the collective knowledge and skills of others.
