ABOUT

IṢIRO /Brain Snacks is a solo developer's love letter to lifelong learning. No social feeds, no distractions—just you, timeless wisdom, and a moment of focused growth.

The name IṢIRO (pronounced "ee-SHEE-roh") comes from the Yoruba word for "calculation / Solve." — honoring a language deeply rooted in wisdom and strategic thinking. This daily practice channels that same intentionality.
