VoyVoy is a small side project I built because I wanted a simple, free currency converter while traveling — without ads, subscriptions, or tracking.
It lets you convert currencies instantly, works offline with cached rates, includes a lock-screen widget for quick checks, and even generates reference wallpapers with common amounts (10 / 20 / 50 / 100).
