VuelvaTech is an independent studio crafting practical Android apps, browser-based games, and wellness tools — all built offline-first, privacy-first, and free to use.
Each project built from scratch — no shortcuts, no bloat, just focused tools designed for real people.
A free, fully offline Android bill and budget manager. Track recurring bills, manage budgets, monitor accounts, and visualize your 6-month cash flow — no account, no cloud, no fees.
6 wild mini-games, up to 10 players, local and internet multiplayer — all in a single 500KB HTML file. No frameworks, no install required. Just share a link and start playing.
A gentle, fun memory card game designed to help older adults keep their short-term memory sharp. 300 stages across three difficulty levels, 5 card themes, and fully synthesised audio — all offline.
VuelvaTech is an independent software studio. Every product — from the bill tracker to the party game to the memory app — is designed, coded, and maintained with no outside investors.
The philosophy is simple: build things that are genuinely useful, keep them free, respect users' privacy by working offline-first, and never add a login screen unless it's absolutely necessary.
Bug reports, feature suggestions, collaboration ideas — all messages are read and appreciated. Your feedback directly shapes what gets built next.
