Your to-do list just leveled up. Literally. Tired of to-do apps that reward you with... nothing? NinjaDo turns every checked-off task into a real mission for your very own ninja. Add a task. Complete it. Watch your ninja sprint off into a pixel-art world to finish the job for real — mining crystals, rescuing runaway cats, sneaking through hidden dungeons, and taking down roaming "quirks" along the way. Finish the mission, earn gold. Skip laundry day, and... well, your ninja's still there waiting, shuriken in hand. Why NinjaDo hits different: Every task spawns a unique mini-mission in a living overworld — no two days look the same. Tap to move, dodge into Rapid Fire mode, or line up the perfect shot on the 8-directional aim grid. Explore hidden dungeons with statue puzzles, locked chests, and NPCs who have opinions about your productivity. Earn gold from every mission and every enemy you clear, then spend it in the Skill Store on 10 upgradeable weapons — from a humble starting shuriken all the way up to a Metal Ball that hits like, well, a metal ball. Don't worry about dying mid-errand: your ninja can dish it out but never takes damage, so the only real risk is procrastinating. Getting things done has never felt this much like getting away with something. Stop managing tasks. Start sending a ninja to handle them.
