ProUser turns a sentence into an event. Type "coffee with sam tomorrow at 9" and it's on your calendar — no menus, no date pickers, no taps. It reads plain language on-device, instantly. Say what and when, and the event lands. Same words, same result, every time — nothing waits on a server, nothing leaves your phone. Made for people who live in their calendar and think faster than they tap. WHAT YOU CAN DO • Add in one line — "dentist tuesday at 3pm", "lunch at noon", "gym friday 7am" • Let it find the time — "block 2 hours of deep work friday" takes your first free gap • Change things in plain words — push it later, move it, make it shorter, rename it • Clear a stretch — "clear friday afternoon" empties it in one step • Undo anything — every change reverses instantly; deletes ask first • Save your usuals — define "gym" once, then just type "gym fri" • Keep a todo list — "todo buy milk" adds it, "todo! call landlord" puts it first, "done buy milk" ticks it off • Your week on the lock screen — a Shortcut draws the week's events and your todos onto your wallpaper • Quick Add widget — open straight into the command bar from your lock screen • Type or speak it PRIVATE BY DESIGN Your calendar stays on your device. ProUser works offline, makes no account, and collects nothing. Edit your calendar like code.
