If you’re someone who keeps sticky notes on your desk, leaves packages near the door so you’ll remember to return them, or lets chores pile up until they blend into the background, this app makes those reminders impossible to ignore. Just snap a photo of the visual cue, name the task, and set a deadline. Sticky Tasks tracks the countdown, tells you when the deadline is coming up, and notifies you the moment you miss it. When you finish the task, take a completion photo to mark it done. No complicated systems. No endless to-do lists. Sticky Tasks works with the way you already remember things - your physical environment. How it works: - Photo your visual cue (sticky note, object, package, mess, anything). - Set a deadline you actually intend to hit. - Watch the countdown so the task doesn’t fade away. - Get notified before and after the deadline. - Finish the task and snap a completion photo for accountability. Perfect for: - People who rely on visual cues to remember tasks - Anyone who loses track of chores, returns, paperwork, or small obligations - People who want a simple tool that actually helps them follow through Turn your environment into an accountability system. Stop forgetting the things that matter.
