The To-Do List Trick That Actually Gets You to the Grocery Store

A hands-on look at Planner: To Do List & Reminder, the to-do list app that uses location-based alerts to nudge you exactly when and where a task actually needs doing.

The To-Do List Trick That Actually Gets You to the Grocery Store

About this app

The problem with most to-do lists isn't writing the task down — it's that buy milk sits on a list you never open until you're already home and the store is closed. A reminder that fires at 9am does nothing if you're not near a shop until 6pm.

What This Planner Is Actually Trying To Solve

This is a fairly standard task and reminder app on the surface — add a task, set a time, get notified — but the part that separates it from a plain notes app is location-based alerts. Instead of just picking a time, you can tie a reminder to a place, so picking up dry cleaning pings you when you're actually near the dry cleaner, not at some arbitrary hour when you're stuck in a meeting.

Where the Actual Value Is

  • Reminders tied to a place, not just a clock: set an alert for when you arrive somewhere or leave somewhere, which is genuinely more useful for errands than time-based pings.
  • Checklists inside a single task: break a big task into ten smaller steps instead of ten separate to-dos cluttering the main list.
  • Color-coding by category: glance at the day and know instantly what's work, what's personal, and what's urgent, without reading a single word.
  • Custom ringtone and vibration per reminder: make the ones that matter impossible to sleep through and let the low-priority ones stay quiet.
  • Fast task entry: add something in a few taps before you forget it, which matters more than any other feature if you're the type who thinks of things at inconvenient times.

A Few Honest Notes

It's a smaller app — around 10K downloads and a 3.7 rating at last count — which usually means it does the basics solidly without the polish of the bigger productivity names. It's free with ads and optional in-app purchases, and it's rated for all ages, so there's nothing here beyond straightforward task management. If you need calendar sync or team collaboration, this isn't built for that; it's a personal planner, not a project management tool.

Most people don't fail at productivity because they lack a place to write tasks down — they fail because the reminder shows up at the wrong moment. A to-do list that can also pay attention to where you are is a small change that fixes a surprisingly big chunk of that problem.
