How we chose these tools
Every tool here was used on real work, not just demoed. These are the criteria we weighted, in order.
Due exists for one reason: making sure you never forget. Its auto-snooze re-nags you every minute (or interval you choose) until you actually act, so a reminder can't quietly scroll off your lock screen. Fast natural-language entry and repeating timers make it the gold standard for things you genuinely cannot miss.
Nothing else is as persistent. For medication, bills and pick-ups, Due's relentless re-alerts are the feature every other app is missing.
Apple Reminders has quietly become genuinely good. Time and location-based alerts, smart lists, tagging, natural-language input and the killer 'remind me when messaging' feature — all free and synced across every Apple device. For most iPhone users it's all the reminder app they need.
It's free, built-in, and now powerful enough that most people never need to install anything else. Location reminders are best-in-class.
Todoist turns typed sentences like 'pay rent every 1st at 9am' into scheduled, recurring reminders instantly. Cross-platform, reliable and fast, it's the best choice if you want reminders that live alongside a proper task system rather than in a standalone nag app.
The best natural-language parsing in the business, and reminders sync flawlessly across every platform — the cross-platform pick.
TickTick pairs flexible reminders with habits, a Pomodoro timer and a calendar view. Its 'annoying alert' mode rings persistently like an alarm until you respond — a rare and welcome feature on Android, where most reminder apps fall short.
The best all-round reminder app for Android, with persistent alarm-style alerts plus habits and focus tools in one place.
Microsoft To Do is a clean, free reminder and task app that syncs with Outlook and Microsoft 365. Set one-time or recurring reminders, get a daily 'My Day' planning prompt, and have everything appear next to your Outlook tasks automatically.
The best free cross-platform reminder app for anyone in the Microsoft or Outlook ecosystem — no cost, no catch.
Google Keep is the fastest way to jot a note and attach a reminder. Time and location-based alerts, voice capture, and instant sync with your Google account make it ideal for quick, lightweight reminders without the overhead of a task manager.
The best free pick for Android and Google users who want frictionless capture-and-remind without learning a new app.
A veteran for good reason, Remember The Milk sends reminders through every channel you can think of — push, email, SMS, even via your smart assistant. Smart Lists and tags give power users fine-grained control over what surfaces when.
Unmatched for multi-channel reminders. If you want a nudge by email and SMS as well as push, nothing else covers as many bases.
Memorigi is one of the best-looking task and reminder apps on Android, with gorgeous design, recurring reminders, subtasks and a daily planning view. For Android users who find Google's options too plain, it's a delightful, fast upgrade.
The design-forward Android pick that's gaining traction — proof a reminder app can be both reliable and genuinely pleasant to use.
