Replay

What is Replay?

Replay is an iOS app for journey tracking that automatically saves your visits and routes. It maps places and movements across your day so you can relive trips and understand patterns over time.

The app focuses on lightweight, hands-off tracking and on-device processing, letting you review what happened (including travel segments) and attach your own context such as notes and photos.

Key Features

• Automatic visit and route saving: Replay records your locations and movements so you can revisit where you went without manually creating events.
• Day timeline with mapped activity: Your day is displayed with time blocks and travel segments (e.g., walking, driving) laid out clearly.
• Smart Activity Detection: It automatically detects modes of activity such as walking, cycling, and driving.
• Add context & memories: You can attach notes and photos to the items that matter to you.
• Pattern insights across days and months: It provides insights you can use to see recurring behavior over longer periods.
• Private by design (on-device storage and processing): The app states that no one else has access to your data, and all storage/processing stays on your device.
• No sign-up requirement: There are no accounts, emails, or passwords—download and start using the app.
• Battery efficient setup: The site describes it as battery efficient with a “setup once and forget about it” approach.

How to Use Replay

1. Download Replay on iOS and begin using it as part of your routine.
2. Let the app run to automatically save visits, routes, and detected activities.
3. Review your timeline for a recent day to see where you went and what type of activity occurred.
4. Add notes and photos to specific entries to document why a place or segment mattered.
5. Check insights to compare patterns across days, weeks, and months.

Use Cases

• Relive a trip or road trip: After a “working holiday” or weekend drive, review the timeline to see your route segments and how long each part of the journey took.
• Track commuting behavior: Compare morning drives or train/bus segments over time to understand how your commute varies by day.
• Document everyday travel without manual logging: For someone who is often on the road for work, let Replay automatically capture where they went while they focus on day-to-day tasks.
• Turn location history into a personal journal: Attach notes and photos to selected entries to preserve context beyond the raw map and timestamps.
• Look for longer-term patterns: Use insights across days, weeks, and months to spot recurring travel patterns rather than reviewing each day individually.

FAQ

• Does Replay require an account or sign-up? No. The site states there is no sign up: no accounts, emails, or passwords.

• Is my location data private? Replay describes itself as “private by design,” stating that no one has access to your data except you, and that storage and processing stays on your device.

• What does Replay track automatically? The site says it automatically saves your visits and routes, and that it uses Smart Activity Detection to detect activities such as walking, cycling, and driving.

• Can I add my own details to entries? Yes. The site mentions “Add Context & Memories,” including the ability to attach notes and photos.

• Does Replay show information beyond a single day? Yes. It includes insights across days, weeks, and months.

Alternatives

• Google Timeline (location history visualization): A similar category of timeline-based location history, but the site claims Replay is cleaner, simpler, and more enjoyable to use.
• Other travel/journey tracking apps (manual or semi-automatic logging): Instead of fully automatic visits and routes, some apps require more user input; workflows differ based on how much is logged automatically.
• Navigation and commute tracking tools: Tools focused on commute routes may emphasize trip planning or live guidance rather than reviewing past day-by-day patterns.
• Privacy-focused on-device tracking apps: Adjacent apps may also prioritize local processing; the key difference is whether they provide automatic timeline mapping plus activity detection like walking/cycling/driving.
