What Are Milestone Capsules, and Why Do They Matter?
Want to preserve memories that unlock on special dates every year? Learn how to create a Milestone Capsule in TimeLock, with step-by-step images.
In a world where memories can disappear with a swipe, TimeLock offers something powerful: a way to preserve moments that truly matter. Whether it’s your child’s first birthday, your yearly anniversary trip, or a tradition with your best mates, Milestone Capsules let you lock in these memories and relive them again and again.
Unlike one-time capsules that unlock once and disappear, Milestone Capsules in TimeLock are recurring. You decide the schedule: annually, monthly, or even custom. They’re perfect for moments that deserve to be remembered, not just once, but every year.
Here’s your complete step-by-step guide to creating a Milestone Capsule using TimeLock.
Step 1: Tap the Button to Create a Time Capsule
From your TimeLock home screen, tap the capsule icon at the bottom center. This is your gateway to creating all types of capsules, including Milestone ones.

Step 2: Choose “Milestone Capsule”
You’ll now be asked what type of time capsule you want to create. Select the Milestone Capsule option, this allows your capsule to unlock repeatedly based on the frequency you define (daily, monthly, yearly, or even a custom rule).

Note: Milestone Capsules are available to Premium users.
Step 3: Choose Capsule Mode (Personal or Collaborative)
Do you want this capsule to be just for you, or would you like to invite others to contribute?
- Personal: Only you can add memories.
- Collaborative (Premium): Perfect for shared memory-making. For example:
- A group of friends saving annual festival memories
- A family adding yearly birthday messages for grandma
- A couple logging relationship milestones
Select your preferred mode and tap Next.

Step 4: Choose a Category (Or Upload Your Own)
You can now pick a category for your capsule, like:
- Birthday
- Marriage
- Holiday
- Love
- Gym
- Books …and more.
Or, upload your own photo to personalise it further.
Choosing a category not only makes your capsule easier to organise, it also determines the theme and mood of your capsule’s background visuals.

Step 5: Customise the Background
Next, you’ll see a themed background. You can:
- Keep it as-is (based on your category)
- Use the palette icon (top right) to explore other visuals
- Tap “Add to capsule” when you’re happy with the background
This personalisation step adds emotional context to your memory. Visuals matter, and TimeLock makes sure they match the moment.

Step 6: Set Your Milestone Unlock Date
Now it’s time to lock in the moment. Under “Recurrence Setup”, choose:
- A title for your capsule (e.g. “Anniversary Capsule”, “Birthday Reflections”)
- The recurrence type (e.g. weekly, monthly, yearly, etc.)
- The unlock date (e.g. every 5th September)
- The unlock time (optional but great for birthday capsules)
For recurring schedules:
- You’ll be able to set how often this capsule unlocks (e.g. once a year, every month, or a fully custom setup)
This is where the magic happens; your memory becomes ritual.

Step 7: Finalise & Create Capsule
Once you’re happy with everything, tap “Create Milestone”
That’s it. You’ve just made a living memory, one that revisits you every year, like a letter from your past self.
