Pebs have a life of their own.
A few things that happen whether or not you’re watching.
Projects
Pebs choose their own multi-day projects based on their personality and world. You don’t assign them.
Peb Moments
Occasionally your Peb creates a small memorable moment just for you.
Favors
Sometimes your Peb quietly hopes you’ll notice what it wants. You might even make its day without realizing it.
Adventures & Memories
Pebs explore, remember experiences and change over time.
The world matters
Time, weather and other parts of the world around your Peb can affect what happens.
Latest Pebological Findings
Pebs write postcards, undertake suspiciously ambitious projects, occasionally want snacks and apparently make friends. Research continues.
Pebworld is not a game you win. It is a quiet little place you return to. Your Peb reacts to your visits, learns small preferences, asks gentle questions, and creates tiny rituals over time.
No two Pebs grow exactly the same. Every Peb slowly develops its own habits, voice, favorite objects, rituals, and way of exploring.
Tiny Adventures
Your Peb can wander, discover objects, and sometimes come home early because it found something important.
Memories & Rituals
Pebs remember little moments, repeated habits, favorite things, and shared routines.
Different Peb Personalities
Some Pebs become chatty. Some stay quiet. Some get dramatic about leaves.
Pebworld Atmosphere
Every day has its own soft atmosphere, from crisp mornings to sleepy evenings.
Little Peb Projects
Pebs invent projects all on their own — building something, collecting treasures, practicing a skill, or quietly working on a surprise.
A Peb That Notices
Pebs are surprisingly aware of the world around them. Try gently tilting your phone — you might discover something just beyond the edge of the world.
Speaks Your Language
Pebworld is available in English, French, Spanish, and Japanese — which the Pebs are still practicing.
Apple Watch Companion
Check in with your Peb from your wrist.
Private by Design
Pebworld does not need accounts, ads, or external AI services.
Questions?
How much does Pebworld cost?
Pebworld is free. No subscriptions, no ads, and no in-app purchases.
What are Postcards?
New in Pebworld 2.0: exchange a Peb address with a friend and your Peb can send their Peb a tiny postcard and trinket. Pebs can reply, remember their new friends, and stay in touch.
Is Pebworld a virtual pet?
Sort of, but softer. Pebworld is more about memories, rituals, and personality than meters and chores.
Can my Peb die?
No. Pebs can get sleepy, curious, hungry, or low-energy, but they never die.
Does Pebworld use AI?
Pebworld may use on-device Apple language features when available to vary short Peb dialogue. The app is not an open chatbot.
Does Pebworld require an account?
No account is required. iCloud may be used to sync your Peb across Apple devices.
Is Pebworld for kids?
Pebworld is family-friendly, but it is designed for anyone who likes cozy, quiet, whimsical apps.
Do Pebs all act the same?
No. Pebs develop differently based on memories, rituals, adventures, favorite objects, and communication style.
Can Pebs start interactions?
Yes. Pebs may occasionally ask questions, suggest tiny rituals, mention discoveries, or decide they want to wander.
Are adventures just timers?
No. Pebs choose hidden little objectives and may return early when the adventure feels complete.
Does Pebworld have holidays?
Yes. Pebworld has its own small fictional holidays that appear throughout the year.
