Calder Grove: Phone Mystery

A found-phone mystery

A phone from 2019 has come in as evidence. Read it, text the people who were there, and write down what happened that night.

For iPhone. If you joined the waitlist, you get the one message we promised and nothing else.

What it is

A phone that isn't yours, and an owner who isn't around to ask. Everything you learn, you learn off the screen: the threads, the camera roll, the notes. There is no narrator and nobody explains the rules.

How it plays

• Read the messages, photos and notes on a phone you found.
• Write back as yourself. People answer — and they don't all tell the truth.
• Timestamps are the puzzle. What was said, and when, is what gives someone away.
• Near-silent on purpose. Every sound is generated in the app, and there's a switch for it.

What it costs

Free. No ads, no in-app purchases, no subscription, no account. It runs on your iPhone and keeps your progress there.
