A found-phone mystery for iPhone where the entire interface is a recovered phone from 2019

LOS ANGELES — September 29, 2026 — SDV Signal today released Calder Grove, a free found-phone mystery for iPhone, on the App Store.

In Calder Grove, players take the role of a records clerk at a law firm. A phone from 2019 has come in as evidence: texts, photos, notes, a call log, and a recording. Most of it was recovered. Some of it wasn’t. The assignment is two pages on what happened the night of April 13.

Gameplay is exploring that phone as evidence. Players scroll messages and the camera roll the way they would on any phone, fill in a memo one blank at a time—learning only how many answers are wrong, never which—and may text people who were there. Those contacts are adults now. Some will talk. One will block the player. Replies arrive in real time over minutes or hours, so progress continues when the player puts the phone down and comes back.

Calder Grove is free, with no ads. It is rated 12+ and listed under Games — Puzzle and Adventure. The app is available now for iPhone.
