Description
Bellweather: The Tuner is a free location-based mystery investigation game and alternate reality experience (ARG). Use the Tuner with your phone's camera and GPS to explore real-world places near you, find signal anomalies, walk around them to capture them in augmented reality (AR), and decode the evidence each one reveals. Read field updates from journalist Vera Liang inside the app, share findings in researcher discussions, and compare evidence with the global community of investigators.
About the investigation
Maren Calloway was tracking strange phenomena before she vanished from Linden Hollow, Ohio, on November 4, 1983. Forty-two years later, journals connected to her work were found hidden in the walls of her home on Bellweather Lane. The Bellweather Project is the public investigation into what she found, and what is happening now in the same places she once mapped.
What you do in the app
- Open the Tuner, walk to a nearby resonance point, and use your camera to find and capture the anomaly that appears there in AR - Decode the evidence each capture reveals: field notes, recordings, photographs, coordinates, transcripts, ciphers, puzzles, and other clues connected to Maren's research - Read Vera Liang's ongoing field updates, case files, and blog posts inside the app - Join researcher discussions, follow live field activity, and compare theories with other investigators - Some leads can be followed from home; others involve a short walk to a real-world location
About the gameplay style
Bellweather is an alternate reality investigation, so the line between in-app fiction and the real world is part of the experience. Some characters and records you encounter are part of the unfolding story. Some leads come from people who knew Maren. Some witnesses may not be telling the truth. Cross-reference the clues and evidence and decide for yourself.
Permissions
- Camera: required to detect anomalies and complete AR captures at resonance points - Location: required to find resonance points and Fundamentals near you, and to record where captures happen - Notifications (optional): used for nearby activity alerts and case updates
Free to play. Internet connection recommended.
Maren's disappearance is only the beginning. Follow the evidence, solve the mysteries, find the patterns, and take part as the Bellweather investigation unfolds.

Been having a lot of fun with this. The story of Maren is mysterious and intriguing, and I like that it gets you out exploring instead of just sitting at home doom scrolling. Definitely a different kind of thing...in a good way.

It's a great app, especially for mystery lovers. How you play it is you use you're camera to capture different anomalies around your own area and home, and gives you hints to the mystery. Meaning if you've been planning to go outside but too lazy, this app is a great to keep you active and actually have fun as you walk around to find anomalies

It's just a way to get your gps data to train AI on, barely disguised as an arg. Nothing more to it.
★☆☆☆☆Craig Hofmeister· Jun 15, 2026
Probably fin for people motivated to waste their free time chasing down a fake crime as if chasing down fake Pokémon. Spent all of 10 seconds on this game before I said eff this ish and deleted it. If It's for you by all means enjoy but im not getting hit by a car playing fake detective!

Uses Gen AI slop and comes from an AI company. If the creators are really passionate about the story, then they can use real photos edited by hand or human-made art. Talk about a disappointment.
★☆☆☆☆Keith Swinton· Jun 27, 2026
It doesn't even work? You find "an anomaly", it tells you to walk around it, and the blue blob just gets stuck in the corner of the screen. Complete waste of time, and I look incredibly stupid just pacing in circles
