Someone is lying. The phone knows.
Redstring is a found-phone detective story. A client messages you in a live chat, hands you the victim's phone, and asks you to find the truth — from the first message to the final accusation. Every text, photo, voice memo, bank line and map ping is evidence. Read between the lines. Crack the passcodes. Pin the red string. Name the killer.
YOUR FIRST CASE IS FREE
Play "The Kessler File" from the opening message to the verdict — a full investigation, with no paywall in the middle of the story.
A LIVE CHAT WITH THE CLIENT
The person who knew the victim talks to you the whole way — asking the questions, reacting to your answers, and finally asking you to name a suspect. Type what you found; the story reacts.
SNOOP A FULLY SIMULATED PHONE
- Chats and DMs, including the deleted ones
- A gallery with Hidden and Recently Deleted albums
- Locked notes, voice memos, calendar, bank statements, browser tabs and location history
- Every app can hide a clue. Nothing is random.
PIN IT ON THE BOARD
Your evidence board pins each discovery and links it with red string. Leave for days, come back, and the case is exactly where you left it — progress is saved per case.
STUCK? ASK FOR A HINT
Up to three escalating hints per question nudge you toward the evidence without spoiling the answer. Smart answer-matching understands what you mean.
NAME THE TRUTH
The final question is an accusation. Get it right and the case closes; get it wrong and you can reconsider the suspects.

Redstring is a work of interactive fiction. All characters, phones, messages and events are fictional; any resemblance to real people or events is coincidental. The app never accesses your real messages, photos or data.
It's a very engaging game. The questions aren't as easy as in other games; you really have to work hard to find the answers. I liked the stories. The game is truly immersive. You rummage through the phone, collecting evidence and clues to answer questions. It's a very engaging game. I've finished it all and am eagerly awaiting the new cases.

Thank you so much for the amazing feedback! 🫶🏻 We’re thrilled that you enjoyed the stories, challenging questions, and the investigation experience. More cases are on the way, so stay tuned, detective! 🕵️♀️🔍
Good game but…
Idk who u r!
The game is fun and entertaining, but after you complete the first one, you have to pay for pro to do the rest of the investigations. If it wasn’t for that, I would 100% recommend it to anyone who likes investigating.
Developer Response
Thank you for the kind words, detective! 🫶🏻 We're really glad you enjoyed the first investigation. The first case is free from start to finish, and the Pass is what lets us keep building new ones. Every case is hand-made, with an original story, real evidence, custom photos and translations into 8 languages, and each one is tested continuously before it goes live. A new case lands every week, and the next file is already on the desk. Hope to see you back on the board! 🕵️♀️🔍
Not the best

I read the reviews and I thought it was going to be a really good app. I was doing the first case and really enjoyed it. They should really state somewhere that it costs money.
Developer Response
Thanks for playing, and we're sorry the pricing came as a surprise. 🫶🏻 The first case is free from start to finish, and in our App Store page, we clearly have information about that this app includes in-app purchases. Glad you enjoyed the first investigation, and a new case lands every week. 🔍

Gracias por tu comentario. 🫶🏻 El primer caso es totalmente gratuito, de principio a fin. Detrás de cada caso hay una historia original, sus pruebas, sus imágenes y traducción a 8 idiomas, y por eso publicamos un caso nuevo cada semana en lugar de soltarlos todos de golpe. El Pass es lo que nos permite seguir creándolos. Agradecemos mucho que lo hayas probado. 🔍
