## Cold Case Trace Description
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.

10 CASES AT LAUNCH — MORE ON THE WAY
Murder, disappearance, blackmail and betrayal across Europe — Paris, Berlin, Lisbon, Vienna, Amsterdam, Prague, Copenhagen and Barcelona. Fully playable in 8 languages.

REDSTRING PASS
Case 1 is free forever. The Redstring Pass unlocks every case:
- Weekly: $4.99 per week
- Annual: $29.99 per year
- Lifetime: $39.99 one-time — not a subscription

## Cold Case Trace Reviews in United States

### **--- "Needs work"
I only did the first free case so my review is limited. But first impressions led me to turn down paying for the full version of the app. On the positive side, I liked how you could pin clues to the board. The phone apps for browsing were laid out well. But I found the questions to be worded in a confusing manner and once you entered the correct answer, the next part of the story flashed on and off the screen so quickly, you had no time to read it fully before the next question popped up. So the whole time I was playing, I barely had a grasp of the storyline or what was going on. Even so, like most games in this genre, the suspect became obvious very quickly and it was just a matter of trying to answer the questions correctly, which wasn't always the easiest thing to do. For instance, if asked for a time that a certain event happened, "2:00 pm" will be rejected but "2:00" will be accepted. Oftentimes, it's just trial and error trying to figure out the wording that will be accepted to move on. For these reasons, I've decided it's not worth paying the $20 for more cases so I'll be deleting the app.

### ***-- "Good game but…"
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.

### *---- "."
Debe ser gratis todos los casos
-- Casos sin resolver, 2026-09-08

### **--- "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.
-- Bluey lover742, 2026-09-07

### ***** "Fun Game"
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.
