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.

Verdict
The clearest difference is ads: Cold Case Trace at none against Stalkie · Mobile Detective's shown. Cold Case Trace also leads on review sentiment (29% vs 16%). Stalkie · Mobile Detective's advantage is ratings volume (2.9K vs 68) and iOS requirement (13.0 vs 18.0). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Stalkie · Mobile Detective sells 5 in-app purchases, starting at $5.99 per 7 days and Cold Case Trace sells 7 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Stalkie · Mobile Detective holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Stalkie · Mobile Detective has 2.9K ratings behind it against 68, so its average is the more settled of the two. Written reviews complicate that: 16% of Stalkie · Mobile Detective's written reviews are positive against 29% of Cold Case Trace's, so the app with the better star average is not the one people write more warmly about.
Stalkie · Mobile Detective ships an update weekly, Cold Case Trace every 9 days. The most recent releases landed on November 8, 2026 and November 10, 2026 respectively.
