Save photos to document your pet's growth from puppy/kittenhood to adulthood and capture every adorable moment. Receive tailored advice on feeding, grooming, exercise, and coat care based on your pet's breed, age, and size. Log important events—such as vaccinations, deworming, baths, nail trimming, and check-ups—to ensure nothing is overlooked. Ideal for: Those curious about their cat or dog's breed. Owners wanting to learn more about their pet's personality, size, and lifespan. People who want to document their pet's growth photos and health records. Owners seeking convenient reminders for daily pet care routines. Pet enthusiasts who love cats, dogs, and all furry companions. PetMate AI goes beyond simple identification; it is an AI assistant that supports you in providing excellent long-term care for your pet. Note: Identification results are for reference only; inaccuracies may occur with mixed breeds or unclear photos. Health-related advice is not a substitute for professional veterinary diagnosis; please consult a veterinarian if your pet shows any signs of illness or abnormality. Privacy and Data Security PetMate AI stores your pet profiles, identification records, growth logs, and reminder data locally on your phone by default; this information is not automatically uploaded to the cloud. You retain full control over your pet's photos and records, ensuring greater peace of mind during daily use. Important Note The current version does not yet support cloud synchronization or account backups. Data stored locally within the app may be lost if you switch phones, uninstall the app, or clear the app's data. We recommend saving important photos to your phone's photo gallery; future updates will gradually introduce support for iCloud, Google Drive, and account-based cloud synchronization.

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.
