A message sounds convincing. A photo raises questions. Doubtfolio gives you a local notebook to work through claims you are unsure about. KEEP A CASE TOGETHER Write down the claim and where it came from. Add evidence for and against it. For a photo or message, mark the warning signs you notice yourself. Work through an eight-point contradiction checklist, then journal how convinced you are over time. YOUR NOTES, YOUR JUDGMENT The app counts and remembers what you record. It does not detect warning signs, verify content or decide what is true for you. Any count comes from your entries, not an independent assessment. STORED ON THIS DEVICE Your case content stays on this device, except for exports you choose to share and data included in operating system backups. OPTIONAL IN-APP PURCHASES โ€ข Premium Share Card: one credit to export a premium summary card for one case. This is a one-time purchase. An earlier subscription may still renew separately. A one-time purchase does not cancel it. Review or cancel it in your store account's subscription settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Smart DVR connection

Features
Read full description

The Smart DVR mobile app is your personal video surveillance remote control, turning your smartphone into a fully featured monitoring and configuration center. It is designed for instant connection to a wide range of dashcams and hybrid devices through their built-in Wi-Fi modules, with no extra cables, adapters, or complicated network setup. The intuitive interface gives you full control over video recording in real time: start manual or emergency recording, activate motion detection, and quickly adjust microphone sensitivity and exposure settings. The built-in player lets you play saved files without delay, while fast export allows you to download the clips you need directly to your device's photo library in seconds. There is no need to remove the memory card or connect the dashcam to a computer. Camera settings are especially flexible: adjust video resolution, frame rate, bitrate, white balance, contrast, and saturation to suit any lighting conditions, from bright sunshine to deep twilight. Changes take effect immediately and are saved in the device's memory, making it easy to get the recording quality you need. Smart DVR also includes convenient file management: sort recordings by date, time, and event type, protect important footage from accidental overwriting, and use batch downloading to save data and time when transferring large amounts of footage. Supported devices: - KARADAR SRECORDER R102
