About

Doubtfolio

Features
Read full description

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/
