The iOS app "C2 Flanker Task" records the response time of a flanker task (task conflict) in milliseconds. Response time is the time from when the task is displayed to when the answer button is touched (touchdown). The recorded data can be output to a CSV file and read into a spreadsheet application such as Excel. In addition to the orthodox flanker task, you can also check the effect by changing the presence or absence of coloring, the brightness of the background, the shape of the arrow, and so on. * The effect of the flanker task appears, for example, as the difference between the time to recognize the direction of the central arrow of →→→→→ and the time to recognize the direction of the central arrow of ←← → ←←.

Passpack brings 20 years of trusted password management to iPhone. Store, organize, and share passwords with end-to-end encryption that means only you can read your data — not us, not anyone else. ZERO-KNOWLEDGE BY DESIGN Every password, note, and credential is encrypted on your device before it ever leaves your phone. Passpack uses a layered AES-GCM + RSA-OAEP key hierarchy so the data sitting on our servers is unreadable without your packing key. We can't decrypt it. Our engineers can't decrypt it. An attacker who breaches our infrastructure can't decrypt it. That's the point. KEY FEATURES • Encrypted password vaults — store logins, secure notes, and custom fields with AES-256 encryption. • Built-in 2FA / TOTP — generate time-based one-time codes alongside the credentials they protect. • Team sharing — share specific passwords with specific teammates via a per-team key system. Revoke access at any time. • Vaults and tags — organize by department, project, client, or any structure. Color-coded tags make search fast. • Cross-device sync — use Passpack on iPhone, iPad, the web app, and the browser extension. Your data follows you. • Single sign-on — log in with email, Google, or Microsoft (Azure). Full MFA / TOTP support. • Device approval — new device login attempts must be approved from a trusted device. Even with your password, an attacker can't get in. BUILT FOR TEAMS — NOT JUST INDIVIDUALS Most password managers treat sharing as an afterthought bolted onto a personal-vault product. Passpack was built around shared credentials from day one. Vaults, teams, and role-based permissions are first-class concepts, not features grafted on later. Whether you're a two-person consultancy or a multi-department company, the same architecture scales without compromising on encryption. PRIVACY AND SECURITY The iOS app uses iOS Keychain to store device-level keys and standard, well-vetted cryptographic algorithms — AES-GCM, RSA-OAEP, PBKDF2, SHA-256. The app is classified under EAR ECCN 5D992.c (mass-market encryption software). Because of zero-knowledge encryption, your packing key is the only way back into your account. Passpack staff cannot reset it for you. We strongly recommend storing it somewhere safe — a recovery sheet, a hardware vault, or a trusted family member. REQUIRES A PASSPACK ACCOUNT New to Passpack?
