The paper fits
the phone.

A PDF turns an iPhone into a viewport: pinch, pan, lose the line, repeat. FirstPass lays out the paper for the screen, then opens references, figures, tables, and equations over the passage that called them out.Start with the paper you already have. Links from Safari and other apps can open directly in FirstPass.

a full read.

FirstPass covers the entire arXiv archive and updates daily. Use as much or as little of its discovery system as you need: scan a Feed, search the archive, or monitor a field.

Your reading life
is not an account.

FirstPass does not require an account. Your Library, reading state, highlights, notes, and preferences are stored on your device. Some features make requests to FirstPass services, iCloud sync is optional, and product analytics stay off until you enable them.

On your device

Your Library, likes, reading state, highlights, notes, preferences, cached files, and generated Briefs. Feed ranking, Brief generation, and Library matching also run locally.

FirstPass services

Search, Feed, recommendation, citation, Radar, Smart Folder, and model-download requests may reach FirstPass services. Some paper identifiers and highlighted passages are briefly sent to create embeddings used for ranking and matching on your device. They are not retained as part of a persistent account or research profile. Note text is not sent to FirstPass services.

Your iCloud, if enabled

When enabled, supported Library data, highlights, notes, and reading state sync through your iCloud account.

Analytics, off until enabled

When enabled, analytics record limited feature usage. They never include paper identities or content, search terms, highlighted passages, note text, URLs, location, purchase data, or a persistent user or device identifier.
