PGPony vs FlowCrypt.

Both are modern OpenPGP apps with iOS and Android clients. FlowCrypt is Gmail-centric and built for enterprise deployment as well as individuals. PGPony is channel-agnostic and built for individuals. The mobile UX and tradeoffs differ significantly.

// the short version

You live in Gmail and want PGP that talks directly to your inbox? FlowCrypt. You want PGP that works the same in any channel (email, files, paste sites, SMS) regardless of email provider? PGPony.

Honest tradeoffs.

Where FlowCrypt wins

  • Direct Gmail integration. FlowCrypt connects to Gmail through Google\'s API and presents your encrypted inbox inline, with decryption happening in-app. If your entire workflow is Gmail, this is a noticeably smoother experience than PGPony\'s "copy to PGPony, decrypt, copy back" loop.
  • Enterprise-ready. FlowCrypt sells to organizations with central admin, key escrow options, and Google Workspace Client-Side Encryption integration. PGPony has no enterprise product.
  • Established and funded. FlowCrypt a.s. is a real company with paid customers and dedicated security review. PGPony is a solo indie developer\'s side project — fewer resources, but also no vendor risk in the corporate sense.
  • Bug bounty program. FlowCrypt runs a public bug bounty for security researchers. PGPony does not (yet).
  • Browser extension too. Chrome extension for desktop Gmail. PGPony is mobile-only by design.

Where PGPony wins

  • No account, no sign-in. Install PGPony, generate a key, done. FlowCrypt for individuals also works without an account for offline use, but the Gmail-integrated flow requires Google sign-in. PGPony never needs any sign-in.
  • Channel-independent. PGPony encrypts text and files for use in any channel — email, SMS, Slack, paste sites, code review tools. FlowCrypt is email-oriented (especially Gmail). For non-email PGP usage, PGPony fits better.
  • OpenPGP v6 import today. PGPony imports v6 keys, decrypts v6 messages, and verifies v6 signatures right now. FlowCrypt\'s consumer-facing v6 support is still in progress.
  • QR code key exchange. Hand someone your public key by scanning a QR — useful for non-email handoffs. FlowCrypt does not have this.
  • Per-decryption biometric prompt. PGPony optionally requires Face ID / fingerprint for every single decryption, not just app open. FlowCrypt uses app-level biometric lock.
  • Six-language localization. English, German, Spanish, French, Japanese, Brazilian Portuguese fully localized. FlowCrypt is primarily English.
  • Free, no tier limits. PGPony has no scale ceiling and no "Pro" upsell. FlowCrypt is free under 100 users but paid above.

Use case fit.

The cleanest mental model: FlowCrypt is "encrypted Gmail with PGP under the hood". PGPony is "a PGP toolbox you reach for from anywhere on your phone".

The verdict.

  • Choose FlowCrypt if Gmail is your primary email and you want PGP woven into that workflow specifically. Or you\'re deploying encrypted email across an organization and need central administration. Or you value the enterprise-software qualities (funded company, bug bounty, support contracts).
  • Choose PGPony if Your email is non-Gmail. Or you encrypt content outside email (files, SMS, paste sites, Slack). Or you want OpenPGP v6 import today. Or you prefer no-account, no-sign-in, local-only key management. Or you\'re part of a multilingual audience (six languages localized).
  • Try both if Free is free. Install both, generate the same key in both, see which workflow feels right. The OpenPGP standard means there\'s zero lock-in — your key works in either app forever.
