The short version

  • Only Canary Mail has a free tier, so it costs nothing to try first.
  • Each has a real cost: Canary Mail pGP encryption only protects a message if the recipient also supports and uses PGP, so most everyday mail to non-technical contacts stays unencrypted regardless.; Streaks it is iOS and Apple Watch only, with no Android version, so it is not usable for anyone outside Apple's ecosystem.
  • They diverge on capability: Canary Mail covers AI Copilot, Streaks covers Streak tracking.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Canary Mail

  • PGP encryption only protects a message if the recipient also supports and uses PGP, so most everyday mail to non-technical contacts stays unencrypted regardless.
  • Team and shared-inbox features are minimal compared with Spark or dedicated tools, so it does not suit a support team out of the box.
  • The lifetime purchase price and terms have shifted over past versions, and buyers should confirm current lifetime pricing directly before assuming it still applies.
  • AI features still require sending thread content to a processing service to generate drafts and summaries, so the privacy story is stronger for encryption than for the AI layer itself.
  • Windows and Android apps have historically received updates later than the macOS and iOS versions.

Streaks

  • It is iOS and Apple Watch only, with no Android version, so it is not usable for anyone outside Apple's ecosystem.
  • The base app caps at 24 tracked habits, which is enough for most users but a real limit for anyone wanting to track a larger number of items.
  • Sync is via iCloud only, so there is no web or cross-platform account, which limits use to Apple devices exclusively.
  • It has fewer social or accountability features, such as shared habit tracking with friends, compared with some subscription-based competitors.
  • A single lifetime purchase means no ongoing development revenue tied to the individual user, so it depends on new sales and occasional priced major updates rather than recurring income to fund development.
