## What is SignedApproval?

SignedApproval puts you in control of your AI agents.  When an AI agent needs to take a high-stakes action — sending an email, making a purchase, modifying code, or accessing sensitive data — SignedApproval sends an approval request directly to your iPhone.  You approve or reject it with a single tap. Every decision is signed with Ed25519 cryptography, creating a tamper-proof audit trail.


## Version history (last 5 releases)

### 1.0.3 — 2026-08-30

• Approve from your wrist or lock screen — tap Approve or Reject right on the notification, secured by your device's Secure Enclave
• Richer request details — see what an agent is about to do, risk findings by severity, and a verifiable argument fingerprint before you decide
• High-impact requests (like production deploys) are now held out of "Approve All" and always require individual review
• Requests with no deadline now display correctly
• Faster, more reliable approvals — clearer error messages and improved service resilience
• Bug fixes and stability improvements

### 1.0.2 — 2026-07-04

This update strengthens how your approvals are verified and adds a new way to prove you're human in email. Face ID and passkey approvals now verify your identity through a cryptographically signed assertion end-to-end, closing a gap where a weaker verification method could be used instead of the one you set up, and fixing a bug that could trigger Face ID twice in a row. We've also brought Email Stamps to the app: verify your email identity right on your device and generate a signed, verifiable stamp — with a link, HTML badge, or plain-text fallback — that proves a real person authored your message. Under the hood, we updated several dependencies to patch known security advisories, with no change to how the app works.

### 1.0.1.4 — 2026-06-01

Bug fixes.

### 1.0.1.3 — 2026-05-17
