## What is Proof?

If it happened, prove it.

Proof creates tamper-evident, timestamped records of anything you need to document. Take a photo or video, add notes, and Proof seals it with a cryptographic hash — a unique digital fingerprint that makes it virtually impossible to alter the record after the fact.

Whether you're photographing an apartment before moving in, documenting a car accident, recording an agreement, or tracking the condition of something you're lending — Proof gives you a credible, shareable record with a verifiable timestamp.

What makes Proof different
Every proof is sealed with a SHA-256 cryptographic hash computed from your photos, videos, timestamp, GPS location, and notes. If any detail changes after sealing, the hash won't match — making tampering obvious. A hash chain links each proof to the one before it, creating a lightweight audit trail across your entire vault.

Built for real situations

• Move-in and move-out apartment photos
• Car accident and property damage documentation
• Item condition records before and after lending
• Agreements and acknowledgment tracking
• Workplace incident reports
• Online marketplace sales and shipping evidence
• Generate a professional PDF export containing your photos, full metadata, GPS location, cryptographic hash, and a QR code for easy verification.
• Share via AirDrop, text, or email. 
• Request acknowledgment — recipients can confirm receipt via a secure link, and you'll receive a push notification when they do.

Your data stays on your device
No account required. No cloud sync. No tracking. Everything lives on your device unless you explicitly choose to share it.

### 5/5 — Move In Audit

*2026-04-24*

Solid app! Used it prior to moving into our rental in the Philippines. Able to document and send all in a matter of seconds was a seamless process. Thank you!

### 5/5 — Cool idea!

*2026-04-01*

The ability to send a proof for someone else to acknowledge and store a record of it is something I've not seen before. Looking forward to using this more.

## Frequently asked questions about Proof

### What is Proof's primary function?

Proof creates tamper-evident, timestamped records of events. It uses cryptographic hashing to ensure the integrity of photos, videos, and notes, making them virtually impossible to alter after sealing.

### How does Proof ensure evidence integrity?

Each record is sealed with a SHA-256 cryptographic hash derived from the content, timestamp, GPS location, and notes. Any alteration to the data will result in a mismatch of the hash, indicating tampering.

### Can I share my documented evidence with others?

Yes, you can share your records via AirDrop, text, or email. The app also allows you to request acknowledgment from recipients via a secure link, notifying you upon their confirmation.

### Does Proof store my data in the cloud?

No, your data stays on your device. Proof does not require an account, cloud sync, or tracking. All information remains local unless you explicitly choose to share it.

### What kind of export options does Proof offer?

Proof can generate a professional PDF export that includes your photos, full metadata, GPS location, the cryptographic hash, and a QR code for easy verification.

### Is Proof suitable for legal documentation?

Proof is designed to create credible, shareable records with verifiable timestamps, which can be useful for documenting incidents, agreements, or conditions for potential legal use.

### How often is Proof updated?

The latest version, 1.3.4, was released on April 3, 2026, indicating recent development activity. Updates typically aim to improve features and reliability.

### What devices does Proof support?

Proof is available for iPhone and iPad devices, making it accessible to a wide range of Apple users.
