InkStamp is a small iOS app that lets you watermark photos the way old photo labs used to: fast, tactile, and with character. Single photos, whole shoots, or invisible marks that survive screenshots — every pixel is processed on your iPhone.
Layer text, logos, and retro decor effects. Font, tint, rotation, and opacity — all controlled from a single panel.
Drop in an entire shoot, pick one preset, and export the lot in one tap. Free up to three images, Pro for unlimited.
Embed an imperceptible watermark that persists across crops and screenshots, verifiable from the InkStamp detector.
Save your go-to stamps so every export stays on brand, without re-adjusting the rotation for the hundredth time.
No sign-in. No analytics. No photos uploaded. Purchases go through Apple — we never see your card or your Apple ID.
Cream paper, coral ink, mint accents. Because professional tools should feel good to use, not just effective.
¥2.99 / month. Auto-renewing subscription. Unlocks every Pro feature including invisible watermarks and unlimited batch exports.
US$9.99 / year. Auto-renewing subscription. Same feature set as monthly, renewed once a year.
US$19.99, one-time. Non-consumable purchase that never expires and restores free of charge on any device signed into the same Apple ID.
All prices are billed through Apple. Manage or cancel any time in iOS Settings → Apple ID → Subscriptions. See Terms of Use for full auto-renewal disclosures.
