The screenshot graveyard problem
The average iPhone has 200+ screenshots sitting in the camera roll. A huge slice of those are vouchers, coupons, gift cards, and promo codes you screenshotted with every intention of using — and then forgot existed.
By the time you remember the $20 off Sephora voucher, it expired three weeks ago. The Starbucks rewards email? Gone. The Ulta birthday gift? Wasted. Multiply this across a year and most people lose hundreds of dollars in deals they technically owned.
How Snaap solves it
Snaap is a voucher reminder app built specifically for the way people actually use screenshots. You don't change your behavior — just keep screenshotting deals like you always do.
Step 1 — You take a screenshot
Spot a deal in an email, a brand's Instagram post, or a banking app promo? Screenshot it like usual. No copying. No manual entry. No new app to learn.
Step 2 — Snaap reads it on-device
In the background, Snaap uses Apple's Vision framework plus a Core ML model trained on thousands of voucher layouts to extract the expiry date, the brand, and the discount value. Everything happens on your iPhone. No cloud upload. No account.
Step 3 — You get reminded before it expires
Snaap sends you push notifications:
- 3 days before — early heads-up so you can plan to use it
- 1 day before — last chance reminder
- The morning of expiry — use it or lose it
One tap to mark a voucher as used. No manual data entry. Ever.
What kinds of vouchers does Snaap handle?
Snaap recognizes the full long tail of voucher formats screenshotted by iPhone users:
- Promo codes from email newsletters (Sephora, Ulta, Nike, ASOS, etc.)
- Loyalty rewards from Starbucks, Chick-fil-A, Dunkin', and other brand apps
- Gift cards with expiry dates from retailers and gift card vendors
- BOGO deals and restaurant coupons from screenshots of social media posts
- Bank promo offers (Chase Offers, Capital One, Amex deals)
- Subscription discount codes from welcome emails
- One-time use codes from referral programs
If the expiry date is readable in the image, Snaap can usually extract it. If extraction fails on an unusual layout, you get a gentle prompt to set the date manually — no broken silent failures.
Why on-device matters for a voucher app
Most "AI-powered" voucher apps require you to upload your screenshots to their servers. Think about what's actually in your screenshots beyond vouchers:
- Banking app screenshots with account numbers
- ID photos and passport scans
- OTP / 2FA codes
- Private messages
- Medical info
Snaap was built on the opposite principle: your screenshots never leave your iPhone. Apple's on-device AI frameworks make this not just possible but fast. There's no account to create, no email to verify, no data to sell.
Beyond vouchers
While voucher reminders are Snaap's strongest use case, the same on-device engine handles other expiry-sensitive screenshots:
- Boarding passes and flight confirmations — surfaced the morning of travel
- Concert tickets and QR codes — ready when you need them
- Gift cards with hidden expiry policies
- Hotel check-in confirmations and reservation receipts
- Restaurant booking confirmations from OpenTable and Resy
Frequently asked questions
How does Snaap detect voucher expiry dates?
Snaap uses Apple's Vision framework for optical character recognition (OCR) combined with a Core ML model trained on thousands of voucher layouts. The model extracts the expiry date, brand name, and discount value directly from the image — entirely on your iPhone.
Is Snaap really free?
Yes. The core voucher reminder feature is free with no account required. There's an optional Pro tier ($2.99/month or $19.99/year) that unlocks unlimited screenshot indexing, trip and event grouping, and custom categories. The voucher reminder itself is free forever.
Does Snaap upload my screenshots to a server?
No. Everything runs on-device using Apple's on-device AI frameworks. Your screenshots — and any banking info, IDs, or private messages they may contain — never leave your iPhone. There's no cloud component to Snaap's core feature.
Does Snaap work with Apple Wallet vouchers?
Apple Wallet only handles vouchers issued as pkpass files by participating merchants — a small fraction of real-world vouchers. Snaap covers the long tail: promo codes screenshotted from emails, deals from brand apps, social media offers, and any voucher image with a readable expiry date.
What if Snaap reads the wrong date?
When extraction confidence is low, Snaap shows you the date it detected and asks you to confirm or correct it. You can also override any date at any time with one tap. Snaap learns from corrections to improve accuracy over time.
What iOS versions does Snaap support?
Snaap requires iOS 17 or later for full on-device AI capabilities. It works on iPhone, iPad, and Apple Silicon Macs.
