The fast, fan-approved way to scan, identify, and estimate values for postage stamps — with smart pre-grading, eBay market analytics, and a clean collection manager built for real philatelists.

SCAN & IDENTIFY IN SECONDS

Point your camera at a stamp and Cent recognizes country, year, denomination, Scott/Michel catalog info, and issue type. Add to your digital album with one tap.

WHY TRY IT

Instant ID – Visual match + OCR for classic & modern issues across USA, UK, Germany, China, Commonwealth, and worldwide.

Value Snapshot – See a ballpark price by condition tier (Mint NH / Hinged / Used / Cover), with quick comps.

eBay Analytics – Live listings count, median asking price, min/max, and a carousel of current listings you can tap through.

Condition Coach – Take 3 guided photos (Front, Perforations & Centering macro, Back/Gum). Get hotspots for missing teeth, heavy cancellations, creases, gum condition, and centering, plus a suggested pre-grade (e.g., “XF-Sup 95 ±10”).

Private & On-Device – Your collection lives on your iPhone. AI lookups send minimal text only.
