Never buy the wrong size again. Save your clothing and shoe sizes, share them with family and friends, and make Secret Santa easy this year.
Pants 32, but 34 at that one brand. Shoes 9, boots 9.5. Your sister's ring size, your dad's favorite colors. Sizebook keeps everyone's clothing and shoe sizes in one place, so you buy the right fit the first time.
SAVE YOUR SIZES
• One usual size per category: T-shirts, shirts, knitwear, coats, pants, jeans, shorts, dresses, skirts, suits, underwear, bra, swimwear, socks, shoes, sneakers, boots, hats, gloves, rings and belts
• Fit (slim, regular, relaxed) and notes for every size
• Body measurements in cm/kg or in/lb
• Approximate size conversion EU/UK/US/US women/JP for shoes, dresses and skirts, suits and bras
BY BRAND
• Add exceptions per brand: "pants 32, but 34 at this brand"
• Where are you shopping? Type a brand and see the right size for anyone
SHARE WITH YOUR GROUPS
• Groups for family, home, friends, couple, Secret Santa and work
• For each group, choose what it sees: sections, measurements, gift notes
• Groups on this iPhone for people without the app, like kids or grandparents
GIFTS WITHOUT GUESSING
• Gift notes: likes, dislikes, colors, favorite brands
• Wishlist with links and prices
• Claims: members tap "I'll get it" so nobody buys the same gift. The owner never sees claims, so the surprise stays
• Secret Santa: draw names, set a budget and a date. Each person sees only the sizes of the person they drew
FOR GROWING KIDS
• Size history for every category
• "Time to check" reminders every 6 months, before last season's shoes stop fitting
PRIVATE BY DEFAULT
• No email, no password: start without an account or Sign in with Apple
• "Only me" entries never leave your account
• No ads, no tracking
FREE AND PREMIUM
Free: your own sizes, brand exceptions, measurements, gift notes, wishlist, privacy controls, joining groups, groups on this iPhone, units and app icons.
Premium is optional (monthly, yearly or lifetime) and adds: creating and managing shared groups, the Secret Santa draw, adding people without the app to shared groups, wishlist claims, size history with check reminders, and size conversion. Prices are shown in the app.
The right size, for you and for everyone you shop for.
