What Size Am I?
Never guess their size again. A private family app that keeps everyone's clothing, shoe, and brand-specific sizes in one place, so shopping trips and gift-buying stop starting with a text asking what size the kids wear now.
Get In Touch
Every family has this problem
Kids outgrow shoes every few months. One brand's medium is another brand's small. Grandma wants to buy a gift and needs a size right now, not a guess. What Size Am I? is a small, private app for keeping that information somewhere it's actually findable, instead of scattered across old receipts, text threads, and memory.
What it does
Family Profiles
One place for everyone's sizes: clothing, shoes, and more, organized per person instead of buried in separate notes.
Track by Brand
Sizes vary by brand, so each brand gets its own tracked size instead of one generic number that's wrong half the time.
Body Measurements
Height, chest, waist, inseam, foot length, and more, for matching against a brand's actual size chart instead of guessing.
Needs Checking
Sizes that haven't been confirmed in six months get flagged as worth a look, not assumed wrong, just due for a check. Handy when kids grow fast.
Fit Reports
Flag "this doesn't fit anymore" the moment someone notices, too small, too big, uncomfortable, or worn out, and it surfaces the next time anyone checks.
Seasonal Reminders
An occasional nudge before back-to-school or winter hits, not constant nagging.
Shopping Card & Gift Sizes
Generate a shareable summary of someone's sizes for yourself while shopping, or to send to a relative buying a gift. Anything marked private stays out of it automatically.
Check Tab
One screen that surfaces everything worth a look: stale sizes, reported fit issues, and seasonal prompts, so nothing gets missed between shopping trips.
Private by design
What Size Am I? doesn't run on a server, doesn't require an account, and doesn't send your family's information anywhere unless you choose to share it.
Everything stays on the device. Household, family member, size, measurement, and fit-report data are stored locally using Apple's on-device SwiftData storage. There is no What Size Am I? cloud or backend, and no account to create.
Photos never give the app broad access. Profile photos are chosen through Apple's built-in photo picker, which hands the app only the single photo you select. It never sees the rest of your photo library.
Sharing is always your call. Shopping Card and Gift Sizes only generate a summary when you ask for one, and it excludes anything you've marked private. What you do with that summary, like who you send it to, is up to you.
Reminders stay on your phone. Seasonal reminders are scheduled locally and require your permission to enable. Nothing about your family's sizes leaves the device to make that happen.
