Breadcrumbs.
Your automatic night-out diary.
While you're out, Breadcrumbs quietly tracks every venue, photo, payment, ride, and song. Wake up the next morning to a complete timeline of your night — stored exclusively on your phone.
iOS 17+ · Free + Premium · 100% on-device
How it works
- 01
Carry your phone
No check-ins, no buttons, no logging. Breadcrumbs runs on iOS's optimized motion stack — the same low-power monitoring that Find My uses.
- 02
Live your night
Venues, photos, spending, rideshares, music, weather, and health metrics get correlated silently. Sensitive locations are auto-hidden.
- 03
Wake up to a recap
Morning notification opens a complete timeline of your night, with a color-coded map and directional transit arrows from venue to venue.
- 04
Edit, share, or forget
Adjust visits with a tap, share an encrypted night with a friend (Premium), or wipe everything in one swipe. Nothing leaves your phone without your consent.

Privacy as the product
Most night-out apps treat your data as a business asset. Breadcrumbs treats it as a private journal that happens to live on a glass rectangle in your pocket.
- On-device only
All data stored exclusively on your phone. No cloud account. No analytics. No ads. No tracking.
- Sensitive locations hidden
Healthcare, legal, religious, and mental-health categories are auto-hidden by default. You can add custom hidden zones for any address.
- Encrypted sharing
Sharing a night with a friend uses an AES-256-GCM encrypted link. The server only ever sees ciphertext — the key never touches it.
- Locked behind biometrics
Face ID / Touch ID app lock with Secure Enclave token protection. App switcher and notification privacy screens included.
- One-tap wipe
Settings → Wipe Everything erases all on-device data instantly. Uninstall does the same — nothing exists on a server to recover.
Beta access
Field-testing in Delray Beach.
Beta testers wanted.
Open beta is live on TestFlight for iOS 17+. Fifty seats, first-come first-served. We're looking for testers who actually go out — bars, restaurants, live shows — and will tell us what broke. Feedback in-app or to corey@slick-engineering.com.
FAQ
- Does this drain my battery?
- No measurable impact for most testers. Breadcrumbs uses iOS's CLVisit and significant-location-change APIs, the same low-power motion-coprocessor monitoring that Find My uses. There's no continuous GPS polling.
- Do I have to do anything during the night?
- No. Carry your phone like you normally do. Open the app the next morning to see your reconstructed timeline.
- Where is my data stored?
- Exclusively on your phone. There is no cloud account, no server-side database, and no analytics endpoint. Bank and email integrations route through Cloudflare Workers that only forward signed requests — they never see or store your transaction data.
- Can I share a night with friends?
- Yes, with Premium. Shared nights travel as an AES-256-GCM encrypted blob; the server holds only ciphertext, and the decryption key lives in the share link itself. If the link is never shared, the data is unreadable.
- What happens when I uninstall?
- Everything is wiped. There is no server-side copy to recover. We do not store an account, an email address, or a backup unless you explicitly export one to a file on your own device.
- What does Premium unlock?
- Bank-transaction matching (Plaid), email rideshare/dining receipts, Apple Music history per venue, calendar matching, flight detection, encrypted night sharing, encrypted backup/restore, face-companion clustering, the Your Places heatmap, venue search, self-learning venue names and transit modes, and unlimited retention. $3.99/month or $29.99/year.
- When is this on the App Store?
- TestFlight-only for now. The App Store launch comes after the beta cohort has worked through real nights out and submitted feedback.
- Why is it called Breadcrumbs?
- You leave a trail of digital signals through your night — venues, photos, payments, music. Breadcrumbs picks them up automatically and stitches them into a single story.
