BodyGravity SN
Personal fitness coaching
A native iOS + Android app for personal training. Built on SN Account for identity, progress sync, and an assistant layer that adapts to the user's weekly plan.

Identity for the next generation of personal apps.
We build SN Account — a single identity and edge runtime that powers our family of personal coaching, learning, and utility apps. One login. One data model. Deployed at the edge, for everyone.
SN Account, the platform underneath.
Five apps, one identity layer. SN Account handles authentication, user data sync, and edge-side logic for the whole SN family — so each product can focus on its craft, not the plumbing.
Unified identity
One account across every SN app. No more "create yet another login" for our users.
Edge-native
Logic runs close to the user. Snappy response in Asia, UK, and North America.
Shared context
Body, learning, and travel data stay private by default — but available across apps with one consent.
Apps on SN Account.
Each app is a focused product. SN Account sits underneath and gives them a single sign-on, shared billing, and a unified data model — without forcing the same UX on every product.
KnowledgeCards SN
Children's knowledge cards
A children's learning app using short, illustrated knowledge cards. Generation pipeline runs on Cloudflare Workers AI and stores media in R2 — both billed through SN Account.
Beta
TubeList SN
YouTube list, organised
A focused YouTube list manager. Group videos into named lists, share them with one link, and pull transcripts on demand for quick review.
Live
張單據夾
Receipt & bill organizer (iOS)
A native iOS app for organising paper receipts and bills from email, photo, or PDF. Built first as a standalone product — now being migrated onto SN Account for unified identity and cross-device sync.
In development
TripBoard SN
Travel planning, done quietly
A privacy-first travel planner. Builds an itinerary from a few constraints, syncs across devices, and exports to the user's calendar without a tracking SDK in sight.
