About Tide & Co
Tide & Co had a validated web product and a waitlist asking for a mobile app. They needed native-feeling iOS and Android apps fast — without hiring two mobile teams or stretching the launch across two quarters.
They wanted one senior team that owned design, build, and store submission end to end, on the same triple-lock guarantee as the rest of their engagement.

“Signed on a Monday, first build was on TestFlight by Friday. By far the smoothest vendor onboarding I have run.”
The problem
What they came to us with.
01
Ship native-feeling iOS and Android from one codebase, without doubling the team.
02
Keep parity with the existing web product while adding offline-first mobile flows.
03
Get through App Store and Play Store review the first time, on a fixed launch date.
Our approach
How we thought about it.
We shipped the smallest version that proved the core loop, then built the rest from real usage — not the whole brief at once.
01 / One codebase
One codebase, two platforms
React Native + Expo so a single senior team shipped both stores with native performance and platform-correct UX.
02 / Offline-first
Offline-first from day one
Local-first data with sync so the app kept working on the subway — not an afterthought bolted on at the end.
03 / Store-ready
Built for first-time approval
We handled entitlements, privacy manifests, and store assets, so both submissions passed review on the first attempt.
The deliverables
What was built.
01 / Module
React Native + Expo app for iOS and Android from a single TypeScript codebase.
02 / Module
Offline-first sync layer keyed to the existing web API.
03 / Module
Push notifications, deep links, and in-app purchase wiring.
04 / Module
App Store + Play Store submission, assets, and release pipeline.
Under the hood

- React Native
- Expo
- TypeScript
- Node.js

What we learned
The honest takeaways.
Every project teaches us something. Here's what this one taught us.
Prove the loop before the polish
Shipping the core flow in week two meant every later decision was based on real usage, not the founding brief’s assumptions.
Store review is a design input
Treating App Store and Play requirements as constraints from day one is what got both submissions through on the first pass.
One team beats two
A single senior team on one codebase shipped faster than two platform teams would have — and there was no parity drift.
