A movie and TV companion app for tracking what you watch, keeping a watchlist and deciding what to watch next.
For people who love movies and TV and don't need a word for it.
The problemWatchlists live in phone notes, reviews in texts to friends and release dates in memory, while the existing apps feel clunky, dark and built for performative reviews.
In development
- In development
A wishlist and price-tracking app for thoughtful shopping.
For online shoppers who save things to buy later and want to know when prices change.
The problemSaved items end up spread across tabs, screenshots and store wishlists, and price drops are easy to miss.
- In development
A countdown app for the moments that matter.
For anyone counting down to a trip, an event or a date they care about.
The problemA calendar shows when something happens, not how close it is, so the moments people look forward to get lost among everyday entries.
- In development
A cycle-aware health companion that explains what your hormones are doing, in plain language.
For people who track their cycle and want to understand it, especially when migraines, mood or medication follow it.
The problemPeriod trackers say when. They rarely explain what is happening in between, or when a migraine window or a medication matters.
Strategy is invisible
until it compounds.
How the studio works, shaped by building real things
- Step 1 of 3
Define
Start from a real problem
Each product starts with a specific problem and a clear idea of who it is for.
Not features in search of a use.
- Step 2 of 3
Prioritise
Decide what matters
Scope the smallest version worth launching, and make the trade-offs explicit.
Not a roadmap that tries to do everything at once.
- Step 3 of 3
Launch
Ship it end to end
Design, build and release the product, then keep improving what is live.
Not a prototype that never leaves the folder.
