A small London studio building consumer software the deliberate way. Long arcs, short releases, products that hold up.
Stack & Stone is a small London studio behind a focused portfolio of consumer apps. We work in long arcs and short releases, with a preference for products that hold up to repeated use.
Most software is built to scale. We build to fit: products with a clear shape, a defined audience, and a reason to exist beyond the first download.
"Built deliberately, then maintained patiently."
A living book of your baby’s first years.
Feeds, sleep, growth and firsts, written down as they happen and gathered into a keepsake you can print. It lives on your phone and in your own iCloud. No account, no ads, no analytics.

A daily puzzle for planners.
One sheet a morning, the same one for everyone, about five minutes. Nineteen puzzles drawn from the work planners and project controls people actually do, and every answer shows its working, win or lose.

Most apps say too much, ask too often, and notify too loudly. Ours hold their tongue. The room is quiet so the work can be heard.
We treat performance, accessibility, and data discipline as load-bearing, not as polish to be added when there's time. There is never time.
The studio takes on a small number of partnerships each year. If you're working on something that could fit, write. Short and specific is better than long.
Press, podcast, and speaking enquiries also welcome.
