Why this exists.

Most language apps treat you like a beginner. After a year, the apps that helped you start now insult you. They teach you "the dog drinks beer" when what you need is the words for the email from your son's daycare. This was built because that gap got too wide to ignore.

The people we built this for can already get through groceries. They can order coffee, mostly. They have a partner or a child or a colleague who is Finnish, and a slowly growing list of moments — parent-teacher meetings, doctor's appointments, dinner with the in-laws — that they keep side-stepping in English. The frustration isn't with the language. It's with their own apps.

Spaced repetition is not the problem. It's the right tool; it's been the right tool for decades. The problem is that nothing between the user and the algorithm has ever known what conversation the user was about to have. So the cards have been generic. Now they don't have to be.

The point is not that the app studies for you. The point is that the twenty minutes you spend studying are spent on the right twenty cards.

Lingo is a small thing, intentionally so. There is no streak system. There is no leaderboard. There is no mascot to be disappointed in you. The review session is quiet and ends when it ends. The product trusts you to come back when the next conversation is coming up.

Lingo is made by Qatalytic Oy, a one-person company based in Helsinki, Finland. The first version ships in 2026. If you want to know when, the changelog is the place to watch.
