Independent software studio
Sesin IT builds native apps for iPhone and iPad. Every one of them runs on the device, keeps your data where you put it, and asks for nothing it does not need.
Three decisions we made once and have not gone back on. They shape every app we build.
Your data is stored on your iPhone and synced through your own private iCloud. We do not run a database with your information in it, because the safest place for it is somewhere we cannot reach.
Install and start. There is no sign-up form, no advertising, no analytics SDK and no third party watching what you tap. Nothing about you is for sale, because none of it reaches us.
Written in Swift for Apple's own frameworks — not a website in a wrapper. That is what makes them fast, work offline, respect the system settings you already chose, and survive the next OS release.
Every app has its own page here, its own site, its support page and its privacy policy.

Routines, form and food
A complete trainer for iPhone and iPad: 21 programmes from one to twelve weeks that tell you what to do each day, and 127 exercises with their own animation you can slow to half speed to study the technique. Guidance by age from 6 to 90, including a postpartum track, plus meal plans whose calories come from your weight and activity, not a generic table.

Track your money by voice
Say what you spent and Saldy writes it down, categorised — the speech recognition runs on your iPhone, so no audio ever leaves the device. Reports that show where the money actually goes, budgets that roll over, and a forecast that names the exact date you would go into the red, before it happens. 166 currencies.

Languages and maths at home
Teaches Spanish, English and French — in all six combinations — plus maths, for the whole family in one app. Spaced repetition, whole sentences instead of loose words, conjugation rather than infinitives, and pronunciation it listens to on the device. Six age modes, from a baby screen you cannot fail to an adult keyboard. No account, no servers, works fully offline.

Work with us
Most of what we do is our own apps. The rest of the time we take on work for other people — the same way, with the same standards.
We read everything that arrives, and a person answers.
