Ownership
Own what you pay for
We want people to be able to pay once for an app and keep using it. The goal is low-cost software with a real core experience, not a stripped-down product that keeps asking for more money after the purchase.
Independent Apple platform software studio
Useful Apple apps you can buy once and keep.
Jintus Labs exists to make the kind of software we wish more developers still made: useful apps you can buy, keep, and use without being pushed toward ads, subscriptions, or constant upsells. If you spend money on an app, you should be able to own it and rely on it offline for normal use.

About Jintus Labs
Software you can buy, keep, and actually use
Jintus Labs is built around a simple belief: software should respect the person who bought it.
Approach
Not built around squeezing every user
A lot of software moves toward ads, subscriptions, and artificial limits because the business is built to maximize revenue at every step. Jintus Labs is structured differently, so the focus can stay on straightforward pricing, privacy, and tools people can actually keep.
Language apps
Built to augment, not replace, every other tool
Spanish Cards and Hangeul are being built to take learners from zero knowledge toward A2-level fluency, while still working alongside other classes, books, and apps. The world does not just need more AI-driven, gamified, immersion-first products. Those tools have their place, but some learners want something calmer, more direct, and easier to return to on their own terms.
