KLO

About this project

KLO is a custom product designed, developed, tested and deployed by our team, with the source code and accounts handed over to the client.

A utility mobile application: the category where users judge the product in the first five seconds. Utilities are opened often, used briefly, and uninstalled the moment they feel slow, so cold-start time and battery behaviour matter more than feature count.

What a build like this covers

• Fast cold start with work deferred off the launch path
• Local-first data so the main screen renders without waiting on the network
• Background sync scheduled through the platform’s own scheduler rather than a wake lock
• Widget and quick-action entry points where the platform supports them
• Settings, permissions and a clear explanation of why each permission is requested

What we watch for in utility work

Utilities are tested on low-end Android hardware, not on a flagship. A screen that is instant on a recent device can take three seconds on the phone most of the user base actually owns.

Stack

We build utility products in Flutter and native Android and iOS on the client, with Node.js and NestJS services behind them, TypeORM over PostgreSQL or MySQL where the data is relational, MongoDB where it is not, and Firebase for authentication, push and analytics. Web panels are React. The choice follows the product. We do not start from a template and bend the requirements to fit it.

How we work

Every project starts with a written scope and screen list, moves through design and iterative development with regular demos, and ends with testing on real low-end devices before release. Clients own their code, repositories and store accounts. Where it adds genuine value, we integrate AI features (assistants, document extraction, recommendations) rather than bolting them on for show.
