About Life Software Lab
Life Software Lab is an independent Android developer based in South Korea. We build small, focused apps that do one job well and respect the person holding the phone: no accounts, no data harvesting, no permission creep.
What every app promises
Free
Every app is free to install and use. Ads keep the lights on; core features are never behind a paywall.
No account or sign-up
Nothing to register, nothing to remember. Install, open, done.
On-device by design
Your data stays on your phone. We run no user database, so there is nothing of yours to leak.
No unnecessary permissions
Each app asks only for what its job needs, and asks at the moment it needs it.

Support and contact
Questions, bug reports and feature ideas are welcome. Email us and we reply in English or Korean, usually within a few days. Every app's privacy policy and terms are linked from its own page.
