Free apps, given away.

Alongside our client work we build tools we felt were missing — and give them to everyone. No charge, no ads, no data collection and no hidden business model. Out of plain, genuine goodwill: if it helps you, take it. If it helps someone you know, send it to them.

Completely freeNo adsNo data collectionNo in-app purchases

Why? Every one of these apps grew out of a real need — someone in the family, in the community, or our own. Once the tool worked, we saw no reason to put it behind a paywall. There is no premium tier, no free trial that runs out, and no plan to start charging tomorrow. The only thing we ask: if you liked it, tell someone.

Free, no asterisks

No payment, no subscription, no in-app purchases and no ads. Not in the future either.

Your data stays with you

Most of these apps have no server at all — settings and history live on your device and vanish when you uninstall.

Grounded in research or sources

Where a feature rests on a scientific study or a halachic source, it is written on the app's page, with a link. We do not promise what the research does not show.

The same engineering as the paid work

These are not demos. The same care for simplicity, accessibility and stability we bring to systems built for clients.

The Apps

Five tools, seven apps

Each app has its own page: what it does, what makes it special, screenshots — and the research behind it. The apps themselves are in Hebrew.

Android · Screen time

Time Guard — you decide when the phone is open

Rules written as single sentences, declaring up front how long you will scroll, blocking Shorts and Reels, and a "cool-down" that protects your decision from the impulse of the moment. Built on the research on screen overuse.

Google Play · No server · No internet permission

Browser · Concentration

Focus Sounds — quiet that works

Brown, pink and white noise and rain, generated live in the browser, with a work timer. Based on the research on background noise and attention — including what the research does not prove.
