Tension index
A transparent open-source estimate of the chance of an event in the next 7 and 30 days, with a public accuracy record and calm alerts. Works as a website and as an app you add to the home screen from the browser.
Open · Alerts · Family circle
-
Quiet moment
Breathing and grounding during and after a siren, a kids' version, how to talk with children, and help lines. Based on Israeli professional sources, works offline.
-
Safe Travels
A safety score for Israelis in every country: the official travel warning and how Israelis are treated on the ground. Also cheap flights from Tel Aviv and a vacation planner.
-
Emergency Rights
A plain, calm guide: how to claim compensation from Property Tax for war damage, and what reservists and their partners are entitled to. Every item links to the official source.
-
Ready Home
An emergency checklist that fits who lives in your home, where to check what is allowed in your area today, and a map of public shelters. No tracking.
-
Israel Quakes
What was felt in Israel, where and how strongly: a felt-intensity map, public "I felt it" reports and a history of quakes. Not an alert service; in an alert, follow the Home Front Command.

Who built this
Chen Cohen
Entrepreneur, builder of websites and apps
I like taking an idea and turning it into something people actually use. I always have a few ideas on the table, and the thinking interests me as much as the building: understanding what people really miss, and finding the simplest way to give it to them. The tension index started with one question, how tense is it really right now, and became an engine that reads dozens of sources, computes probabilities and publishes its own accuracy record.
I build websites and apps of every kind: a landing page or a business site, a phone app, all the way to complex systems with real-time data, alerts and AI.
