ZeroWhen

Zero effort. Tell me when.

ZeroWhen waits for things, so you don't have to. Tell it what you're waiting for, in your own words. It checks for you, day and night, and tells you the moment it happens.

Things you can ask

• Tell me when Blundstone 585 boots are back in stock in men's size 9
• Tell me when flights from Vancouver to Lisbon drop under $700
• Tell me when Tioga Road in Yosemite closes for the winter
• Tell me when Whistler Blackcomb announces its opening day
• Tell me when coffee is on sale in the Real Canadian Superstore flyer
• Tell me when the Bank of Canada changes its interest rate

How it works

1. Say what you're waiting for. In the app, or ask your AI assistant to set it up.
2. ZeroWhen checks for you. As often as you like, for as long as it takes: days, weeks or months.
3. You hear from us when it happens. On your phone or by email, and nothing in between. Every Sunday, one short email tells you that each watcher is still checking.

We play by each website's rules. Some say no to software, and we respect that. Often their own alert emails get you there anyway. Playing fair is how we keep ZeroWhen cheap, and our conscience clear.

Our promise

We charge you; we don't study you.

• No ads. We never sell your data. We never use anyone's data to train AI.
• We use as little of your data as we can. A watcher sees only the page you gave it, the part to look at, what you're waiting for, and the pages it reads. When AI checks a change for you, it sees only that change. It can't click, buy or send anything.
• If you delete your account, we delete its data within 24 hours. It's gone from our backups within 30 days.
