Why the nudge lands at 5:30pm

Most reminder apps fail the same way: they tell you something true at a moment you can do nothing about it. A “your spinach expires today” alert at 11am reaches someone at work, forty minutes from their fridge, who will have forgotten it by the time it matters. The information was right. The timing made it useless.

Pantry’s notification design starts from the opposite end — not “when did this become true” but “when can a person act on it.” In a kitchen week, there are two such moments.

7:30am — the planning moment

The morning digest lands at 7:30am, before the day has made its plans: what is turning this week, and what it is worth. Morning is when the shape of the day is still negotiable — who is home tonight, whether something should move down from the freezer, whether the shop on the way home is needed at all. The digest is deliberately a summary rather than an alarm, because the morning decision is a planning decision. It is also built to reach every phone in the household, not just the one that scanned the receipt — a plan only one person knows about is not a plan.

Every plan gets the digest. It is the baseline loop: see the week, steer the week, the quiet version of the Sunday hour run daily in ten seconds.

5:30pm — the decision moment

The second notification is the Pro nudge, and it is timed to the most consequential moment in household food waste: early evening, when “what is for dinner” gets answered. This site keeps returning to the argument at 5:30pm for a reason — it is where the leftovers lose to takeaway and where the mince’s last day slips by unnoticed. The nudge arrives inside that window, while acting on it is still possible: home soon, shops still open, dinner not yet decided.

And it is built to name a meal, not a deadline. The standing example: “Your lean beef mince goes off tomorrow. Spaghetti bolognese tonight and it never sees the bin.” The difference between that and “1 item expiring” is the difference between a decision made and a fact filed away — an alert that hands over a plan costs nothing further to act on.

Two, and no more

The quietest design decision is the ceiling. Two timed notifications a day is the lot, because an app that pings every time something ages becomes an app that gets muted, and a muted expiry tracker is a $48-a-week leak with an icon. Notification design for a years-long habit optimises for the day you keep listening, not the day you install — so each one has to arrive when a decision is live, say which food and which meal, and otherwise stay silent.

That is the entire philosophy: the data behind the countdown decides what is true, and the clock decides when saying it can still change dinner.
