Inflation Shield — stock up before prices rise

A free tool that watches the prices of things you actually buy and tells you what to stock up on now, before they get more expensive — built entirely from your own scanned receipts, no AI required.

What it is

Inflation Shield forecasts where the prices of your regular purchases are heading, based on your own buying history. When something you buy often is trending up, it suggests buying a bit extra now — how many, at which store, and roughly how much you’d save by not waiting. It also keeps a running total of how much the Shield has saved you so far.

It’s completely free, uses no AI, and works entirely from receipts you’ve already scanned — there’s nothing extra to set up.

Where to find it

• The Inflation Shield card on the Home screen shows a quick preview — tap it to open the full screen.
• You can also just ask the AI chat things like “What should I stock up on?” or “What’s getting more expensive?” and it will pull the same recommendations into the conversation.

What the screen shows

• Saved so far — an estimate of how much the Shield has already saved you, at the top of the screen.
• Your basket’s forecast — where your typical spending on these products is headed next month.
• Buy-ahead cards, one per product trending upward:
• the product, and how fast it’s rising (e.g. +8%/month)
• a suggestion like “Buy 4 — save ~12 zł”
• the store where you usually buy it
• an “affordable today” badge when buying now fits your Safe-to-Spend budget

How it works

Inflation Shield is built entirely from the line items on receipts you’ve scanned (by photo or bank-notification capture). You’ll need a few receipts with the same product before it has enough history to spot a trend — the more you scan, the better the forecasts get.

It’s also selective: it only suggests stocking up on things that make sense to keep around for a while, like pantry staples and household goods. It won’t tell you to hoard milk or anything else that spoils quickly.

Every number you see — the trend, the suggested quantity, the savings — is a forecast and an estimate, not a guarantee. Real prices can move differently than predicted.

Sharing

Tap Share to create a “My Inflation Shield” image (or a text summary if image sharing isn’t available) highlighting what you’re saving. A Hide amounts toggle masks your money figures first, in case you’d rather not show exact numbers.

Good to know

• Inflation Shield is free for everyone — no Pro subscription needed.
• Prices and savings are shown in your display currency.
• Recommendations are based only on your own purchase history for now. Comparing prices across other users’ purchases nearby, to suggest the cheapest store, is planned for a future update.
