Business application
Watch the product, not the link
PriceSpark is a Windows app with a Google Chrome extension that recognises a product, finds it in many shops, works out the real cost of buying it with delivery and checks whether today’s price really is a deal – then keeps an eye on it for you. Your products, price history and settings stay on your computer.

PL · DE · CZ
Offers for the same product from shops, comparison sites and marketplaces in one place.
Delivery included
Price, delivery to your country and currency conversion – you see what you will actually pay.
4 ratings
Today’s price compared with the minimum, average and median from the history, not with a “sale” label.
365 days
A year of history on a chart and a notification when the cost drops to your threshold.
40+ services
Flights, stays and holidays from many sites at once, plus a subscription comparison.
On your PC
Products, price history and settings are stored locally – no account in the app and no cloud.
Offer comparison
PriceSpark watches the product, not a single web address. Offers from different shops and markets come together in one place, and identical offers are kept apart from similar variants, bundles and accessories.
Real cost
What counts is the cost, not the headline price: the price, delivery to your country and the currency converted at the current rate. You see the best real cost straight away next to every product.
Deal rating
The deal engine compares today’s price with the product’s history – minimum, average and median – instead of trusting “sale” and “−50%” labels. Every product gets a clear rating.
Price history
A year of price history on one chart: the lowest price, the 90-day average and your threshold. Statistics for 7, 30, 90, 180 and 365 days help you decide whether to buy now.
Alerts
Set a price threshold with one click. The notification arrives in Windows and in Chrome when the cost drops to the threshold – once, without flooding you with messages.
Travel
Search several sites at once, see the results in one table with the cheapest offer highlighted straight away. Every travel search runs in a new, empty Chrome profile.
Choose a plan: a one-off licence or a subscription with updates.
Recommended
Billed monthly
10 € net/month
10 € gross/month (incl. 23% Polish VAT)
Prepaid monthly access. Before the period ends you receive a payment link – no automatic charges.
One-off payment
40 € net
50 € gross (incl. 23% Polish VAT)
A single payment for the licence, with no recurring charges.
Renewal via a payment link before the period ends – no automatic charges; you can cancel at any time.
For now we take orders through the contact form: click “Ask about buying” and I will reply by e-mail with payment instructions.
Gross prices include Polish VAT. For businesses and customers from other countries VAT is calculated in the order summary (e.g. reverse charge in the EU, 0% outside the EU).
Prices in EUR, USD and GBP are indicative – converted from PLN at the NBP (National Bank of Poland) rate and rounded up. Billing and invoices are always in PLN.
A one-off licence is granted for an indefinite period: the application works for as long as we run the service and the licence server. You are buying a licence to use the application, not ownership of it. Details: Terms of sale, § 9.

No. PriceSpark finds offers, works out the cost and notifies you about price changes. You make the purchase yourself, in the shop of your choice.
The app first compares unambiguous codes (EAN/GTIN, manufacturer code), then brand, model and variant, and only then names and specifications. Other variants, bundles and accessories are marked separately.
By default every 6–12 hours for each monitored offer; you can set the range yourself in Settings.
Background price checks work without the product page open. Some sites need a browser – the extension opens them in the background in a separate tab group and closes them after the check.
No. PriceSpark requires a constant internet connection – it checks prices in shops, and the licence is confirmed continuously. After about 2–3 minutes without a connection to the licence server, features are locked and come back on their own once the connection is restored.
Your products, price history and settings are stored locally on your computer. Only licence data goes to the licence server, and only queries about offers go to shops.
Chrome does not let apps install extensions on their own, so you load the PriceSpark extension once, by hand. A wizard in the app guides you through each step and detects by itself when the extension has connected.
Large shops, marketplaces and price comparison sites in Poland, Germany and the Czech Republic, as well as shops found through search engines. You turn shops and markets on and off in the settings.
The licence works on one computer. You can transfer it from your customer account on the website – no more than once every 30 days.
A prepaid monthly subscription – before the period ends you receive a payment link, with no automatic charges – or a one-off licence, for an indefinite period while the service is running.
PriceSpark watches the product, not a single web address. Open a product in Chrome, click the PriceSpark icon (or press Alt+Shift+K) and choose “Find cheaper”. The app recognises the exact product and variant – by EAN code, manufacturer code, brand, model and specifications – and looks for it in shops, price comparison sites and marketplaces. Identical offers are kept apart from other variants, bundles and accessories.
The deal engine compares today’s price with the product’s history – minimum, average and median – instead of trusting “sale” and “−50%” labels. Every product gets a rating: Great, Good, Average or Overpriced.
Search flights, stays and holidays across several sites at once, with results in a single table and the cheapest offer highlighted. Every travel search runs in a new, empty Chrome profile – sites cannot see your history. The subscriptions module compares more than 40 services (streaming, music, audiobooks, cloud storage, VPN, password managers, games, AI tools) with the price shown per month.
