Web Price Alarm - Automatic Monitoring is a useful tool that will help you stay up-to-date with the latest prices of the products you like to buy. The app monitors the websites you select and sends you alerts when there is a price reduction.

You don't have to worry about privacy issues because the app doesn't collect any information about the users. All the data is saved locally on the phone.

There is an option to set rules for notifications. You can get alerts for any product or category of products that you follow. You can choose the time interval for the checks.
