Product comparator

Narrowed down your selection to few products and still can’t decide which one to buy? The application will let you easily compare your pre-selected products and pick the winner based on evaluation of particular features.

  1. Our unique overall product score will help you very quickly find out which of the candidates is the best valued.
  2. If score is not enough, you can still go over all the features and carefully compare achieved results for every product.
  3. Every score contains number of opinions, which participated on the feature evaluation.

Score favours fresh opinions

Our unique overall product score is aware of the review’s age. Study shows that as much as 85 % participants ignore reviews older than 3 months.

  1. Our unique algorithm, among other things, naturally decreases overall score of the product, in case there are no new reviews. The reason is, couple of years old smartphone’s display usually can’t stand up to new ones, even though it was the best one at the time. 
  2. When searching or comparing, more emphais is put on new reviews rather than old ones.
  3. Ageing products are naturally pushed down into background, despite they have been the top in the segment at their times.
