Клев по погоде is a popular Russian-language app for Android devices, which allows you to determine the best times for fishing according to the current weather conditions in your area.

The app gives you the opportunity to find out the fishing locations of different fish species, as well as their average size and weight, and the time of their expected arrival. The app is very useful for those who are planning to go fishing, or who already go fishing and want to know the times of the best days to catch more fish.

The app allows you to set the fishing locations by entering the coordinates, or using the built-in search function. You can also change the time of the first bite and determine the time of the best bite for each fish species. You can also make adjustments to the model, so that it will become more accurate.

To create the database, you need to install the app on your device and enter the necessary data.
