A less familiar programmer who understands this area recommended the site https://captain-droid.com/ru/. Anyone can download and install useful applications and good games on it for free, without registering and sending SMS.
For everyone who likes to travel around Germany, I offer a car rental platform https://my-cab.eu/en/. The website has a very user friendly menu. On this service you can take all types of cars. We take a minivan if we are traveling with the whole family, and when I go alone, I take a sports car or convertible. I recommend this service, I do not overpay on it.
