How much does it cost to develop the next app for Android?

Question

Android

Good afternoon!
Help estimate the cost of developing the following application:
- the application must connect via Bluetooth to a certain device
- this device transmits some characteristics taken from the soil
- the essence of the work is as follows: a person with a device and an application (spinning on a phone, for example) walks around a certain area and takes pictures data
- the application catches this data via a Bluetooth channel and stores it in a database + remembers at what point this data was taken via GPS
- all this is displayed on the screen online
- this way data collection sessions are obtained (for example, filmed in one place - saved; filmed in another; and so on)
- then in offline mode (for example, in the office after measurements), the data can be displayed in two ways: build tables and graphs and how the characteristics changed
- and display information on the map in the form of collection points, when you click on a point, data taken at this point should be displayed
B the cost should include UI design, engineering, development and testing.
Thank you!

The cost of development is calculated by the formula time * hourly rate. These two parameters are different for all developers.
Therefore, take your TK, go to any freelance exchange and ask the developers to immediately give an assessment.
