I'll develop a mobile application for tracking water, electricity, and

I develop mobile applications for a specific household task — tracking readings from water, electricity, and gas meters with reminders about the deadline for submitting data to the management company. This isn't a universal expense tracker or budget planner: the application is focused on one scenario, and all logic is tailored specifically to it.

The user enters readings for each meter separately — cold water, hot water, electricity, gas — and the application automatically calculates consumption for the period by comparing the new value with the previous one and converts it to cost based on current rates. A separate module handles reminders: I configure notifications to arrive several days before the deadline for submitting readings and repeat on the last available day, so you don't have to pay based on average consumption or a standard rate because you missed the deadline.

Depending on the task, I add photo capture of meter readings, history and consumption charts by month, separate tracking for multiple properties — apartments, dachas, rental properties. The standard package includes:
— input screen for each meter with validation
— automatic consumption and cost calculation
— customizable reminders about submission deadlines
— reading history and reports
— photo capture of readings when needed
