I'll develop a mobile app—family budget with user roles

I specialize in developing mobile apps for those tired of keeping their family budget in a notebook or scattered spreadsheets. My specialty is specifically joint budgets: an app where several family members add their expenses to one common pool, rather than keeping accounts separately. Husband, wife, adult children—each adds their expenses in real time, and the whole family sees the current picture, not a summary from a week ago.

At the core of the app is a flexible system of limits by category: groceries, transport, entertainment, utilities. The family agrees on boundaries in advance, and the app itself sends a notification when a category limit is running out. A separate role system is thought through: some participants have the right to edit the budget and change limits, others—only view the figures without interfering. This is convenient when you need to show the budget to a teenager or relative but not give them the ability to change anything.

I take the project end-to-end—from working out screens and role logic to a finished app for iOS and Android, with clear reports and transaction history. I work in stages with intermediate demonstrations so the result matches expectations.

— Shared budget with contribution from each participant
— Category limits and overage notifications
— Roles: editor and observer
— Reports and expense history
