Mobile Time-Tracking ios and android App

Job ID: 40134605

Budget: $250 – $750 USD

I need a developer who can build a mobile-first, browser-based application that lets users organise their schedules, log tasks, and track work vs. break time from a clean, intuitive interface. The core of the tool is a calendar that supports simple colour-coded events; beyond that, I want a straightforward task list, a running timer for each task, and automatic push notifications so users never miss an upcoming block of work or a scheduled pause.

Because the app must feel seamless on mobile browsers, responsive design and lightweight front-end performance are essential. I’m happy for you to choose the stack—React, Vue, Svelte, or something comparable—as long as it remains maintainable and easy to extend. A modest back end (Node, Firebase, Supabase, etc.) can store user data and notification schedules.

Please show links to any productivity or scheduling projects you’ve shipped before, outline your proposed tech stack, estimate how long the build will take, and provide a cost breakdown or milestone plan.

Deliverables:
• Mobile-optimised web application with task timer, basic colour-coded calendar, and push notification engine
• Clean, modern UI/UX with touch-friendly controls
• Admin or settings panel for managing colour choices, time formats, and notification preferences
• Deployment instructions and concise technical documentation

I’ll review portfolios on a rolling basis and aim to select a developer shortly, so include your best examples and a realistic timeline.
