Task

I'm a freelancer and I track time every day. I'd tried Toggl, Clockify and Harvest — every time it was the same story: either expensive for basic features, or free but with a UI like a nuclear plant control panel. All I needed was simple: hit Space to start, hit it again to stop, and get an invoice at the end of the month. So I decided to build it myself.

Solution

I did the full product cycle on my own — from design to development. logr is a keyboard-first time tracker: Space to start/stop, Enter to add a client, Escape to close. No modals where they can be avoided.

The stack is deliberately lean — Next.js, React, Supabase for auth and database, Vercel for deployment. For the MVP I kept the schema as simple as possible: a single user_app_state table with JSONB for clients and sessions. Clients → Projects → Tasks with PENDING → ACTIVE → DONE statuses, manual session entry, one-click PDF invoices and CSV export, Google auth with cloud sync, a localStorage fallback for offline work, and dark/light themes.

Dashboard on web and mobile: timer, timeline, projects, billable hours and a daily AI recap

Under the screens sits a small design system: every block — top bar, timer, timeline, projects and tasks, billable hours, goals, activity, daily summary, footer — is a component with desktop and mobile variants and both a filled and an empty state. That is why an empty account does not look like a broken one.

UI kit: components with desktop and mobile variants, filled and empty states

Everything that needs a decision lives in a modal, designed for both breakpoints: manual entry, choosing or creating a project, new client, invoice, settings, inviting a teammate, exporting a report, deletions.

Result

logr is live and fully open-source under Apache 2.0 — I track all my own time exclusively through it, fixing bugs as I hit them. Real-time dogfooding. It's free for anyone to use: found a bug — open an issue, want a feature — PRs welcome.
