Competitors shiver.

Horario is the game changer. We're getting close to the system level with Rust to grab the valuable data needed to work for you. That layer is open source — anyone can verify there are no hidden backdoors.

/01

Toggl

A clean, friendly manual timer that plenty of freelancers love. Great when you remember to hit start.

  • →Toggl waits for you to start and stop a timer. Horario tracks itself — no button, no forgotten hours.
  • →Reconstructing a day from memory means rounded, guessed entries. Horario logs the real work as it happens.
  • →Horario knows the project, not just that a timer was running, and turns that into an invoice automatically.
/02

Clockify

A generous free tier and solid team reporting. A capable manual time sheet for organisations.

  • →Most entries are still typed in by hand or nudged along by reminders. Horario needs neither.
  • →Its activity and screenshot add-ons lean into surveillance. Horario keeps raw data on-device — you decide what leaves.
  • →Horario maps time to the actual project and bridges gaps between activities with AI, instead of asking you to fill them in.
/03

RescueTime

Genuinely automatic, and good at showing where your attention went across apps and sites.

  • →It measures which app or website was open — not which client or project that work belonged to.
  • →App-level focus stats don't become billable hours. Horario produces invoices from real, tracked work.
  • →Horario's collection layer is open source (Rust) and on-device, so you can verify there are no hidden backdoors.
