About this app

Kairo Timer — the workout timer that just does the job, minus the distractions.

One circuit, one duration, one tap. That's it. No account, no coaching, no distractions. Just a timer built so you can stop thinking about the timer.

FOUR WAYS TO TRAIN

• Ready-made sessions — a 9-minute push-up circuit and an 8-minute abs circuit, written to be followed as they are.
• Starter circuits — classic Tabata, a full time-based circuit, a target-reps circuit. Ready to launch in one tap, and yours to edit or delete.
• Editor — build your own circuit: name, rounds, rest, exercises, target reps or duration. Every detail is yours.
• Smart generator — pick zone, level, duration, equipment, format. The app composes a balanced circuit you can tweak before you start.

THREE EXERCISE MODES

• Time — auto countdown, perfect for HIIT and Tabata.
• Target reps — a fixed number; you confirm when it's done.
• Free reps — you count, you enter, the app keeps track.

BUILT FOR THE EFFORT

• A calm screen to navigate, a battle screen for action: background colors follow the segment (prepare, work, rest, final countdown).
• Demo photos for common exercises: during the workout, tapping "?" opens the sheet with photos and form cues.
• 3-2-1 countdown and segment-start beeps. Haptic feedback.
• A flower mascot cheers you on before you start, halfway through an exercise and before the last one. Four characters to pick from, or none.
• Screen stays on during the workout.
• End-of-session summary: total time, exercises completed, reps logged.
• Session history: look back at your finished or interrupted sessions, with the details of each.

CALENDAR

• See your month at a glance: the days you trained, your Kairo sessions and what you did elsewhere (climbing, a run, the gym), logged in two taps.
• Plan a session on the day you choose — a ready-made session or one of your circuits — and start it when the day comes.

NUTRITION, KEPT SIMPLE

• Track your daily protein and calories: 62 everyday foods counted in portions (an egg, a pot, a slice), plus your own foods.
• Set your goals and see at a glance where you stand, today and over the last 7 days.
• Values come from the Ciqual 2020 table by Anses. They are indicative and do not replace advice from a health professional.

WHAT'S NOT HERE

• No account. No sign-up. No email asked.
• No ads, no data collection. Nothing leaves your phone.
• Your circuits, history, calendar and nutrition log are stored locally only.

WHO IT'S FOR

Home trainers, bodyweight regulars, runners cross-training, HIIT fans — anyone who wants a clean timer without drowning in menus.

Kairo — inspired by the Japanese 回路 (circuit) — is the discipline of emptiness: less noise, more action.

Download, start a Tabata, go.
