Best Meditation Timer Apps (Insight Timer, Calm, Headspace, Oak)

By Suraj Giri, Productivity Researcher · Updated 2026-05-27

The best meditation timer apps are Insight Timer (largest free library), Calm (premium guided), Headspace (structured courses), Oak (minimalist breath timer), and Smiling Mind (free, education-focused). Choose based on whether you want a simple timer with interval bells, guided sessions, or a full meditation curriculum. For a no-install browser bell, our online timers include meditation modes with interval chimes.

1. Insight Timer

Insight Timer is the largest meditation app by free content, with over 230,000 free guided meditations from teachers around the world. The timer feature itself is excellent: customizable interval bells, ambient sound options, and detailed session statistics. Free tier covers the timer and most guided content; the $5/month Member Plus tier adds courses and offline downloads. Best for self-directed meditators who want a vast free library.

2. Calm

Calm emphasizes production value over selection — fewer meditations but higher polish. Sleep Stories (audio bedtime stories) are a signature feature. Free tier offers a daily meditation; the $70/year Premium unlocks the full library. Best for users who want a comprehensive sleep + meditation app rather than a pure timer.

3. Headspace

Headspace structures meditation as a course curriculum, starting with basics and progressing to specialized topics (anxiety, sleep, focus). Andy Puddicombe’s voice and the consistent course structure make it the easiest entry point for beginners. $70/year. Best for people new to meditation who want guided progression.

4. Oak

A minimalist free app focused on breath and meditation timers with a tiny library of guided practices. The breath timer (box breathing, 4-7-8) is particularly well-designed. No subscription. Best for users who want a simple, no-pressure timer without a content library.

5. Smiling Mind

Australian non-profit offering an entirely free meditation app, with programs designed for adults, students, athletes, and educators. Heavy emphasis on mindfulness curriculum for schools. No paid tier. Best for users who prefer non-profit/educational positioning.

6. Plum Village

The official app of Thich Nhat Hanh’s meditation community, free, with bells and guided practices from the Plum Village tradition. The mindfulness bell timer is excellent — set random intervals for “moments of awareness” throughout the day. Best for users drawn to Buddhist/Zen traditions.

7. Waking Up

Sam Harris’s app, emphasizing the philosophy and theory of meditation alongside guided practice. Substantial intellectual content (essays, conversations with neuroscientists) sets it apart. $100/year. Best for users who want depth beyond the app’s timer.

Comparison Table

What Features Matter in a Meditation Timer?

• Interval bells. Soft chimes at fixed or random intervals during a session, marking time and helping the mind return to focus.
• Custom session length. Anywhere from 1 minute to 2+ hours.
• Ambient sounds. Optional rain, wind, white noise during the session.
• Opening/closing bells. Mark the start and end so the practitioner does not need to glance at a phone.
• Statistics. Streak tracking, total minutes meditated, average session length — useful for habit formation.

Do You Need an App at All?

No. A kitchen timer with a soft bell works. A wristwatch alarm works. Our 10-minute timer works in any browser tab. The apps add curated content (guided sessions), social features (group meditations), and progress tracking, but if you have a personal practice you already know, a simple bell is enough. See our guides on meditation timers for beginners and binaural beats timers for practice-specific setups.
