Wysa, Calm, Insight Timer and Daylio compared — CBT exercises on demand, breathing sessions, thousands of free meditations and ten-second mood tracking.
No app replaces a therapist, and it is worth saying that before anything else. What these apps do well is cover the gaps between proper support: a breathing exercise at three in the morning, a technique that interrupts a thought loop, or a daily log that slowly reveals which situations line up with your worst days. The four below take distinct roles — an anonymous CBT conversation, produced relaxation sessions, a huge free meditation library, and a one-tap mood diary. The 4 apps in this guide were chosen for those complementary jobs; serious or worsening symptoms belong with a health professional, not a download.
Wysa turns cognitive behavioural therapy into an anonymous chat: concrete reframing, breathing and sleep exercises available at three in the morning.
Wysa is a conversational companion built on cognitive behavioural therapy techniques. You describe how you feel and it walks you through concrete exercises — reframing a spiraling thought, paced breathing, a wind-down routine — rather than offering generic affirmations. Its strongest feature is availability: there is no appointment or waiting list, it can be used anonymously, and three in the morning is exactly when that matters. It is honest about its limits too, and so should you be: it is not a psychologist or a treatment, sessions with a human therapist inside the app are paid, and the scripted conversations become repetitive after weeks of use. It is a first-response tool between real support.
Calm has the most polished breathing and relaxation sessions here — a strong option for slowing down in a concrete moment of overwhelm.
Calm's strength in a mental-health context is the production quality of its short tools: a guided breathing or body-scan session can genuinely slow your pulse during an acute moment of overwhelm, and the app opens to those tools quickly. Underneath sits the category's largest library — guided meditations, sleep stories read by well-known voices, music and soundscapes covering anxiety, stress and rest. It is the best-produced decompression kit here. Most of the catalogue requires a subscription and the annual price is steep, and non-English dubs are inconsistent, so its short free exercises are worth trying before committing. It complements something like Wysa: one de-escalates the moment, one works the thought pattern.
Insight Timer gives you thousands of meditations and talks from real practitioners at no cost, with a timer for meditating without guidance.
Insight Timer is the most generous free option in the group: tens of thousands of guided sessions, music tracks and talks from teachers and professionals cost nothing, and the essentials carry no paywall. A customizable timer supports unguided meditation once you no longer need a voice, which makes it suitable for sustained practice rather than a two-week trial. For anxiety specifically, the breadth means sessions exist for very specific situations — panic, sleep, work stress — without paying to explore them. The weaknesses are the flip side of abundance: navigation can overwhelm at the moment you need calm fastest, quality differs from teacher to teacher, and structured advanced courses require a subscription.
Daylio logs mood and activities with a few taps — no writing — and after a few weeks shows which situations coincide with your worst days.
Daylio is a diary you never have to write in: each day you pick your mood and activities from icons, an entry takes around ten seconds, and reminders keep the streak alive through uneventful weeks. The value shows up after several weeks, when statistics reveal patterns you cannot see day to day — which activities, people or sleep habits tend to coincide with your best and worst stretches. That evidence is genuinely useful for spotting triggers or preparing for a therapy conversation. The free tier limits the number of activities, detailed charts require payment, and tapping icons is no substitute for the nuance of a written journal. As a low-friction tracker that actually gets completed, nothing here is easier.
Download price only. In-app purchases and subscriptions may cost extra.
Questions & answers
Can an app replace a therapist?
No. These apps work as support between sessions — learning specific techniques, keeping a mood log, calming an acute moment — but they do not diagnose or treat anything. If anxiety is interfering with daily life, sleep or work, speak to a health professional. In a crisis, call your local emergency number or a suicide prevention helpline in your country; an app's chat window is not the right response to an emergency.
What is the best free app for anxiety?
Insight Timer is the most generous: thousands of meditations, talks and exercises from professionals at no cost. Wysa also opens a large library of CBT-based exercises for free, keeping sessions with a human therapist for its paid plan. Daylio's core mood tracking is free as well. The pattern is consistent — free tier for tools, payment for human help or structured courses — so you can build real support without subscribing first.
Do these techniques actually work?
The techniques themselves are credible: cognitive behavioural therapy and structured breathing are backed by clinical research when applied properly. What is less certain is how much of that effect survives delivery through an app with no therapist supervising. Used as a complement to real support — or as a low-intensity option during generally fine periods — they help. Used as a replacement for treatment you actually need, they do not.
Is the data I log kept private?
It is a fair question, because mood entries are unusually sensitive data. Wysa can be used anonymously without handing over identity, and Daylio stores entries on the device unless you enable cloud backup. Calm and Insight Timer accounts carry normal cloud trade-offs. As a habit, read the privacy policy of any mental-health app before pouring personal detail into it, and check what gets synced, shared or used for personalization.
