Panic at 3 AM. A racing mind before a presentation. That knot in your chest on Sunday evening. Eftly is for exactly those moments: open the app, tap the SOS button, and a calm voice guides you through — you're tapping along within two seconds. EFT tapping (Emotional Freedom Techniques) is a simple self-help method: while you name what's bothering you, you tap gently with your fingertips on nine acupressure points. Eftly guides every step — the voice tells you what to say and where to tap, the animated figure shows the point, and soft haptics mark the rhythm. You just tap along. WHAT'S INSIDE • 15 guided sessions of 3–4 minutes across six areas: SOS, anxiety, sleep, stress, focus and cravings • Panic SOS and Overwhelm SOS — one tap from the home screen • Sleep sessions for falling asleep, 3 AM wake-ups and pre-sleep worry • Five languages — English, German, Dutch, French, Spanish — every session fully voiced, each language with its own calm, native voice • Gentle tap-rhythm haptics, so you can follow with your eyes closed • Audio keeps playing with the screen locked, with lock-screen controls • Works fully offline, anywhere • A quiet evening reminder, if you want one — no streaks, no guilt PRIVATE BY DESIGN No account, no sign-up, no ads. Your session history stays on your iPhone. The app only sends anonymous usage statistics — and you can switch even that off in Settings. FREE, AND PLUS Five sessions are free forever: both SOS sessions plus one each for anxiety, sleep and stress. Eftly Plus unlocks all 15 sessions in all five languages: € 39.99 a year after a 7-day free trial, or € 8.99 a month (prices may vary by region). Payment is charged to your Apple account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your account settings. A NOTE THAT MATTERS Eftly is a self-help tool, not medical or psychological care. Tapping may help you feel calmer, but it does not diagnose, treat or cure any condition. If you're in crisis, please reach out to a professional — the app links to international helplines.

Verdict
The clearest difference is in-app purchases: Lief App at none against Eftly's 2. Lief App also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). Eftly's advantage is update cadence (every 3 days vs every 5 weeks). On price and ads there is nothing between them.
