Quell

Quell is a calm, honest place to meet a hard feeling — in about thirty seconds, without an account, a chatbot, or a single piece of tracking. Name what you feel — tension, heaviness, or scattered — then follow one short guided moment chosen for it: a breath, a grounding anchor, a slow sky, a few written words, or simply rest. The ripples calm, the moment is gently noted, and Quell asks one quiet question: did that help? It learns, transparently, what settles you — and tells you the truth, including when something didn't work. WHY QUELL IS DIFFERENT • Nothing leaves your device. No account, no server, no tracking — ever. • No chatbot. No AI that over-validates or fumbles a crisis. Quell never pretends to be a person — it's a calm structure, honestly. • Guidance, not just graphs. It answers "now what?", gently. • A "universe" of light grows from the moments you tend — calm progress you can see, never a guilt-tripping streak. • Honest about itself: a moment usually helps a little, sometimes — and Quell says so, instead of overpromising. CARE, BUILT IN • Always-there help: verified crisis and support lines, one tap away, chosen for your region, with offline fallbacks. • If a feeling keeps getting heavier, Quell gently steps back toward real, human support. • Add a trusted person to reach in a hard moment — stored only on your device. MADE TO FIT YOU • Calm Mode: larger text, fewer words, read-aloud. • Framing that's yours: plain, gentle, or rooted in your own tradition. • Built to work with VoiceOver and Dynamic Type. QUELL DEEP (optional) Quell is always free in the moments that matter. Deep is for the practice that grows around them: every universe style, deeper insight and history, Apple Health, gentle pattern-aware reminders, and ambient soundscapes. • Quell Deep — Monthly: $6.99 per month, auto-renewing subscription. • Quell Deep — Lifetime: $49.99, a one-time purchase (not a subscription). Payment is charged to your Apple Account at confirmation of purchase. The monthly subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel your subscription in your Apple Account settings after purchase. Privacy Policy: https://agezgin.github.io/quell/privacy.html Terms of Use (EULA): https://agezgin.github.io/quell/terms.html Quell is a self-help and awareness tool — not a substitute for diagnosis, treatment, or emergency help. If you are in crisis, contact your local emergency number or a crisis line.

Verdict
The clearest difference is ads: Quell at none against Coach's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.
