Your heart knows something is off. Maybe it's the scroll that never stops. The mind that won't quiet. The feeling you're drifting from your deen even when you're trying. Qalb is a daily practice for the believing heart — built on Quranic psychology, designed to help you slow down, reflect, and return. — DAILY QURAN REFLECTION Each day, a verse chosen for the inner journey. Not to recite and move on — but to sit with, ponder, and let it speak to what your heart is carrying. — GUIDED DHIKR & MURAQABA Breathe through remembrance sessions grounded in classical tazkiyah. Let dhikr become stillness, not just habit. — HEART JOURNAL (MUHASABAH) A private space to track your inner state. Prompted reflections that ask the real questions: Where is my heart today? What is pulling me away from presence? — SPIRITUAL HABIT TRACKER Build a streak across adhkar, tafakkur, and journaling. Consistency, not perfection — that's the sunnah of the heart. — WHAT QALB IS NOT Not another app fighting for your attention. No infinite feed. No dark patterns. Just a quiet space that's here when you come to it. Made for the Muslim who feels the distance between the life they're living and the heart they want — and is ready to close it, one reflection at a time. — QALB PREMIUM Unlock the full 30-day healing modules, Muhasaba journal, and complete dua library. · Annual plan with 7-day free trial · Monthly plan · Founding Member — one-time lifetime access (limited availability) Subscriptions renew automatically.
