Prayer that fits inside a real day. Ember is a Catholic prayer app built around a practice, not an endless scroll. Arrive with one slow breath. Pray one Scripture-rooted line — with its citation right there. Hold it until it settles. Sixty seconds later, your ember is glowing, and the Word goes with you into the day. THE DAILY PRAYER Begin with the Sign of the Cross and a guided breath. Pray each line slowly — hold to pray, release, amen. Close with the Glory Be. It takes about a minute. It is the minute that changes the other 1,439. ROOTED IN THE WORD 1,260 prayer lines across 14 collections — Trust, Peace, Gratitude, Morning, Beloved, Evening, Hope, Courage, Providence, Mercy, Presence, Charity, Wonder, and Joy. Every line is rooted in Scripture, the Catechism, the saints, or the Church's traditional prayers, and every line carries its citation. Nothing vague, nothing invented, nothing repeated until you have prayed the whole library. THE ROSARY, BEAD BY BEAD Ember knows today's mysteries — Joyful, Sorrowful, Glorious, or Luminous, following the Church's rhythm through the week and the seasons. Pray the full Rosary or a single decade: every prayer written out, every bead counted, the fruit of each mystery held in view. About 20 minutes for the whole crown, 3 for a decade. THE CHURCH'S CLOCK Ember keeps the liturgical calendar: seasons, feasts, and a theme that quietly wears the day's vestment color — violet in Advent and Lent, white in Christmastide and Easter, green through Ordinary Time. One-tap prayer times set reminders at the hours the Church has always prayed: the Morning Offering, the noon Angelus, the three o'clock Hour of Mercy, the Evening Examen. A STREAK THAT STAYS KIND Pray daily and your ember glows brighter. Miss a day and it simply dims, ready to be rekindled — no guilt, no broken chains. Faithfulness, not perfection. ALWAYS WITH YOU • Home Screen and Lock Screen widgets with a real line and its citation • Reminders that carry a whole prayer — worth the glance on its own • Add your own intentions and prayers; they join your feed and daily practice • Favorites, beautiful share cards, and themes that feel like candlelight PRIVATE BY DESIGN Prayer is between you and God. Everything stays on your iPhone: no account, no ads, no analytics, no tracking. Our App Store privacy label is "Data Not Collected," and we intend to keep it that way. FREE. ALL OF IT. FOREVER. The daily prayer, the full Rosary, all fourteen collections, the longer 5- or 7-line prayer, every theme and icon, unlimited prayers in your own words, up to six daily reminders, widgets, and favorites. No subscription, no unlock, no ads — nothing to buy, ever. Prayer should not have a paywall. Begin again. The Lord was already waiting.
