Psalm Song is a complete musical setting of the Book of Psalms: all 150, set to music by Paul Whitehorn, for iPhone, iPad and Apple TV. THE STORY BEHIND THE WORK In ninth grade I was kicked out of school and essentially homeless. I got on my knees and cried out to Jesus, and God heard me from heaven. "This poor man cried, and the LORD heard him, and saved him out of all his troubles" (Psalm 34:6). That day He called me, and I received the Holy Spirit. Since then I have studied the Scriptures in Greek and Hebrew (B.Th., M.Div., and now a PhD in Bible Exposition) and sung the Psalms, in rough recordings for decades. Today's technology finally let me finish them, and God's hand has been on the whole work. I pray they help you memorize the Scripture and see the Psalms as they were meant to be seen: as songs. THE PSALTER IS A SONGBOOK The Psalter is the largest book in Scripture, and for three thousand years it has been the prayer book and hymnbook of God's people. This app returns the Psalms to sound, with the Scripture beside every song, classified according to a structural apparatus drawn from the author's thesis Psalms Are Songs Not Poems. WHAT THESE SONGS ARE These songs are a summary and a commentary on the Psalms, not a word-for-word translation. No song can hold every idea in a psalm. That is why the Scripture is always beside the music: so you can read the psalm itself, in full, while you listen. Psalms 1 to 25 appear in the author's own translation from the Hebrew, paired line by line with the lyrics. Psalms 26 to 150 are shown in the World English Bible. FEATURES All 150 Psalms in six volumes, each with its number and its name Keeps playing: each Psalm rolls into the next, with the app closed or the phone locked Scripture, Lyrics, or both side by side The Hebrew text of every psalm, verse by verse beside the English Lyrics for all 150 songs Ambient mode on Apple TV: the picture fills the screen and each verse appears in English and Hebrew as it is sung Moving backgrounds while you listen: a crackling fireplace, a snowy Christmas town, starry night, seashore, rain and cathedral Psalm videos and a share link for every psalm Playlists for your day: Morning Coffee, While Working, Studying, On the Road, At the Gym, For the Kids, Quiet Time, Sunday Praise, Hard Days, Sleep and more Browse by genre: rock, metal, folk, country, techno, rap, pop, orchestral, ambient, worship and spoken word Make your own playlists Favorites, Recently Played and search across the whole Psalter Daily Psalm of the Day Structural form classification including Cantillated, Didactic, and Composite A complete reading of the author's thesis Personal progress tracking with a learned and unlearned toggle Also on Apple TV, with the Scripture on screen while the music plays THE THESIS, BUILT IN The apparatus that organizes this work is drawn from a thesis arguing that the Psalter contains two functional types. Cantillated psalms are built for communal vocal enactment before God. Didactic psalms are built for instruction directed to the hearer. The full thesis is included in the app, divided into nine readable sections, with audio of the author reading the preface. FOR WHOM THIS APP WAS MADE For pastors, theology students and worship leaders, and for anyone who wants to hear the Psalms sung as God's people have sung them for three thousand years. FREE, ALL OF IT Every Psalm, every playlist and background, the Learn games and the printable workbook are free for everyone, on iPhone, iPad and Apple TV.

Verdict
The clearest difference is update cadence: Psalm Song at every 3 days against Memorix's every 2 months. Memorix's advantage is rating (3.2 vs 3.0) and iOS requirement (15.0 vs 17.0). On price, ratings volume, ads and in-app purchases there is nothing between them.
