[Verse 1] Sarah launched her app last Monday, watched a thousand users sign By the weekend half had vanished, left no digital breadcrumb trail behind She needs numbers, needs the metrics, needs to crack the mystery code Why do customers abandon ship along the engagement road? [Chorus] Retention curves will show the way Day one, day seven, day thirty's fate Plot the percentages that stay Cohorts tell the story straight Sticky products bend upward, flat lines spell your doom Retention curves illuminate what happens in each room [Verse 2] Start with cohorts, group your users by the week they first arrived Track their journey through the seasons, see which segments stayed alive Day one's brutal, fifty percent might flee before they see the dawn But the survivors past the first week tend to linger and live on [Chorus] Retention curves will show the way Day one, day seven, day thirty's fate Plot the percentages that stay Cohorts tell the story straight Sticky products bend upward, flat lines spell your doom Retention curves illuminate what happens in each room [Bridge] Good retention curves flatten out Bad ones plummet like a stone Find the cliff where users doubt Make that moment feel like home Feature usage, push notifications A-B testing holds the key Measure, iterate, build foundations For the stickiness you need [Verse 3] Weekly cohorts paint the picture, monthly groups reveal the trend Different colors for each segment, see where loyalty will bend Export data, build the dashboard, visualize the ups and downs Turn raw numbers into wisdom, wear analytics like a crown [Final Chorus] Retention curves will show the way Day one, day seven, day thirty's fate Plot the percentages that stay Cohorts tell the story straight Sticky products bend upward, flat lines spell your doom Retention curves illuminate success in every room [Outro] From the data emerges truth Your product's pulse beats in the graph
