Mobilay is an integrated companion service for Mabinogi Mobile, bringing gameplay records, daily tasks, chat, and practical tools together in a desktop app and on the web. It helps players review combat performance, with damage and DPS analysis, battle overlays, saved records, and public rankings for raids and other content. Users can search and compare records by area, target, party, and upload time, or manage personal records and their visibility with Google sign-in.

The service also supports everyday play through account- and character-based daily and weekly task tracking, guild missions, attendance, timers, and inventory and storage tools. Players can search chat history, receive keyword alerts, and view friend, guild, and minimap information. Additional utilities include dye and color assistance, magic resistance and display-limit calculators, and Laynote music tools for editing and previewing MML scores and importing or exporting supported formats.

Mobilay offers settings for themes, notifications, and display preferences, while web sync makes app-collected battle and homework data available online. Windows setup requires Npcap; an Android app is also available.
