Turn focused time into something you can see grow. Lumith helps you make room for study, work, and reading. Choose the apps you want to limit, set aside some time, and let a gem keep you company as you focus on what matters. START NOW. PLAN AHEAD. Choose a duration and hold Focus now as light fills the button with haptic feedback. Or schedule a recurring plan for selected days and times. App blocking requires Screen Time permission and your selection of apps, categories, or websites to limit. UNDERSTAND YOUR APP USAGE Usage Analysis displays usage trends and app rankings for the day you select, using iOS Screen Time reports. Explore a single day, the last 7 days, or the last 30 days with Pro. Rankings always cover the selected day. Reports include system-provided app usage beyond your blocking selection and are available in every role. Data availability and freshness depend on the reports supplied by iOS. CHOOSE HOW YOU COMMIT Normal Mode: Confirm to end early when your plans change. Commitment Mode: Choose reading aloud, Sudoku, or Settling Wait as your exit ritual. Take a moment to reconsider before ending early. These are alternatives; you only complete the ritual you selected. Strict Mode (Pro): Removes the regular early-end option while retaining limited emergency recovery. PAUSE BEFORE YOU STOP Settling Wait: Follow the gem's breathing halo against gentle waves and slowly drifting clouds. Turn on wave audio if you wish. After waiting, decide whether to end, or choose to keep focusing. Read a short commitment aloud before deciding to end. A text alternative is available when reading aloud is impractical or on-device recognition is unavailable. Solve a 6x6 Sudoku using digits 1–6, with no repeats in each row, column, or 2x3 box. A timed alternative is also available. GROW A GEM, ONE SESSION AT A TIME Completed sessions add to your gem's growth. See your progress, current stage, and distance to the next stage. Your selected gem also appears on the app-blocking screen. Some gem content requires Pro; subscriptions do not bypass growth or unlock milestones. SEE YOUR FOCUS HISTORY The focus calendar combines daily focus time and gem thumbnails. Tap a date for details. A 24-hour chart shows the distribution of focus time retained on your device. These views describe your Lumith focus sessions; Usage Analysis describes system-provided app usage. BEGIN WITH FREE FEATURES Normal Mode, Commitment Mode, one focus plan, seven-day usage analysis and focus history details, the daily rhythm chart, and basic gem content are free. Pro adds Strict Mode, more plans, 30-day usage analysis and focus history details, and advanced gem content. PRIVACY, WITH CARE No account is required. Focus records and gem progress stay on your device and are not uploaded to developer servers. App usage is supplied by iOS, displayed on your device, and not uploaded to developer servers. Reading verification uses on-device speech recognition only, with a text alternative when unavailable. Recordings and transcripts are not saved. Loading subscription products, purchasing, and restoring purchases use Apple StoreKit and connect to Apple services. ABOUT PRO Monthly and annual auto-renewable subscriptions are available.

Verdict
The clearest difference is in-app purchases: LED Mobile at none against Lumith's 2. LED Mobile also leads on iOS requirement (9.0 vs 17.0). Lumith's advantage is update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.
