A Pomodoro-style focus timer that doesn’t stop on the Lock Screen or Dynamic Island. Close the app and the remaining time still follows you, along with today’s goal and your history. Focus in the timer, routine in the plan Build focus, short break, and long break in any order. Adjust durations in Settings and see the current session on Home. When a session ends, the next one starts naturally. Focus that continues on Lock Screen Live Activity shows remaining time and whether you’re focusing or on a break. Controls stay in the app; the Lock Screen keeps the flow visible. You can turn Live Activity off in Settings. Daily goals and reports Track a daily focus goal and a weekly summary on Home. The Report tab shows day, week, and month patterns, plus charts and focus/break totals. Export and iCloud Export CSV or a monthly PDF from Settings. iCloud sync is off by default.

Lumo is a browser for phones, tablets and foldables. On a tablet or an unfolded foldable, pages load as their full desktop versions — the whole site, not a phone layout. On a phone, pages load in their mobile versions and fill the screen, with the controls where your thumb is. Beside the page is an assistant that has already read it: ask it something, or have it do the work. AT HOME ON EVERY SCREEN · Tablet and unfolded foldable: a sidebar beside the page, a toolbar on top, side panels and two pages side by side · Phone and folded foldable: the address bar and buttons at the bottom, a sidebar that slides out from the left edge, panels that rise from below · Fold or unfold and the layout follows without reloading the page · Choose the desktop or mobile version for any single site, on that device only · Right-click menus, link hover, keyboard shortcuts; trackpad and mouse scrolling ride the system's own path · Per-site zoom, appearance, fonts, camera and microphone permissions, remembered for each site A NEW START PAGE · Pure white or pure black, with your search field and favorite sites · An optional character-art background — fish, spaceships, or two people who meet and walk on hand in hand — drawn on your device with no network access AN ASSISTANT BESIDE THE PAGE · It has read the page before you open it · Ask in your own language about a page in another, and the lines it found light up · What is not on the page, it says is not on the page · Say what you want done: export a PDF or a long screenshot, download an image, save a table, open and close tabs, put two pages side by side, write a note · Answers can come as charts, tables and cards · Bring your own key, or sign in with a subscription you already have. Lumo has no server; questions do not pass through us. · Part of Lumo Pro SPACES · Each Space owns its tabs and pinned sites, color-coded and a swipe apart · Pages you use stay alive; when the system needs memory back, tabs keep their address and scroll position · Closing a tab or clearing a whole Space can be undone PINNED SITES AND FOLDERS · Everyday sites in a grid; the rest in folders within folders, arranged by dragging · Rename any of them WEB EXTENSIONS · Compatible Web Extensions from extension stores or files you have; pin three to the toolbar. Browsing the store is free; installing needs Lumo Pro. AD AND TRACKER BLOCKING · Engine-level rules stop requests before they download — faster, lighter pages · Third-party requests only, so sign-ins keep working; one switch, or allow a single site NOTES, TRANSLATION, PASSWORDS · A notes panel beside the page, synced to your other devices · Select text to translate it; in a text field, replace the original · Passwords in the system's secure storage, filled after you unlock; backups encrypted with a passphrase only you know ALSO · PDFs, downloads, temporary link previews, history by date with search and delete, your own background, several app icons, light and dark LUMO PRO (lifetime purchase or auto-renewable subscription — buy once, use it on all your devices) · Web extensions, the translation lens (whole-page translation is free) and the assistant · Page markup with a pen or a finger, kept for when the page comes back · Media grid for every picture and video in one or several tabs · Video speed and picture in picture for any site, with ambient light · Professional Web Toolkit: extract images, links, tables and videos; inspect resources and storage; export PDFs and long screenshots; custom CSS per site · User scripts, sessions, page monitors, avatar ornaments, daylight and a daily line Browsing history stays on your device.

Verdict
The clearest difference is in-app purchases: Lock at none against Lumo Browser's 3. Lumo Browser's advantage is update cadence (every 2 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
