Focus. Unlock a masterpiece. Opus is a free, unlimited Pomodoro focus timer that turns completed sessions into a museum of your own. Finish a focus session to unlock the next artwork in a curated journey ā a public-domain masterpiece from The Metropolitan Museum of Art or the Cleveland Museum of Art, accompanied by a short museum-style story. FOCUS, THEN DISCOVER Start a session, stay with your work, and leave with something worth keeping. Every completed focus session reveals the next artwork in your journey. The sequence is curated, so your museum grows with purpose rather than at random. CHOOSE YOUR JOURNEY Begin as The Explorer with 15 artworks across 3 wings. Continue as The Curator with 30 artworks across 5 wings, or become The Master Collector with 60 artworks across 8 wings. Watch each room fill as your focus practice grows. THE TIMER IS FREE ā ALWAYS Focus without session limits, locked breaks, ads, or a countdown to a paywall. Choose the rhythm that fits your day: ⢠Classic ā 25/5/15 ⢠Ultra Focus ā 50/10/20 ⢠Quick Study ā 15/3/10 A long break begins automatically after four completed sessions. YOUR MUSEUM Explore unlocked artworks room by room, mark favorites, and read the story behind every piece. Artworks you have not reached remain hidden as silhouettes, so every unlock stays a discovery. TASKS, STREAKS & FOCUS HISTORY Add what you are working on, connect it to a focus session, and see where your time went. Follow your streaks, weekly and monthly charts, and a full year of focus history. QUIET BY DESIGN Warm light and dark themes, a distraction-free Zen Mode, optional completion sounds, and a notification when time is up. No feed. No ads. No noise. FREE & OPUS PRO The unlimited focus timer, tasks, statistics, the Museum, and The Explorer's first wing with 5 artworks are free. Opus Pro unlocks the rest of The Explorer and the complete Curator and Master Collector journeys. PRIVACY No account or sign-up is required. Your sessions, tasks, and collection stay on your device, with full backup export and import. Opus uses anonymous, aggregated usage analytics to improve the experience. Artwork images are delivered from the museums' open-access services, so discovering a new piece requires an internet connection. App languages: English, Turkish, Spanish, German, and French ā including artwork stories. Start your next focus session. Leave with a masterpiece.

Verdict
The clearest difference is update cadence: Nekodo at every 4 days against Opus's every 6 months. Opus's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.0). On price, ads and in-app purchases there is nothing between them.
