Opus vs NanaiNest

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 — 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 — ALWAYS Focus without session limits, locked breaks, ads, or a countdown to a paywall. Choose the rhythm that fits your day: • Classic — 25/5/15 • Ultra Focus — 50/10/20 • Quick Study — 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 — including artwork stories. Start your next focus session. Leave with a masterpiece.

NanaiNest turns focus time into something you look forward to. Choose a living ambient world, mix soothing sounds, and let a primordial egg grow while you study, work, or unwind — then hatch it, collect its holographic card, and uncover the lore behind it. AMBIENT WORLDS Handcrafted atmospheric scenes with looping video backgrounds — from a crackling bonfire to moonlit ruins — each designed to pull you into a calm state of flow. PRIMORDIAL EGGS Pick an egg and keep it near while you focus. Your session feeds it energy. When it's ready, a hatching ceremony reveals a living, audio-reactive sphere. HOLO CARD COLLECTION & LORE Every hatch earns a holographic 3D collectible card. Hatch every variant of an egg to unlock its Lore Card — a piece of the world's story, revealed layer by layer. SOUND & MUSIC Mix rain, fire, forest and more. Play the built-in lo-fi library or live radio, with lock screen and AirPods controls. REACTIVE SPHERES Sphere visualizers react to your music — or to the real world through the microphone (nothing is ever recorded or transmitted). FOCUS TOOLS Pomodoro timer, to-do list, and multi-tab notes — everything for a study session in one place. YOUR NEST, SAFE Sign in with Apple or email to keep your eggs and cards synced. Free — no ads, no purchases.
