SoloPDF vs Lunbi

SoloPDF is a clean, fast, fully local PDF reader — no ads, no account, nothing ever uploaded. • Reading: multiple tabs, outline, page thumbnails, full-text search, fit-width/fit-page zoom. Huge files open instantly thanks to on-demand loading. • Highlights become notes: highlight any text and the annotation is saved as a Markdown notes file (.annotations.md) right next to the PDF — open, edit, and version it with any editor (including our SoloMD). solopdf:// links inside the notes jump straight back to the highlighted passage. • Forms: fill AcroForm PDFs (text fields, checkboxes, dropdowns) and save the result. • Export to Markdown: turn a whole PDF into a Markdown document, outline headings included. • Dark mode with smart page inversion for comfortable night reading. • Interface in English, 简体中文, 繁體中文, and 日本語. Everything runs on your device. No network calls, no data collection.

Read 3 times a week. Exercise twice. Lunbi is a habit tracker that lets you choose your pace and see small actions grow into a world of your own. GOALS THAT FIT REAL LIFE Set how often you want to do each habit: every week, every month, or every two months. Work toward a weekly goal on the days that suit you. Missing a day does not erase the progress you have made this week. ONE TAP, VISIBLE PROGRESS Check off a completed habit with one tap. See how many times you have done it and how close you are to your goal. Keep reading, exercise, study, and other routines together in a simple habit list. A LITTLE WORLD THAT GROWS WITH YOU Your check-ins leave traces in a world of islands, stars, and light. Explore with a small companion, watch your world take shape, and revisit past weeks to see what you have built. • Create and edit your own habits • Choose weekly, monthly, or every-two-month goals • Check in with one tap and follow your progress • Look back on previous weeks • Discover a world that grows with your effort YOUR RECORDS, WITH ICLOUD No separate Lunbi account is required. Habits and check-ins are saved on your device. When iCloud is available, your habits, check-ins, world progress, and selected settings also sync through your private iCloud database across your devices.
