Eight tools for a more productive life. One calm, private app. Nothing leaves your device. Your whole life doesn't belong scattered across a dozen apps, each one wanting your email, your data, and another monthly fee. Nestwell brings your planner, wallet, notes, diary, password vault, PDF reader, scanner, and reminders into a single beautifully calm home — every word, number, and secret stored locally on your device, with your vault locked behind a key only you hold. No accounts to create. No profiles to build. WHAT'S INSIDE Planner — Tasks, events and habits in one clear view. Build streaks and watch your consistency grow on a calm monthly calendar. Wallet — Track income, expenses, budgets and savings in any currency on earth, with a built-in calculator so the numbers always add up. Vault — Keep passwords, logins, secure notes and IDs behind a passphrase only you know. Zero-knowledge encryption means no one else can look inside. Notes — A real editor with rich text, tables, checklists, a freehand pen and file attachments — built for depth, not just quick capture. Diary — Write day by day in a warm, paper-style journal made for your eyes only, and keep your streak alive. Reader & Scanner — Open your PDFs in a built-in reader, and turn paper into clean digital documents in seconds. Reminders — Tie a reminder to a note, a diary entry, a vault item, or a plan. Eight tools that truly work as one. PRIVATE BY DESIGN Everything you create stays on your device — nothing is transmitted anywhere unless you choose to. When you choose to back up, every file is encrypted with a passphrase only you know before it ever leaves your phone, so even your backups are yours alone. Send them to iCloud or Google Drive, keep them on local storage, or stay completely device-only. Your vault goes even further — protected in a way that means no one, not even us, could ever look inside. That's Nestwell's promise. MAKE IT YOURS Three premium themes: Nestwell (dark), Paper (light), and Midnight (OLED black), paired with eight accent colors, from jewel tones to quiet neutrals. Available in 21 languages, so it feels like home in yours too. Beautiful on iPhone and iPad. Stop juggling apps. Stop handing over your data. Your private, productive life finally in one calm place.
