Sol is a daily notes app designed for the way your days actually unfold. Instead of making you organize everything into folders, notebooks, or complicated systems, Sol gives each day its own space. Capture quick thoughts, meeting notes, tasks, links, images, ideas, and anything else you want to remember, right when it happens. Your notes naturally stay connected to the day they belong to, creating a clear and useful record of your life and work. CAPTURE EVERYTHING IN ONE PLACE Write down a quick thought or create a detailed, structured note. Sol is flexible enough for both. Use it for: • Daily notes and personal logs • Meeting notes and client work • Tasks and reminders • Ideas and inspiration • Links, images, and useful information • Recipes, lists, and plans ORGANIZED BY DAY There is no need to decide where every note belongs. Sol automatically keeps your entries organized by date, so you can focus on capturing what matters instead of managing a filing system. FAST BY DESIGN Sol is built to feel immediate. Create a new entry, start typing, and move on with your day. The interface stays out of your way while still giving you the tools you need to structure your notes. FIND ANYTHING Search across your notes and use hashtags to connect related entries across different days. Turn scattered daily thoughts into an archive that becomes more valuable over time. MORE THAN JUST NOTES Mark entries as tasks, set reminders, add images and links, and organize your day without switching between multiple apps. Sol brings your notes, tasks, and memories together in one calm, chronological space. YOUR DAYS, REMEMBERED Small notes are easy to forget, but together they tell the story of what you worked on, thought about, discovered, and accomplished. Sol helps you capture your days as they happen and return to them whenever you need. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Point the app at your own Worker deployment, and your mail, credentials, and cache stay only between your device and your Cloudflare account — no third-party mail server in between. REQUIRES YOUR OWN BACKEND This is not a general-purpose client for Gmail, iCloud, or other providers. It connects exclusively to a self-hosted agentic-inbox Worker (github.com/cloudflare/agentic-inbox) that you deploy on your own Cloudflare account, authenticated with a Cloudflare Access service token. Deploy the backend first if you haven't already. FEATURES Mailboxes • List, create, switch, and delete mailboxes across your Worker's allowed domains Inbox • Threaded conversation view per folder • Pull-to-refresh and pagination • Swipe to archive or delete, with undo • Multi-select batch actions: mark read/unread, archive, delete Folders • System folders — Inbox, Sent, Drafts, Archive, Spam, Trash • Custom folders — create, rename, delete Conversations • Expandable message threads • Sanitized HTML rendering with remote-image blocking (no tracking pixels) • Star and read toggles, move to folder, attachment support Compose • New messages, reply, reply-all, forward • Drafts save locally and resume exactly where you left off Search • Search-as-you-type with filters for sender, recipient, subject, date range, read/starred status, and attachments • Removable filter chips, infinite scroll Offline • Local cache with optimistic UI, so recent mail stays readable without a connection Built for iPhone and iPad • Adaptive list-detail layout on iPad • Light and dark theme, all standard orientations PRIVACY Agentic Inbox talks only to the Worker URL you configure.
