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/
