DecompAI helps you focus on one important goal and understand your real daily progress Instead of managing endless tasks, you choose one active goal, write what you did during the day, and let AI analyze whether your actions actually moved you closer DecompAI turns daily reports into clear insights: • Set one focused goal • Add measurable progress when your goal has a number • Write or dictate a daily report • See which tasks affected your goal • Get an AI summary and practical advice • Track daily streaks and goal history • Review your progress in calendar and analytics The app is built for people who want less noise and more clarity. It helps you stay honest with yourself: were you really moving toward the goal, or just staying busy? One goal. Daily focus. Real progress.

Vault Notes

Features
Read full description

Vault Notes is a private notes app built on plain Markdown. Your notes are real .md files stored locally, (and with Pro, in your own Google Drive), not rows in a database we control. We run no servers and never see what you write. WRITE WITHOUT FRICTION Live Markdown editing. Headings, bold, and checklists render as you type. Daily notes are one tap away, so journaling and quick capture stay fast. Banners, callouts, code blocks, footnotes, highlights, and LaTeX math. Paste a link and get a clean preview card. Rename the title to whatever you want. Attach images, PDFs, and GIFs. Read PDFs a page at a time. YOURS, ORGANIZED Folders and subfolders, pinned notes, instant search. Connect notes with [[wikilinks]], or embed one note inside another. Chain notes like chapters with Previous / Next follow-ups. Canvas boards when you need to think spatially. PRIVATE BY DESIGN Public View hides your private notes and images, either on a schedule or with one tap. Hand your phone to someone and don't worry about it. Mark any note or folder Private. Blur the images you'd rather not show. No analytics. No tracking. Nothing phones home. MAKE IT YOURS Features are plugins, so toggle math, callouts, timelines, and image styling as you like. Accent colors that follow you across devices. Apple Pencil sketch notes on iPad. VAULT PRO (optional subscription) Two-way sync between iPhone, iPad, and desktop, all through your own Google Drive. Version history and attachment sync included. Your notes move through your cloud. We never host or read them. Vault Notes is built by one person who uses it every day, and it shows. Download it, write something in it, see if it fits.
