Idea Vault is a clean, distraction free space to capture ideas the moment they strike and organize them your way. WRITE FREELY A minimal editor with real formatting: bold, italic, underline, headings, and bullet lists — plus undo and redo, so you can write without worrying about a mistake. Start faster with built in templates for meeting notes, journal entries, and to do lists, or begin from a blank page. STAY ORGANIZED Tag notes, add a mood, drop a location, and color code anything that matters. Search finds what you need instantly — by title, body, tag, mood, or location — and quick filter chips jump you straight to favorites, encrypted notes, or any tag. Sort however you think: newest first, oldest first, alphabetical, or favorites first. YOUR NOTES, PROTECTED Lock individual notes with on device AES 256 encryption, or encrypt everything at once. Protect the whole vault with Face ID or your device passcode. Nothing leaves your device unless you choose to share it. SHARE ON YOUR TERMS Export any note as rich text or plain text and send it wherever you need it, or back up your entire vault at once from Settings. STAY ON TRACK Turn on a daily reminder so a good idea never slips away. Idea Vault is free to use, with optional ads you can remove forever with a single one time purchase. No subscriptions, no accounts, no clutter. Just a fast, private place for your best ideas.

Verdict
The clearest difference is ads: Ounie at none against Idea Vault's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.
