Captioo vs Simple Memo - for Obsidian
For people who want to email themselves, the Captio way
If you searched for "Captio" on the App Store and saw both Captioo and "Simple Memo - for Obsidian" side by side, this article is for you. Captio, Captioo, and Simple Memo are three separate apps. Here is what each is, and how to choose.
Captio, Captioo, and Simple Memo - for Obsidian are three separate apps. Simple Memo is not the official successor to Captio and is unrelated to Captioo (808 inc.). Captioo leans toward more features (image, widgets) and is free; Simple Memo focuses narrowly on "type and email it to yourself."
First: Captio, Captioo, and Simple Memo - for Obsidian are all different apps
The original Captio was a focused iPhone app for one thing: launch, type, and send the note to your own email. Not a note organizer — a way to flush ideas into your inbox before you forgot them. People who loved that lightness still miss it.
Today, when you search "Captio" on the App Store or on Google, you may see Captioo and Simple Memo - for Obsidian appear together. The names are similar, but these are three separate apps:
- Captio: A former iPhone app that sent memos to your own email. No longer available on the App Store.
- Captioo: An app from a different developer (808 inc.), available on App Store and Google Play.
- Simple Memo - for Obsidian: This site's app. An independent iPhone app inspired by Captio's workflow.
Simple Memo is unrelated to Captio and its developer, Captioo, 808 inc., and Emburse Captio. Simple Memo is not an official successor to Captio. It is an independent app inspired by the "write and email it to yourself" workflow that made Captio loved.
What is Captioo
Captioo is an app on the App Store and Google Play for sending memos and ideas to your own email. According to its public store description, it offers:
- One-tap memo to email
- Image sending
- Widget support
- Sharing from Safari and Chrome
- Free to use
If a free price tag, image sending, or sharing features matter to you, Captioo may be a good fit. When choosing an app, factors like "how do ads sit with me," "how simple is it to actually use," and "how close to Captio's minimal flow does it feel" also matter — and these depend on personal preference.

What is Simple Memo - for Obsidian
Simple Memo is an iPhone app focused on one thing: writing a memo and sending it straight to your own email inbox. The flow is small:
- Open the app
- Write the memo
- Send it to your email
It is not for foldering, tagging, or managing notes as a database. It only does one thing — get the thought into your inbox before it disappears. Simple Memo is not a replacement for Apple Notes, Notion, Drafts, Todoist, or Things. It sits one step before them: the first place a fleeting idea lands, before you ever decide where it really belongs.

If you miss Captio's feel

- Fast to send
- It shows up in your inbox afterwards
- You don't have to manage notes inside the app
Simple Memo leans toward that. It is not a replacement for Captioo, Drafts, Apple Notes, Notion, Todoist, or Things. It sits one step earlier — the first place a thought lands.
