Simple Memo is a memo app focused on one thing: launch, write, send. Your memo is sent as an email to a pre-configured address with a single tap. There are no folders, sync settings, or complex features—and with AI Auto-Tagging turned on (Obsidian integration required), tagging happens on device instead of by hand.

What is AI auto-tagging?

Speak or type a note, and AI reads it and adds a title of up to 20 characters, one to three tags describing the content, and a type (todo / idea / log). It works once Obsidian integration is set up and AI Auto-Tagging is turned on in Settings; the note is then appended to your vault with those tags intact, and the email subject gets a short title too. Your original text is never rewritten.

Does AI tagging send my memos to an external server?

No. Tagging and title generation run on your iPhone using Apple's on-device AI (Apple Foundation Models), with no network calls for that step. On devices without Apple Intelligence, on-device lightweight formatting produces a title, tags and a type in the same format.

Can I send memos while offline?

Yes. When you send a memo offline, it's stored in the Outbox—encrypted with AES-GCM on your device. When connectivity is restored, pending memos are sent automatically (automatic retries have a limit; after that, you can resend from History).

Can I use Simple Memo for free?

Yes. The Free plan lets you send up to 3 memos per day, with no time limit—no credit card required, available from day one. If you want to send more, the Premium plan (monthly & yearly) unlocks unlimited sending.

AI ATAKAFounder

An iPhone app that captures voice or typed notes and sends them to email and Obsidian in one tap, with on-device AI auto-tagging of titles and tags.

Overview

A look at simplememofast.com

Simple Memo is a minimal iPhone and Apple Watch app designed for capturing quick thoughts and sending them to your email inbox in one tap. It launches in 0.4 seconds and requires no account setup—just verify your email address and you can start sending memos immediately.

The app includes on-device voice input (iOS 16+), Obsidian integration that automatically appends sent memos to your notes, and on-device AES-GCM encryption for the Outbox and send history. It works offline, storing unsent memos in an encrypted queue that automatically resends when connectivity returns.

A July 2026 update added AI auto-tagging using Apple Foundation Models. With Obsidian integration enabled, the AI reads each memo on your device and adds a title (up to 20 characters), one to three tags, and a type (todo/idea/log) before appending to Obsidian. No data is sent to external servers for tagging.

The free plan allows 3 sends per day with no time limit. Premium plans ($2.99/month or $29.99/year) unlock unlimited sending and the ability to save to Obsidian without emailing.
