Captio Shut Down: What Happened & What to Use Now

The End of an Era: Captio's Shutdown

Captio was remarkable. It did one thing exceptionally well: let you email yourself a note in a few taps. Launched in 2010, it became a favorite among productivity enthusiasts and anyone who valued speed and simplicity.

The app's simplicity was its strength -- no unnecessary features, no distracting UI elements, just a text field and a send button. For years, many users relied on Captio as their preferred way to capture fleeting thoughts and send them directly to their inbox.

Why Did Captio Shut Down?

In the farewell notice on captio.co, the developer announced that Captio's cloud service would end on October 1, 2024, and gave the reason: he could no longer dedicate the resources needed to keep the app stable and secure. The notice also says Captio had left the App Store about two years earlier, and suggests searching the App Store for "email yourself" to find apps with similar functionality.

Because Captio sent every note as an email, the notes users sent remain in their own mailboxes; only new sending stopped.

What Made Captio Special?

If you used Captio, you know what made it irreplaceable for many workflows:

• Fast capture: Open the app, type, tap send
• Little friction: A text field and a send button, nothing else to organize
• Email delivery: Notes landed in your own inbox
• Beautiful minimalism: The interface was almost invisible -- pure functionality
• Email integration: Worked as part of a larger email-based workflow

Captio's shutdown left a gap. Former users looking for a replacement found that each alternative makes different trade-offs.

The Top 5 Captio Alternatives for 2026

1. Simple Memo - for Obsidian: The Same Open-Type-Send Flow

If you want Captio's open-type-send flow, Simple Memo - for Obsidian is built around it. It was built by a solo developer who had used Captio for years, with the same focus on speed and simplicity. It is an independent app, not a continuation of Captio.

Why it suits former Captio users:

• Ready to type 0.4 seconds after the tap (warm launch, iPhone 16e, median of 5)
• Same core concept: one button to email yourself a note
• Home Screen and Lock Screen widget (iOS 17+) and a Control Center / Lock Screen control (iOS 18+) that open the app with one tap; voice input starts right away on iOS 26+ with a supported device and language
• Beautiful dark theme that feels natural on modern iPhones
• No ads, no unnecessary features
• Voice-to-text support for hands-free capture
• Active development with regular improvements

Considerations:

• Narrowly focused on email-to-self (not for traditional note-taking)
• Requires internet for email delivery
• Subscription pricing (free tier: 3 sends/day; Premium: $2.99/mo or $29.99/yr) versus Captio's one-time purchase

Verdict: If you want a Captio-style workflow on a current iPhone, Simple Memo is inspired by that workflow and adds features that use modern iOS capabilities.

2. Note to Self Mail

A purpose-built app specifically for emailing yourself notes, "Note to Self Mail" is another strong alternative; it has been on the App Store since 2016.

Advantages:

• Built for quick notes to your inbox
• Clean, simple interface
• Free, with a one-time Pro upgrade ($4.99 in the US App Store, September 2026) for attachments, sketches, audio notes and scanning
• Multiple recipient addresses, and it can send through your own email account

Disadvantages:

• Last updated in October 2024 (as of September 2026)
• Less polished UI compared to Captio
• Attachments, audio notes and sketches require Pro

3. Email Me (now “Audio Notes | Email Me”)

Another email-to-self focused app that provides a Captio-like experience with some additional features.

Advantages:

• Audio notes with on-device transcription
• Supports multiple email addresses
• Email history within the app
• Offline mode (saves locally until connectivity returns)

Disadvantages:

• More complex than Captio (additional features = more UI)
• Unlimited sending requires a subscription or lifetime purchase

4. Drafts

While not specifically built for email-to-self, Drafts is a powerful text capture app that can handle Captio's use case while offering far more flexibility.

Advantages:

• Fast to start typing (0.9 seconds at best in our warm-launch measurement; median 1.45 seconds)
• Powerful automation and scripting
• Can send emails, but also has 50+ other actions
• Excellent for complex workflows
• Active development and strong community

Disadvantages:

• More complex than Captio (feature-rich can mean more friction)
• Drafts Pro subscription required for full functionality ($1.99/month or $19.99/year)
• Overkill if you only need email-to-self
• Steeper learning curve

Best for: Users who captured notes via email but also used other workflows. Anyone who wants automation power alongside speed.

5. Apple Mail with Shortcuts

The free, no-app-required solution. You can create a Siri Shortcut that accomplishes the same thing Captio did, using Apple's native Mail app.

Advantages:

• No app to install
• Uses your existing email account
• Completely free
• Customizable to your exact needs

Disadvantages:

• Requires setup time to create the shortcut
• Less elegant user experience
• Runs can be interrupted by permissions, Mail account setup or a locked device

Best for: Users who want a free option and don't mind building and maintaining their own shortcut.

Quick Comparison Table

How to Migrate From Captio

If you're looking to switch from Captio now that it's gone, here's how to make the transition:

Step 1: Choose Your Replacement

Use the comparison above to pick which app best matches your needs. If you want the closest open-type-send flow, Simple Memo. If you want a free app with a one-time Pro upgrade, Note to Self Mail. If you want the most automation, Drafts.

Step 2: Set Up Email Configuration

Most of these apps require you to configure your email address once. Simple Memo asks for it the first time you send a memo and confirms it with a code (you can also set it first in Settings).

Step 3: Create a Shortcut (Optional)

For quick access, add a Lock Screen shortcut or a Home Screen icon. Simple Memo has its own Home Screen and Lock Screen widget (iOS 17 and later), plus a Control Center / Lock Screen control (iOS 18 and later).

Step 4: Delete the Captio App

Since Captio is no longer updated, you can safely remove it from your iPhone. It won't break anything, but you also won't get any support if issues arise with future iOS versions.

What Captio Users Should Know

If you were deeply invested in Captio's ecosystem, you might be wondering about migrating old notes. Unfortunately, there's no direct data migration because Captio notes were stored in your email inbox, not within the app. The good news: all your old Captio emails are still in your inbox. The bad news: you'll need to migrate them manually if you want them in a new note app.

Final Recommendation

If you loved Captio for its speed and simplicity, Simple Memo keeps its open-type-send flow. It is an independent app inspired by Captio's workflow, not a continuation of Captio.

If you loved Captio's integration with email but also want more features, Drafts provides excellent speed with automation power.

If you want a free option, Note to Self Mail covers the basics for free, with a one-time Pro upgrade for attachments, audio notes, sketches and scanning.

What matters most is that you have options now. The quick-capture email-to-self ecosystem is alive and well in 2026, with several good options on current iOS.
