Simple Memo vs OneNote
Which Should You Choose?
OneNote is Microsoft's feature-rich note-taking app, but for quick capture on mobile it's too heavy. Loading notebooks, sections, pages, and OneDrive sync takes 3–6 seconds. Simple Memo is purpose-built for one thing: type a thought in 0.4 seconds and email it to yourself.
I switched from OneNote to Simple Memo after 6 months because my Microsoft account would sign out 2-3 times a month, leaving me unable to take notes at crucial moments — Simple Memo's no-account-needed design eliminated that friction entirely.
What is OneNote?
Microsoft OneNote is a free note-taking app that organizes notes into notebooks, sections, and pages. It features rich text formatting, inking, image embedding, audio recording, and math equations, syncing across devices via OneDrive. It integrates deeply with the Microsoft 365 ecosystem. However, its feature-rich nature makes it slow to launch on mobile, it requires a Microsoft account, and its complex hierarchy is overkill for quickly jotting down a single thought. For users who want to instantly capture an idea and email it to themselves — not organize a digital notebook — OneNote is far more than needed.

5 Structural Differences
-
1
Launch Speed and Memory: Lightweight vs Heavyweight
OneNote takes 3-6 seconds to launch due to notebook structure loading, OneDrive sync, and UI rendering, often consuming 200MB+ of memory. Simple Memo launches in 0.4 seconds with minimal memory footprint, leaving other apps undisturbed in the background. -
2
Notebook Structure vs Flat Email
OneNote's 3-tier hierarchy (Notebook > Section > Page) excels at long-term knowledge organization, but when you just need to jot down a quick thought, deciding "which notebook, which section" creates cognitive load. Simple Memo sends flat emails. Organize later in your inbox. -
3
Microsoft 365 Dependency: Zero vs Deep Integration
OneNote requires a Microsoft account and integrates deeply with OneDrive, Teams, Outlook, and Word. Great for Microsoft 365 users, but ecosystem lock-in for everyone else. Simple Memo needs no Microsoft account — it operates on email, the universal protocol. -
4
Mobile Experience: Purpose-Built vs Desktop Port
OneNote's mobile app condenses the desktop experience into a small screen, cramming notebook/section/page navigation into limited space. Simple Memo is mobile-first: a single-screen app where "write and send" completes with just your thumb. -
5
Data Portability: Email vs OneDrive
OneNote data lives in a proprietary format on OneDrive — exporting requires conversion to PDF or Word. Simple Memo data arrives as email, viewable, searchable, and forwardable from Gmail, Outlook, Apple Mail, or any platform. Email is the most portable data format that exists.
Who Should Choose Which?
- Need to capture ideas instantly
- Find OneNote's mobile launch too slow
- Don't want to use a Microsoft account
- Want memos delivered to your email inbox
- Prioritize speed and simplicity above all
- Don't want ecosystem lock-in
- Organize notes long-term in notebooks
- Use inking or hand-drawn diagrams
- Need Microsoft 365 integration
- Share notebooks with a team
- Need rich text and image embedding
- Already invested in the Microsoft ecosystem
Using Simple Memo - for Obsidian in a Microsoft 365 Environment
For Microsoft 365 users, OneNote is a natural choice. Its integration with Teams, Outlook, and SharePoint is powerful. However, OneNote's mobile app takes 3-6 seconds to launch, and Microsoft account session expiration can suddenly block access.
The key advantage of Simple Memo in a Microsoft 365 environment is setting your Outlook email as the destination. Memos captured on the go arrive in your Outlook inbox within seconds. Back at your desk, one click copies the content into OneNote. Using Outlook Rules, you can auto-sort Simple Memo emails into a dedicated folder. Since it's independent of Microsoft account authentication, you can always capture memos even when session issues occur.
FAQ
Is there a lighter alternative to OneNote for mobile note capture?
OneNote's mobile app takes 3-6 seconds to launch. For the specific use case of "quickly jot and email," Simple Memo launches in 0.4 seconds. It's not a OneNote replacement but the fastest mobile capture companion you can pair with OneNote.
How do I forward a OneNote page to Outlook email?
OneNote requires manual sharing via the share menu. Simple Memo sends memos to any email address with one tap with one tap — not just Outlook, but Gmail, Apple Mail, or any email service.
Can Microsoft account sign-out prevent me from taking notes?
Yes — OneNote session expiration can temporarily block note sync or creation. Simple Memo requires no account at all, so sign-out issues simply don't exist. You can always capture a memo, anytime.
OneNote notebook organization feels overwhelming. Does Simple Memo require organizing?
Simple Memo has zero organization features. Memos are sent as emails, and organization happens in your email client (folders, labels, search). No in-app sorting or filing — the biggest operational difference from OneNote.
What's the best workflow combining OneNote and Simple Memo?
Capture fleeting thoughts with Simple Memo during commutes or meetings (instant email delivery), then organize them into OneNote notebooks at your desk. Simple Memo handles capture speed; OneNote handles organizational depth.
