Simple Memo vs Obsidian
Which Should You Choose?
Obsidian supports both quick notes and deeper knowledge management, with shortcuts and Quick Capture in 1.14 early access. Simple Memo offers another entry point when you want the same note delivered to your inbox and Obsidian vault. The 0.4-second result measures tap to ready-to-type on an iPhone 16e warm launch.
Obsidian's launch time depends on your plugins and the size of your Vault (we have not measured it). Simple Memo opens only its input screen; in the developer's measurement (iPhone 16e, warm launch) it was ready to type 0.4 seconds after the tap (five runs, 0.366–0.433s).
What is Obsidian?
Obsidian is a Markdown-based Personal Knowledge Management (PKM) tool. Backlinks, graph view, templates, and community plugins help connect notes. Its vault stores local Markdown files, and basic note-taking does not require plugins. More involved knowledge management benefits from understanding Markdown and vault organization. Its iOS app offers capture shortcuts that append without opening the app (1.11+) and a share sheet (1.13+). Native Quick Capture for iOS 26 is described in the 1.14 early access changelog; check current release availability before using it. Obsidian Sync is paid, while iCloud Drive and other sync methods are also available.

3 Fundamental Design Philosophy Differences
-
1
"Knowledge Management" vs "Instant Capture": Fundamentally Different Goals
Obsidian organizes knowledge with backlinks, graph view, and templates, and its shortcuts can also capture a short note. Simple Memo provides another entry point if you want a copy of the same note in both your inbox and vault. -
2
Plugin Ecosystem vs Minimal Setup
Obsidian's community plugins extend the app, but basic notes do not require them. If you use plugins, you manage their selection, settings, and updates, and the configuration can affect launch time. Simple Memo has no plugins. Set your email destination, then choose a vault destination if you also want to send there. -
3
Local File Ownership vs Email Universality
Obsidian stores its vault as local Markdown files. Reading the same vault on another device needs a sync method such as Obsidian Sync (paid) or iCloud Drive. A memo sent by Simple Memo can be read in your inbox on another device; that is a different path from syncing vault files.
Practical PKM Flow with Obsidian + Simple Memo - for Obsidian
Obsidian supports mobile shortcuts, and Quick Capture for iOS 26 is documented in 1.14 early access. When you want a memo in both your vault and email inbox, you can use Simple Memo as an additional entry point.

FAQ
Can Simple Memo write directly to my Obsidian Vault?
Yes. With the Obsidian integration turned on, each memo you send is automatically appended to the note you choose in your own Obsidian vault (no Obsidian account or plugin needed). The same memo also arrives by email, so your inbox keeps a copy (saving to Obsidian only is a Premium feature).
Doesn't Obsidian already have quick capture plugins?
Obsidian's mobile app has capture shortcuts that append to a note without opening the app (1.11+). Its native Quick Capture for iOS 26 is described in the 1.14 early access changelog; check current release availability before using it. Simple Memo was ready to type 0.4 seconds after the tap in our iPhone 16e warm launch test and sends each memo to both your email and Obsidian.
Does Simple Memo have anything like Obsidian's Graph View?
No. Simple Memo is not a PKM tool — it has no graph view, backlinks, or note linking. It serves as the "fast inbox" for your knowledge system. Use Obsidian for building your knowledge graph; use Simple Memo for capturing the raw material that feeds into it.
I'm overwhelmed by Obsidian plugins. Is Simple Memo easier to set up?
The only required setting in Simple Memo is your email address (plus the vault folder and target note if you use the Obsidian integration). There are no plugins or themes to choose, so there is no plugin fatigue.
I'm considering switching from Obsidian to Notion. Is Simple Memo an option?
Simple Memo is not a replacement for Obsidian or Notion — it's a complement. If you need PKM features, keep using Obsidian or Notion. Add Simple Memo for the moments on the move when you want to start typing right away (0.4 seconds after the tap; warm launch, iPhone 16e). Your memos arrive via email and can be imported into any tool.
