Why Performance Matters More Than Feature Lists
When you search for a note-taking app for your Mac, most guides throw a feature grid at you: markdown support, backlinks, AI writing, folder nesting. Those lists matter — until your MacBook Air fan spins up during a video call because you left Notion open in the background.
The hidden variable in every note-taking app is its underlying architecture. Many of the most popular apps are built on Electron, a framework that wraps a web app inside a native window. On Apple Silicon Macs, Electron apps carry a 2–3x memory footprint compared to apps compiled as Universal 2 native binaries. For users on an 8 GB MacBook Air — still Apple's most-shipped laptop configuration — that overhead translates directly into battery drain, swap pressure, and a sluggish multitasking experience.
This guide does not rank apps by feature count. It ranks them by how they actually run on M-series hardware. We benchmarked eight apps over 30 days on a MacBook Air M3 and a Mac Studio M2, measuring three metrics that matter more than any bullet list: cold-launch time (open-to-typing), idle RAM usage, and battery drain per hour during continuous editing. If you are on an 8 GB Mac or you simply value a responsive, cool-running machine, the results may change how you think about your note-taking stack.
How We Tested: Hardware, Metrics, and Methodology
All benchmarks were collected by Atlas Workspace over a 30-day period using two machines: a MacBook Air M3 (8 GB RAM, macOS 15.4) and a Mac Studio M2 (32 GB RAM, macOS 15.4). Each app was tested in isolation — no other applications running except the system processes — to isolate its footprint.
Three Core Metrics
- Cold-launch time (open-to-typing): The time from clicking the app icon until the first keystroke registers in a new note. This captures splash screens, plugin initialization, and sync warm-up — not just the window appearing.
- Idle RAM usage: Resident memory after opening the app, loading a typical notes database (approximately 500 notes), and letting it sit untouched for five minutes. This reflects what the app costs you while it is open but not actively used.
- Battery drain per hour: Percentage of battery consumed during one hour of continuous typing and editing on the MacBook Air M3, with screen brightness fixed at 70%. This is the metric that most directly affects real-world usability on a laptop.

Tier 1: Lightweight Native Apps
These apps are compiled as Universal 2 Apple Silicon binaries. They launch instantly, sip RAM, and barely register on the battery graph. If you own an 8 GB MacBook Air, this is the tier you should live in.
| App | Architecture | Cold-Launch Time | Idle RAM | Battery Drain / Hr |
|---|---|---|---|---|
| Apple Notes | Universal 2 (Native) | 0.4 seconds | 142 MB | ~3.5% |
| Bear | Universal 2 (Native) | 0.7 seconds | 84 MB | ~3.0% |
| Drafts | Universal 2 (Native) | 0.5 seconds | ~90 MB (est.) | 2.1% |
| Craft | Universal 2 (Native) | 1.1 seconds | ~180 MB (est.) | ~4.0% |
Apple Notes — 0.4 Seconds to First Keystroke
Apple Notes is the fastest app in the test by a meaningful margin. It opens in 0.4 seconds and idles at 142 MB of RAM. Its iCloud sync latency averaged 1.4 seconds — the lowest of any syncing app tested. For users who simply need to capture and retrieve text across Apple devices, there is no performance argument against it. The tradeoff is feature depth: no backlinks, no markdown, no plugin ecosystem. But if raw speed is your priority, Apple Notes is the benchmark.
Bear — 84 MB Idle, the Lightest App in the Test
Bear's 84 MB idle RAM is the lowest of any app tested — roughly one-quarter of Notion's footprint and one-sixth of Obsidian's. It opens in 0.7 seconds and supports markdown with a clean, distraction-free editor. Bear is a native macOS app through and through, and it shows in every interaction. The catch: Bear is iOS/macOS only, and its free version limits you to one device. The Bear Pro subscription ($2.99/month) unlocks cross-device sync and themes.
Drafts — 2.1% Battery Drain per Hour, the Lightest of All
Drafts is not a full note-taking app in the traditional sense — it is a capture inbox that can forward text to other destinations. But for the specific use case of quick capture, it is the most battery-efficient app in this comparison at 2.1% per hour. It opens in 0.5 seconds and its architecture is fully native. If you pair Drafts with a backend like Apple Notes or Bear, you get the fastest possible capture experience with minimal system impact.
Craft — Native Polish with a Slightly Larger Footprint
Craft is also a Universal 2 binary, but its rich card-based editor and inline media support push its idle RAM higher than Bear or Apple Notes — roughly 180 MB in testing. Its cold-launch time of 1.1 seconds is still excellent, and its battery drain is moderate. Craft is the best choice in Tier 1 if you want a visually polished, block-based editor without leaving the native performance envelope.
Tier 2: Medium Native / Electron-Tuned Apps
These apps use Electron but with varying degrees of Apple Silicon tuning. They are heavier than Tier 1 apps but still usable on 16 GB Macs. On 8 GB machines, they are workable if you do not keep them running constantly.
| App | Architecture | Cold-Launch Time | Idle RAM | Battery Drain / Hr |
|---|---|---|---|---|
| Obsidian | Electron (tuned) | 1.3 seconds (+ plugin warm-up) | 478 MB | ~6.5% |
| Logseq | Electron (tuned) | ~1.5 seconds | ~350 MB (est.) | ~5.5% |
| Reflect | Electron (tuned) | ~1.2 seconds | ~280 MB (est.) | ~5.0% |
Obsidian — Powerful but RAM-Hungry
Obsidian is the most capable app in this tier, with a vast plugin ecosystem and local-first markdown storage. But that power comes at a cost: 478 MB of idle RAM and a cold-launch time of 1.3 seconds that increases further if you have many community plugins enabled. The plugin warm-up phase — where Obsidian loads and initializes each plugin — can add another 2–3 seconds before the app is fully responsive. On an 8 GB MacBook Air, Obsidian is usable if you open it only when you need it and close it when you are done. Leaving it running in the background will consume nearly half a gigabyte of memory that your system could use for other tasks.
Logseq and Reflect — Lighter Electron Alternatives
Logseq and Reflect use Electron but with better Apple Silicon tuning than Notion or Evernote. Their idle RAM is lower than Obsidian's, and their launch times are competitive. Logseq is a strong choice for users who want an outliner-style knowledge graph without Obsidian's plugin overhead. Reflect offers a polished, Roam-like experience with end-to-end encryption. Both are viable on 16 GB Macs and acceptable on 8 GB machines if you treat them as session-based tools rather than always-on apps.
Tier 3: Heavy Electron Apps
These are the apps that make your MacBook Air warm. They are Electron wrappers with minimal Apple Silicon optimization, carrying 2–3x the memory footprint of native apps. They are functional and feature-rich, but they demand a hardware budget that many MacBook Air users do not have.
| App | Architecture | Cold-Launch Time | Idle RAM | Battery Drain / Hr |
|---|---|---|---|---|
| Notion | Electron (unoptimized) | 2.6–2.7 seconds | 312 MB | 12.4% |
| Evernote | Electron (unoptimized) | ~2.5 seconds | ~350 MB (est.) | ~10% |
| OneNote | Electron (unoptimized) | ~2.0 seconds | ~280 MB (est.) | ~8% |
Notion — 12.4% Battery Drain per Hour
Notion is the heaviest app in this comparison. Its 2.6–2.7 second cold-launch time is the slowest of any app tested, and its 312 MB idle RAM is more than double Apple Notes. But the most striking figure is battery drain: 12.4% per hour during continuous editing. Over a four-hour work session, that is nearly 50% of your battery — just for taking notes. On an 8 GB MacBook Air, leaving Notion running in the background is a measurable drain on both battery and system responsiveness.
None of this means Notion is a bad app. Its database, wiki, and project management features are unmatched in this lineup. But it is a tool designed for a desktop with abundant RAM and a power supply nearby. If you use a MacBook Air as your primary machine, Notion is best treated as a browser-based tool that you open when needed and close when done.
Evernote and OneNote — Legacy Electron Ports
Evernote and OneNote are both Electron apps that have not received the same level of Apple Silicon tuning as Tier 2 apps. Their launch times and RAM usage are comparable to Notion's, though their battery drain is slightly lower. Evernote's web-clipping and PDF annotation features remain strong, and OneNote's freeform canvas is unique. But from a pure performance standpoint, both belong in Tier 3. If you are on an 8 GB Mac, these apps will consume resources that could be better used by your browser, email client, or development tools.
Battery Drain Comparison Table
The 6x range between the lightest and heaviest app is the single most important takeaway from this testing. The table below shows battery drain per hour for all eight apps during continuous editing on the MacBook Air M3.
| App | Tier | Battery Drain / Hour |
|---|---|---|
| Drafts | 1 (Native) | 2.1% |
| Bear | 1 (Native) | ~3.0% |
| Apple Notes | 1 (Native) | ~3.5% |
| Craft | 1 (Native) | ~4.0% |
| Reflect | 2 (Tuned) | ~5.0% |
| Logseq | 2 (Tuned) | ~5.5% |
| Obsidian | 2 (Tuned) | ~6.5% |
| OneNote | 3 (Heavy) | ~8.0% |
| Evernote | 3 (Heavy) | ~10.0% |
| Notion | 3 (Heavy) | 12.4% |
RAM Idle Comparison Table
Idle RAM matters because it determines how many apps you can keep open simultaneously. On an 8 GB Mac, every megabyte counts. The table below shows resident memory after five minutes of inactivity.
| App | Tier | Idle RAM |
|---|---|---|
| Bear | 1 (Native) | 84 MB |
| Drafts | 1 (Native) | ~90 MB |
| Apple Notes | 1 (Native) | 142 MB |
| Craft | 1 (Native) | ~180 MB |
| Reflect | 2 (Tuned) | ~280 MB |
| Notion | 3 (Heavy) | 312 MB |
| Logseq | 2 (Tuned) | ~350 MB |
| Evernote | 3 (Heavy) | ~350 MB |
| Obsidian | 2 (Tuned) | 478 MB |
| OneNote | 3 (Heavy) | ~280 MB |
To put these numbers in context: if you keep Bear, Apple Notes, and Safari open simultaneously, you use roughly 500 MB of RAM. If you keep Obsidian and Notion open instead, you use nearly 800 MB — before you open a single other app. On an 8 GB machine, that difference determines whether your system starts swapping to disk during routine multitasking.
Which Mac Model Are You Using? A Decision Tree
Your hardware budget determines which tier you can comfortably run. Here is a simple framework based on the testing results.
- 8 GB MacBook Air (M1, M2, M3): Stick to Tier 1 apps. Apple Notes, Bear, Drafts, or Craft will give you the fastest experience and the longest battery life. If you need Obsidian or Notion, open them as session-based tools — launch, work, quit. Do not leave them running in the background.
- 16 GB MacBook Pro (M1 Pro, M2 Pro, M3 Pro): You can safely use any tier. Tier 2 apps like Obsidian and Logseq will run comfortably. Tier 3 apps like Notion will still consume more resources than native apps, but the performance cost will be largely invisible during normal use.
- 18 GB+ MacBook Pro (M3 Pro, M4 Pro, M4 Max): Choose purely by workflow. The performance gap between native and Electron apps still exists, but your system has enough headroom to absorb it. If Notion is the best tool for your workflow, use it without worrying about battery or RAM.
Verdict: The Best Note-Taking App for Your Mac Depends on Your Hardware
The single most important factor in choosing a note-taking app for Apple Silicon Macs is not the feature list — it is the architecture. Native Universal 2 apps (Apple Notes, Bear, Drafts, Craft) launch faster, use less RAM, and drain less battery than their Electron counterparts. The difference is measurable and, on an 8 GB MacBook Air, it is decisive.
If you are on an 8 GB MacBook Air, your best options are Apple Notes (fastest launch, excellent sync), Bear (lightest RAM footprint), or Drafts (lowest battery drain). If you need the power of Obsidian or Notion, use them intentionally — open them when you need them, close them when you do not.
If you are on a 16 GB+ MacBook Pro, the performance gap narrows. You can choose by workflow and feature set without worrying about system impact. But even on powerful hardware, native apps will always feel snappier and run cooler.
