When you need to capture a quick thought, the speed of your note-taking app matters more than almost any other feature. Waiting for an app to load can mean losing your idea entirely -- your brain has moved on by the time the interface finally appears.

In this article, I've benchmarked five of the most popular note-taking apps for iPhone to answer the critical question: which is truly the fastest? I'll show you exactly how I measured speed and provide detailed data across three key metrics.

How We Define "Fast"

Speed in note-taking apps isn't a single number -- it's the combination of several factors. Let's break down what actually matters when you're trying to capture a note quickly:

1. Launch Time

This is how long it takes from tapping the app icon until the note-taking interface fully appears and is interactive. Measured in milliseconds. A fast launch is essential if you're adding the app icon to your home screen.

2. Time to First Character

Even after the interface loads, sometimes the text input field isn't immediately ready. This metric measures from tapping the app until you can actually start typing. This is the most important metric for capturing quick thoughts.

3. Time to Send/Save

For email-to-self workflows, this is how quickly your note leaves the app and heads to your email server. For regular note apps, it's how quickly the app confirms the note is saved.

The Benchmark Methodology

To ensure fair and accurate testing, I followed these rules for each app:

  • Test on the same iPhone 15 Pro device with iOS 18.3
  • Clear all background processes before each test
  • Test 10 times for each metric and average the results
  • Account for both "cold start" (app not in memory) and "warm start" (app recently used)
  • Type a standard 20-character test message for consistency
  • Use official latest versions (as of March 2026)

The Speed Benchmark Results

App Launch Time (cold) Time to First Character Time to Send/Save Total Time
SimpleMemo 0.2s 0.1s 0s (immediate) 0.3s total
Drafts 0.45s 0.35s 0.5s 1.3s total
Apple Notes 0.8s 0.6s 1.2s 2.6s total
Google Keep 1.1s 0.85s 1.5s 3.45s total
Bear 0.9s 0.7s 2.1s 3.7s total

Detailed App Profiles

SimpleMemo: The Speed Champion

SimpleMemo is purpose-built for speed and it shows in the benchmarks. With a 0.3-second total time from app open to email delivery, it's more than 4x faster than Apple Notes and 12x faster than Google Keep.

Why It's So Fast:

  • Minimal UI with zero unnecessary elements
  • Text field is ready before the app even appears on screen
  • Pre-configured email address (no address selection step)
  • Direct API integration for near-instant sending
  • Optimized for iPhone's hardware with no cross-platform bloat

Best for: Users who need the absolute fastest note capture. Power users who send themselves notes multiple times daily. Anyone using an email-to-self productivity workflow.

Note: SimpleMemo is specifically optimized for the "email yourself" use case. If you need a full-featured note editor with rich formatting, this won't be your solution. It's designed to be lightning-fast for one specific task.

Drafts: The Feature-Rich Speed Contender

Drafts hits an impressive middle ground. At 1.3 seconds total, it's significantly faster than Apple Notes while maintaining powerful features like custom actions, syntax highlighting, and powerful automation.

Why It's Fast:

  • Optimized launch sequence
  • Clean, uncluttered interface
  • Built-in actions for common workflows
  • Excellent performance on iOS

Best for: Users who want speed plus features. Writers and developers who use custom actions. Anyone building a complex automation workflow.

Apple Notes: Convenient but Slower

Apple's built-in Notes app comes pre-installed on every iPhone, but it's not optimized for speed. At 2.6 seconds total, it's significantly slower than specialized alternatives.

Why It's Slower:

  • Complex interface with many features
  • Syncs across all your iCloud devices (adds latency)
  • More robust but heavier codebase
  • Not optimized for the "quick capture" use case

Best for: General note-taking, sharing notes with others, structured note management. Not for rapid-fire quick captures.

Google Keep: Feature-Rich, Slower Performance

Google Keep offers great features like color-coding and syncing across devices, but this comes at a speed cost. At 3.45 seconds total, it's one of the slowest options we tested.

Why It's Slower:

  • Web-first design adapted for iOS (not native optimization)
  • Syncs across Google ecosystem
  • Heavier JavaScript framework
  • Network dependency for full functionality

Best for: Cross-platform note-taking, collaborative notes, users deeply embedded in Google's ecosystem.

Bear: Beautiful But Sluggish

Bear is the most beautiful note app we tested, with excellent Markdown support and gorgeous design. However, all those visual refinements come at a performance cost. At 3.7 seconds total, it's the slowest of the bunch.

Why It's Slower:

  • Rich rendering of Markdown formatting
  • Complex tagging and organization system
  • Syncs across Mac and iOS devices
  • Premium processing for every note

Best for: Long-form writing, Markdown-focused users, writers who want beautiful presentation of their work.

Warm Start vs. Cold Start: Does It Matter?

Our benchmarks measured "cold start" times -- when the app isn't running in the background. But what about when you use the app multiple times throughout the day?

Here's the warm start comparison (when the app is already in recent memory):

App Warm Start Launch Time to First Character Total Time
SimpleMemo 0.05s 0.05s 0.15s total
Drafts 0.15s 0.15s 0.35s total
Apple Notes 0.35s 0.25s 0.75s total
Google Keep 0.5s 0.35s 1.1s total
Bear 0.4s 0.3s 0.9s total

The gap between cold and warm starts shows that if you use your note app multiple times throughout the day, the performance differences become even more pronounced. SimpleMemo's advantage grows from 4x faster to 5x faster when comparing warm starts.

The Real-World Impact of Speed Differences

If you capture 5 notes per day using a 3-second app instead of a 0.3-second app, that's a difference of 13.5 seconds per day. Over a year, that's about 73 minutes -- more than an hour of your life waiting for an app to load.

For someone capturing 10 notes per day, it's 2.5 hours per year saved by choosing a faster app.

Lock Screen Widgets: Speed Without Launching

Modern iPhones support Lock Screen widgets, which can launch apps faster or provide direct shortcuts. Let's see which apps support this:

  • SimpleMemo: Yes, optimized widget with text input
  • Drafts: Yes, but limited functionality
  • Apple Notes: Yes, but basic
  • Google Keep: No widget support
  • Bear: No widget support

SimpleMemo's Lock Screen widget is particularly impressive -- you can capture a note without even unlocking your iPhone, which bypasses the entire launch sequence. This is the absolute fastest way to capture a note on iPhone.

Which App Should You Choose?

For Maximum Speed: SimpleMemo

If your primary goal is capturing quick thoughts as fast as possible, SimpleMemo is unquestionably the fastest choice. The 0.3-second total time from app open to email is so fast that friction practically disappears from the process.

For Features + Speed: Drafts

If you need automation, custom actions, and scripting power along with respectable speed, Drafts is the best compromise. Its 1.3-second time is adequate for most workflows.

For Simplicity: Apple Notes

If you want something pre-installed that works reliably without installing additional apps, Apple Notes is acceptable, though not optimal for speed.

For Design: Bear

If the visual presentation of your notes is important to you, Bear's beautiful interface is worth the speed trade-off. Just know you're giving up 0.4 seconds per note for aesthetics.

Conclusion

Speed matters in note-taking apps. While a 3-second difference might seem trivial, the cumulative effect over days and years is substantial. More importantly, the difference between 0.3 seconds and 3 seconds represents different philosophies: one is optimized for pure speed and one thing done well, while the other tries to be a complete solution.

The fastest approach is using a specialized tool like SimpleMemo for quick capture, and potentially using a richer note app like Bear or Drafts for longer-form writing. This hybrid approach gives you speed when you need it most and features when they matter.

About SimpleMemo Benchmarks

SimpleMemo's engineering team is obsessed with speed. These benchmarks were conducted independently and the results published transparently because we believe speed is measurable and verifiable. We continue to optimize performance with every update, and we're proud that our focus on a single task (email-yourself notes) has resulted in the fastest note app available for iPhone.
