Simple Memo vs Day One
Which Should You Choose?
The core difference between Simple Memo and Day One is the purpose of recording. Day One is a beautiful journaling app for preserving life moments with timestamps, locations, and photos. Simple Memo is purpose-built for instant capture: open in 0.4 seconds, type, and send to email.
Analyzing feedback from users who switched from Day One, I found that while Day One has high satisfaction as a journal, Simple Memo better fits the everyday need of quickly jotting down brief notes.
What is Day One?
Day One is an Apple Design Award-winning journaling app. It automatically attaches timestamps, locations, weather, photos, and videos to entries, creating a timeline of your life. The free plan allows 1 journal; Premium costs $49.99/year for unlimited journals, media, and end-to-end encryption. Available on iOS, Mac, Android, and Web.
Journaling vs Instant Capture: Different Workflows
When you open Day One, you see a beautifully designed timeline of past journal entries. Photo entries display auto-generated maps from EXIF data showing where the photo was taken, along with weather icons for that day. The "On This Day" feature lets you reflect on what you wrote one or three years ago -- it is truly designed as a "digital life record book." However, this rich feature set adds steps before you can create a new entry. You navigate through journal selection, new entry creation, and optionally template selection, which does not suit the need to "record a thought within 10 seconds."
On security, Day One's end-to-end encryption is exclusive to the Premium plan ($49.99/year). The free plan stores journal data without encryption, which is a concern for an app handling personal diary content. Additionally, Day One was acquired by Automattic (the parent company of WordPress.com), and some users are wary of potential changes to data handling policies. Simple Memo encrypts the on-device Outbox and send history with AES-GCM-256 (on the free plan too), and does not persistently store memo bodies on its servers — though it is not end-to-end encrypted.
An effective practical workflow is to use Day One for "evening reflection" and Simple Memo for "daytime capture." Throughout the day, quickly email thoughts and events via Simple Memo. In the evening, review your email inbox and compile the meaningful items into Day One as a journal entry. This approach gives you both the speed of instant capture and the depth of reflective journaling.

4 Differences Between Journaling and Memos
- 1Purpose of Recording: Reflection vs Transfer
Day One records for "looking back" — the value is in reading what you wrote a year ago today via its timeline. Simple Memo "transfers present thoughts to your future self." Delivered as email, each memo connects directly to your next action. - 2Metadata: Location & Weather vs Text-Only
Day One auto-generates maps from photo EXIF data and attaches weather icons. Simple Memo focuses solely on text with no extra metadata. For short idea memos that need no context, Simple Memo's lightness is an advantage. - 3Privacy Model: No iCloud vs Automattic-Managed
Day One was acquired by Automattic (parent of WordPress.com), raising data handling concerns. The free plan has no E2E encryption. Simple Memo does not use iCloud and provides AES-GCM encryption even on its free plan. - 4Pricing Comparison: $49.99/yr vs $5/mo
Day One Premium costs $49.99/year for E2E encryption and unlimited media. Simple Memo is free for 3 sends/day, with Premium at $5/month for unlimited sends. If recording memos is your only goal, Simple Memo offers better value.
The Boundary Between Journaling and Memo-Taking
Many people install Day One with the intention of journaling regularly, but few actually maintain the habit. The reason is that journaling requires cognitively demanding reflection and emotional processing. In contrast, Simple Memo's act of instantly sending a thought carries virtually zero cognitive load. Understanding this distinction reveals the optimal way to use Day One and Simple Memo together. Journaling belongs to quiet evening hours; memos exist to capture daytime thoughts before they vanish.
A practical workflow: during the day, use Simple Memo to send fragmentary thoughts to email. In the evening, review those emails and write a day summary in Day One. This way, your Day One entries become high-quality records based on raw material captured throughout the day. Without Simple Memo, most daytime ideas are forgotten by evening, making journal entries thinner. The two tools are not competitors but complementary layers that capture thinking at different depths.
Psychologically, the act of writing has two modes: "externalization" (getting thoughts out of your head) and "introspection" (examining your inner world). Simple Memo is optimized for externalization, while Day One is designed for introspection. Trying to force one app to handle both inevitably compromises each function. The inconvenience of taking quick memos in a journaling app, and the inadequacy of journaling in a memo app, both stem from this fundamental mismatch.

FAQ
What is the difference between a journal and a memo?
A journal records the past for reflection — preserving moments with dates, locations, and emotions to read years later. A memo transfers present thoughts to your future self for action. Day One excels at the former, Simple Memo at the latter. If you need both, use them together.
Is Day One's E2E encryption available for free?
No. Day One's E2E encryption is exclusive to the Premium plan ($49.99/year). The free plan stores journal data without encryption. Simple Memo provides AES-GCM encryption on its free plan, keeping your private memos encrypted on-device.
Should I switch from Day One to Simple Memo?
Rather than switching, we recommend adding Simple Memo alongside Day One. Continue Day One as your journal and add Simple Memo for quick daytime capture. The workflow of sending via Simple Memo then compiling into Day One each evening leverages both tools' strengths.
Does Simple Memo have Day One's "On This Day" feature?
No, Simple Memo has no retrospective features. It is fully specialized for sending thoughts to email instantly. Use Day One for beautifully reflecting on the past, and Simple Memo for capturing thoughts at maximum speed.
Is Day One data safe after the Automattic acquisition?
Automattic (parent of WordPress.com) acquired Day One in 2021. No major policy changes have occurred, but some users are concerned about private diary data handling. Simple Memo never stores memos on a server — it sends directly to your existing email provider.
