Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Day One

  • It moved from a one-time purchase to a subscription after the Automattic acquisition, so long-term cost is materially higher than the original pricing implied.
  • The free tier caps at one journal and 25 photo entries, which is restrictive enough that anyone journalling seriously for more than a few weeks needs to pay.
  • End-to-end encryption is opt-in per journal rather than on by default, so users have to actively choose it and understand which journals are protected.
  • Cancelling Premium after using multiple journals or heavy photo storage can leave content viewable but with sync and some features disabled, so people should export before cancelling.
  • As an Automattic product, its roadmap sits behind a company whose primary focus is WordPress and Tumblr, not journalling specifically.

Memtime

  • No free tier. There is a 14 day trial and after that the cheapest route is €10 a user a month on a two-year commitment, or €15 quarterly.
  • The integrations most buyers arrive for are on Connect, not Basic, so the entry tier is a local tracker with no link to the project software you already run.
  • Desktop only. There is no mobile app, so work done away from the computer has to be entered by hand.
  • Local-only storage is the product's point and also its limit: there is no central view for a manager, and a lost or wiped machine takes its timeline with it.
  • Tracking is at five or six minute granularity rather than to the second, which is right for reconstructing a day and wrong for anyone billing in one-minute units.

Answered from the vendors’ own pages

Day One: Is Day One still a one-time purchase?

No. Since the 2021 Automattic acquisition it is sold as Day One Premium, a subscription. Older lifetime purchasers were grandfathered but new users pay a subscription.

Memtime: Does Memtime send my activity data to a server?

No. Activity is stored locally on the device that recorded it and never reaches a server, which is the basis of the product's "built for privacy" positioning and why no manager console exists.

Source
Day One: Is encryption on by default?

No, end-to-end encryption is an option users turn on per journal, not a default for all entries.

Memtime: What does Memtime cost?

Per user per month, falling with commitment: Basic is €15 quarterly, €12 annual or €10 on two years. Connect is €22, €18 or €15. Premium is €30, €25 or €20. Enterprise is custom from 50 seats. Every tier has a 14 day trial with no card required.

Source
Day One: Can I export my entries if I cancel?

Yes, PDF and native Day One export formats are available regardless of subscription status, though some sync and premium features stop working.

Memtime: Which plan includes the integrations?

Connect and above. Basic covers automatic tracking, timesheets, calendars and reporting, but the 100+ project software integrations and the sync with them start at Connect.

Source
Memtime: How does the automatic tracking work?

It records the program and document in your foreground window at five or six minute granularity and builds a timeline from that. There is no timer to start, so nothing is lost to forgetting.

Source
Memtime: Which platforms does it run on?

Windows, macOS and Linux desktops. There is no mobile application.

Memtime: Who makes Memtime?

Memtime GmbH, a German company founded in 2016.
