Where each one falls short

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

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.

Spark Mail

  • Several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • It is a client over accounts you still pay for elsewhere, so the total cost is Spark plus whatever Gmail, Outlook or Fastmail plan you already hold.
  • The free tier lacks AI Copilot and summaries, so the features it is best known for sit behind the paid plan.
  • Team features are basic next to dedicated shared-inbox tools like Front or Help Scout, so a support team scaling past a few agents will likely outgrow it.
  • Windows and Android versions have historically lagged the macOS and iOS apps in feature parity.

Answered from the vendors’ own pages

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
Spark Mail: Does Spark host my email?

No. It is a client that connects to Gmail, Outlook, iCloud or any IMAP account; you still need a mail host.

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
Spark Mail: Does Spark store my email credentials on its servers?

For some features, including cross-device snooze and send-later sync, yes. It is part of how those features stay consistent across devices.

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
Spark Mail: Is there a one-time purchase option?

No, Spark is subscription only for individuals and teams; the base client is free but AI and unlimited scheduling need Premium.

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.
