Comparison
Memtime gets the important thing right - automatic capture, stored locally. People leave over the subscription, the billing-first design, or wanting a readable record instead of minute grids. The alternatives, honestly compared.
Memtime records which programs you use in minute increments, keeps that data offline on your device, and helps you convert it into time entries for tools like Jira and ClickUp. It is honest software with a clear audience: people who bill. The usual reasons to want an alternative: price (from roughly €10/month on the 2-year commitment, more on shorter terms), the workflow (everything funnels toward time entries and project sync you may not need), and the output (minute-by-minute program grids rather than an account of what you actually did).
Dayflow keeps Memtime's local-first principle and removes the price and the busywork: fully automatic, AI writes your day into readable sentences, 100% local, and free - the only Mac tracker with all four at once.
| App | Price | Automatic | AI summaries | Data stays local | Open source | Billing features |
|---|---|---|---|---|---|---|
| Dayflow | $0 (Pro optional, $16/mo annual) | Yes | Yes | Yes | Yes (MIT) | No |
| Memtime | From ~€10/mo (2-year rate) | Yes | No | Yes | No | Yes |
| Timing | From ~$10/mo | Yes | No | Cloud sync | No | Yes |
| Qbserve | One-time purchase | Yes | No | Yes | No | Basic |
| ActivityWatch | $0 | Yes | No | Yes | Yes | No |
Dayflow records your screen at one frame every 10 seconds and has AI summarize what you were actually doing - not which programs were open, but what happened in them. Recordings and the timeline stay on your Mac (fully offline with a local model via Ollama or LM Studio); the app runs on ~100MB of RAM and under 1% CPU. Honest cons: Mac-only, and deliberately no invoicing, rates, or project-tool sync - if Memtime's billing pipeline is why you use it, keep Memtime.
Timing is the Mac-native power tool for billable time: automatic capture of apps, documents, and sites, assembled into projects with per-project rates and the deepest reporting in the category. Sync runs through Timing's cloud on current plans - the main trade against Memtime's offline stance.
Qbserve tracks Mac activity locally with productivity scoring and basic invoicing, for a single payment. Development is slow these days, but the no-subscription deal still stands alone.
ActivityWatch is the open-source classic: apps, window titles, and browser activity logged locally on Mac, Windows, and Linux. Raw buckets and utilitarian charts, no AI and no billing - and if you want a readable layer on top, that is Dayflow's whole pitch.
If you bill clients and Memtime's sync saves you real invoicing time, it is worth its subscription - Timing is the main rival for that job. If you came to Memtime for private, automatic capture of your day and the billing machinery is dead weight, Dayflow does the capture better (a readable AI journal instead of minute grids), keeps everything just as local, and costs nothing.
Dayflow, if what you want is Memtime's automatic, local capture without the subscription: it records your screen, writes an AI timeline of your day, stores everything on your Mac, and costs $0 (open source, MIT). ActivityWatch is the free cross-platform pick for raw activity data.
Yes - this is Dayflow's main difference. Memtime shows your captured activity as minute-by-minute program usage that you turn into time entries. Dayflow has AI write the day into readable sentences ("Implementing OAuth token refresh, 9:04-9:48"), so the record is useful without any assembly work.
Billing workflows. Memtime syncs finished time entries into project software like Jira, ClickUp, and asana, supports billable rates, and covers Windows and Linux. If you reconstruct billable hours for clients, Memtime or Timing remains the better tool.
Yes - both store captured activity on your device rather than a vendor cloud, which sets them apart from Timely, Rize, and RescueTime. The difference: Dayflow is open source, so the local-only claim is auditable in public code; Memtime is closed source.
Dayflow is $0, open source, and everything stays on your Mac.
