Driftor: Know When You're Ready to Focus

Driftor reads your sleep, timing, and recovery signals from Apple Health and gives you a research-informed estimate of whether now may be a good window for deep work. It also tracks focus sessions and learns your personal patterns over time. Everything stays on your device.

It says when it is still learning
Driftor does not manufacture confidence from thin data. During calibration, it explains that it is learning from your sleep, timing, recovery signals, and focus history. You can ask for a notification when a stronger window appears or log work anyway so the app has more context.
Highlights
- Clear learning state while your personal baseline develops
- Updated timestamp shows when signals were last evaluated
- Optional notification when Driftor finds a stronger window
- Log work in any state without treating it as an error


Know when a deep-work window may be open
When your recent signals line up, Driftor shows a Primed state with an estimated focus window and a plain-language reason. The call is based on your recent sleep, timing, and recovery context rather than a generic population score.
Highlights
- A calm readiness ring communicates the state at a glance
- Estimated window helps you choose a practical focus block
- Plain-language reasoning accompanies every call
- Start a focus session directly from the readiness screen
A ‘not now’ state does not block your work
Sometimes the available signals do not support a strong focus window yet. Driftor says so plainly, can remind you to check again, and still lets you log work. Those lower-readiness sessions are useful because your own quality rating helps reveal whether the estimate fits your real experience.
Highlights
- No false precision when the current window is unclear
- Daytime nudges can prompt a later recalculation
- Work can be logged regardless of the current state
- Your feedback helps personalize future reports


Recovery is presented as guidance, not a diagnosis
A Recovery state means recent signals suggest that rest may be the better move right now. Driftor keeps the language measured, allows you to work if you choose, and makes clear that the result is wellness guidance rather than medical advice or a real-time HRV reading.
Highlights
- Sleep carries the strongest weight in the readiness context
- HRV and resting heart rate are compared with your baseline
- Circadian timing and hours since waking add context
- Health signals are processed locally on your device
Track focused work while it is happening
Choose a 25, 50, or 90-minute block and keep working while Driftor tracks the session. A Live Activity keeps progress visible from the Lock Screen and Dynamic Island, and you can add time or finish early without losing the session context.
Highlights
- Targeted 25, 50, and 90-minute focus blocks
- Live Activity on the Lock Screen and Dynamic Island
- Add time or finish a block when the work changes
- Readiness context stays attached to the session


Turn completed sessions into a private pattern
Weekly reports compare completed sessions, readiness context, and your quality ratings. As the history grows, Driftor can surface clearer personal windows and quality trends. Focus history syncs through your private iCloud so it can continue across your own devices; Health data remains on-device.
Highlights
- Weekly summary of completed focus sessions
- Best-window and quality-trend observations
- Reports improve as sessions and ratings accumulate
- Private CloudKit sync without a Driftor account

Questions
Frequently asked questions
How does Driftor know when I am ready to focus?
Driftor reads Apple Health signals that research links to recovery and cognitive readiness — sleep, circadian timing and hours since waking, resting heart rate, and heart-rate variability — and compares them with your personal baseline. It is a research-informed estimate, not a medical or real-time reading.
Do I need an Apple Watch?
No. Driftor works with health data available from your iPhone. An Apple Watch can add richer recovery signals, especially HRV and heart-rate data, which may provide more context, but it is not required.
Is my health data uploaded anywhere?
No. Health data is processed on your device and is not sent to 3Nsofts or a third-party server. Focus session history can sync through the private CloudKit database associated with your iCloud account.
Why does Driftor say it is still learning?
Driftor needs enough personal history to establish useful baselines. When data is limited, it shows a learning state instead of presenting a confident call that the available information cannot support.
Can I track work when it says not now?
Yes. You can log a focus session in any state. Sessions completed during lower-readiness periods provide useful context when you later rate their quality.
Is Driftor a medical device?
No. Driftor provides wellness and productivity guidance only. It does not diagnose, treat, cure, prevent, or monitor any disease or medical condition.
What does Pro include?
Pro unlocks upcoming-window estimates, full focus history and pattern reports, and optional notifications when Driftor identifies a Primed state. The free version includes the current readiness read and focus tracking.
