Frequently Asked Questions

It’s a private tracker for restless legs syndrome. You log symptoms, meals, supplements, medications, and sleep — and the app surfaces patterns, triggers, and a personalized “tonight’s forecast” built from patterns in your own history. The forecast is an observation of your data, not a clinical recommendation.

The first 7–10 days mostly fill the baseline. After about two weeks of regular logging, the contribution heatmap and trend charts get meaningful. Forecasts get sharper as your dataset grows.

No. The more consistent you are, the better the patterns — but the app handles gaps gracefully. Quick Log on the Today tab is designed for one-tap entries when you’re in a hurry.

On your iPhone, and (if you have iCloud enabled) in your private CloudKit database for syncing across your devices. Nothing goes to our servers — we don’t run any. See the Privacy Policy.

We don’t. RLS Log contains no analytics SDKs, no marketing trackers, and no custom telemetry from us. We don’t see what you log, what screens you open, or even when you launch the app.

To be precise: because the app uses Apple’s iCloud and CloudKit to sync your data across your own devices, Apple’s platform-level operational logging applies — the same logging that runs for every iCloud-enabled app on your iPhone. Apple is the only party with any visibility there, and the contents of your CloudKit private database are end-to-end-managed and not visible to us. We never receive a copy.

Yes. Settings → Data → Export gives you a JSON file with everything you’ve logged. Save it to Files, share it, or keep it as a backup.

Deleting the app from your iPhone removes the local copy. To remove the iCloud copy, go to Settings → [Your name] → iCloud → Manage Account Storage → RLS Log → Delete Data.

Only what’s relevant to RLS: sleep analysis, workouts, active energy, step count, resting heart rate, and (optionally) clinical lab records like ferritin and vitamin D. Each category is a separate permission you grant in Settings.

Clinical records are lab results, medications, immunizations, and conditions that Apple Health imports from your healthcare provider. RLS Log can read lab results only, and only if you opt in — it’s used to auto-populate the lab targets you’ve set with your doctor so you don’t have to type values manually.

Yes. Settings → Privacy & Security → Health → RLS Log lets you toggle each category individually or revoke access entirely.

Only when you log a caffeine or alcohol entry yourself with a specific time. RLS Log writes that single sample (the milligrams of caffeine, or the number of standard alcoholic drinks) back to Apple Health so other Health-aware apps see the same entry. The app does not write sleep, activity, workouts, water, calories, iron, audio exposure, or menstrual data, and it does not write to Apple Health Records (clinical lab results) — those categories are read-only.

If you’d rather not have RLS Log write at all, you can revoke the write permission per-category in Settings → Privacy & Security → Health → RLS Log. Logging caffeine and alcohol in the app keeps working either way.

Goals are targets you set for yourself — for example, a ferritin level you and your doctor have agreed on, or “walk 30 minutes a day.” The app tracks progress and can remind you to retest a lab on a schedule.

Iron deficiency is one of the most common physiological contributors to restless legs symptoms. Many practitioners aim for ferritin above 75–100 ng/mL in people with RLS. The app makes it easy to track that target alongside your symptom log. (This is informational, not medical advice — talk to your doctor about what’s right for you.)

Yes. Open the Goals tab → tap a lab → Add Result. You can enter the value, the date drawn, the lab name, and any notes.

The app combines your recent triggers (caffeine, alcohol, late meals, missed medications, poor sleep), your symptom history for the time of day and day of week, and any goals or lab values you’ve flagged as relevant. It produces a score with headwinds (what’s working against you tonight) and tailwinds (what’s working in your favor) so you can see why — not just the number.

The forecast is a pattern-matching observation of your own logs, not a clinical risk assessment or medical advice. Tap the forecast card to expand it — the headwinds/tailwinds breakdown carries that same framing in the form of a short disclaimer right below the factor list.

The app needs roughly 14 days of data before predictions are stable. Until then, the Insights banner notes that the model is still warming up. The “not medical advice” disclaimer in the expanded forecast view applies during the warm-up period as well — the framing of the forecast does not change once the model has enough data.

A grid that highlights which logged items most strongly correlate with your worst symptom days. It’s not a medical diagnosis — it’s a visualization of your own patterns.

The predictions and pattern detection run entirely on your iPhone, against your own log history. There are no remote AI calls, no cloud inference, and no training pipeline that ingests your data.

Yes. Settings → Reminders lets you schedule daily prompts at custom times.

Yes. When you set a Goal, you can attach a follow-up date and the app will schedule a local notification.

Yes. Say “Hey Siri, log RLS symptom in RLS Log” — the app name has to be in the phrase or Siri won’t know which app you mean. Other built-in phrases include “log my mood in RLS Log,” “log water in RLS Log,” and “log caffeine in RLS Log.” You can also build custom Shortcuts that log specific triggers, start Live Activities, or open the Today tab.

Yes. Start a session from the Today tab and the Live Activity surfaces on the Lock Screen and in the Dynamic Island, with one-tap buttons to log severity and end the session.

RLS Log can optionally connect to your own self-hosted Home Assistant server to read sensor states — for example, bedroom temperature, humidity, or motion-sensor activity overnight — and correlate them with your sleep and symptoms. It is off by default and the app is fully usable without ever turning it on; you only need to touch this if you already run Home Assistant on your own network and want that context inside RLS Log.

If you enable it, you provide your own Home Assistant URL and a long-lived access token. Your iPhone makes HTTPS requests directly to your Home Assistant server over your local network or VPN. RLS Log is strictly read-only with respect to Home Assistant — it never writes, never modifies your server, and never sends any of your symptom logs, meals, supplements, medications, lab results, or other RLS Log data to Home Assistant or anywhere else. The URL and token you configure stay on your device.

The toggle lives in Settings → Integrations → Home Assistant. There is no demo server — by design, this is a connection to infrastructure you already own.
