CVS Tracker helps parents and carers record Cyclical Vomiting Syndrome episodes with calm, organised logging, even in the middle of the night.
ONE TAP TO LOG
Tap Sick now and the time is recorded, starting an episode if one isn't running. Add more when you can: how severe, symptoms, sleep and notes. If you tap by mistake, Undo is right there.
SICK NOW FROM ANYWHERE
While an episode is running, the Lock Screen and Dynamic Island show when they were last sick and how many times so far, with a Sick now button that records the time without opening the app. You can also long-press the app icon, ask Siri, use Shortcuts or the Action button, or add a Control Center button. Names stay off the Lock Screen unless you switch them on.
ONE TIMELINE PER EPISODE
Everything logged in an episode appears in one timeline, with when they were last sick at the top. Tracking more than one person? The app asks who's sick and keeps an episode for each.
MEDICINES, AS YOU ENTER THEM
Medicines are recorded exactly as you type them, and ones you've recorded before can be entered again in a tap. Set an optional reminder at the interval you choose; it tells you what was given and when.
PATTERNS
Plain answers about what you've recorded: how often episodes happen, how long they last and when they start.
DOCTOR REPORT
A clear summary of one episode or a period, to share with your medical team. Share it as a PDF, or as a CSV for spreadsheets, with Premium.
EASY ON TIRED EYES
Light and dark appearances, with colours that dim and warm automatically at night.
FAMILY SHARING (Premium)
Each carer uses their own account. Whoever logs, both phones stay in step, and each entry shows who logged it. One Premium purchase covers your whole family and includes cloud backup.
PRIVATE BY DESIGN
Your records are stored on your iPhone and work offline; no account is needed unless you share or back up. App Lock can ask for Face ID or your passcode. No ads, no data selling, no unnecessary tracking.
CVS Tracker records what you enter. It doesn't give medical advice, diagnose, or suggest medicines or doses. Always follow your medical team's guidance.
The Lock Screen needs iOS 17 or later; the Control Center button needs iOS 18 or later.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Notifications when someone else logs. When another carer, or a log-only phone, records sick or ends an episode, your phone tells you: one notification per episode, updated as more is logged. You can switch it off in Settings.
- Both Lock Screens stay current. When another carer starts an episode, the Lock Screen card appears on your phone too, and its time and count update as they log. Sick now on the Lock Screen is saved straight away, even with the app closed. (iOS 17 or later; the card appearing by itself needs iOS 17.2.)
- Your phone catches up in the background when someone else logs, so the episode and any reminders are up to date when you look.
- Log-only phones (Premium). Give a child, grandparent or babysitter a phone that can only log: Sick now, how they feel from 0 to 10, and symptoms, with Undo. That phone needs no account; it connects with a one-time code from the Family tab, and each entry shows which phone logged it.
- How they feel, from 0 to 10, in How are they?, the timeline, the Doctor Report and the CSV.
- Add a past episode from History, with just when it started and ended.
- Each time sick shows the gap since the one before, and whether it was longer or shorter than the previous gap.
- Sore throat can now be recorded as a symptom.
- If someone joins your family with their own profile for the same person, the Family tab asks whether to combine them. Nothing is combined without asking.
- A double tap on the Lock Screen's Sick now records it once.
- Fixed a blank screen after tapping some notifications.
