The whole fever, on one screen.
Live readings every 5 seconds, the full temperature curve, custom alerts and family sharing — the app is where P20's data becomes decisions.
Live fever curve
Every 5-second reading plotted in real time. See the trend — rising, plateauing, breaking — not just the current number.
Custom alert thresholds
Choose the temperature that matters for this child or patient. The app stays silent until it's crossed, then alerts loudly.
Family sharing
Multiple phones can watch one sensor. A parent at work, grandparents in another city — everyone sees the same live data.
Exportable history
Complete temperature records, exportable for doctor visits or telehealth consultations.
Kick-blanket alerts
The app flags the sudden temperature drop pattern of a kicked-off blanket, so you can act before the child gets chilled.
Automatic pairing
The sensor pairs on first launch. First-time setup takes about two minutes; after that, it just connects.
Set up the temperature monitoring app in two minutes
Pair
Open the app; the P20 sensor connects automatically.
Set the alert
Pick the threshold temperature for this patient.
Watch — or don't
The curve builds itself. You'll be alerted the moment it matters.
What a temperature monitoring app has to get right
Why a fever tracking app is more than a number on a screen
Most thermometer apps exist to display whatever a Bluetooth thermometer just measured — a single value, refreshed on demand. The P20 app is built around a continuous stream instead: a reading every 5 seconds, rendered as a live curve so the shape of a fever is visible at a glance, not just its current value. That distinction is what separates a fever tracking app from a simple Bluetooth display.
How the remote temperature monitoring app handles alerts
Every user sets their own threshold — there is no universal "normal," and a paediatrician's guidance for a child differs from a facility's protocol for an elderly resident. The app stays silent below that number and pushes an immediate notification the instant it's crossed, with escalating alerts if temperature keeps climbing. This is the core mechanic that lets caregivers stop checking manually altogether.
Thermometer app with alerts: family sharing in practice
A single sensor can be watched by more than one phone at once. A parent at work, a co-parent, or a grandparent helping with care all see the same live readings and receive the same alerts — there's no primary and secondary viewer, just shared visibility into one data stream. This matters most exactly when the person watching isn't in the same room as the person wearing the sensor.
Data you can actually use afterward
Every session is retained as an exportable history, not just the live view. That means a full night's fever curve, or several nights of basal body temperature readings, can be pulled up and shown to a doctor rather than recalled from memory. For anyone integrating against the platform, the same data is available programmatically — see our SDK and system integration page.
Temperature monitoring app questions
Does the temperature monitoring app work on both iPhone and Android?
Yes, the companion app supports both iOS and Android, connecting to the P20 sensor over Bluetooth Low Energy with automatic pairing on first launch.
How do I set up a fever alert in the app?
Open the app, let the sensor pair automatically, then choose your threshold temperature. The app stays silent until that exact value is crossed, then sends a push notification and can sound an audible alert.
Can more than one person receive alerts from the same sensor?
Yes. Family sharing lets multiple phones follow the same sensor's live readings and receive the same threshold alerts simultaneously, which is useful for co-parents, working parents, or remote family members.
Does the app detect a child kicking off their blanket?
Yes — kick-blanket detection recognises the characteristic drop-then-rebound temperature pattern and alerts the caregiver, rather than mistaking it for a fever resolving on its own.
Can I export my temperature history to show a doctor?
Yes, the app retains a full history of readings that can be exported for a doctor's visit or a telehealth consultation, showing the complete curve rather than a remembered summary.
Does the app work for basal body temperature tracking as well as fever monitoring?
Yes — the same app supports both modes. Fever monitoring uses ±0.2°C accuracy and threshold alerts, while BBT tracking uses the sensor's 0.01°C resolution and continuous overnight sampling.
