How can we help?

Your kit includes the Stemp patch, a charging base, and a quick-start card. To begin:

1. 1Charge the patch fully on the base (about 90 minutes).
2. 2Download the Stemp app and create an account.
3. 3Apply the patch to your upper arm or chest and pair it in the app.

Place the patch on clean, dry skin on the upper arm or upper chest, away from bone and heavy hair. Press firmly for 10 seconds so the adhesive seals. Avoid lotion or oil on the area first, as it weakens the seal and can affect contact temperature.

The Stemp app is free on the Apple App Store and Google Play. Search "Stemp" or use the download links in your welcome email. One account works across all your devices and patches.

Each patch is rated for up to 14 days of continuous wear on a single charge. The app shows remaining battery and reminds you before it's time to swap in a fresh patch.

Yes. The patch is water-resistant and keeps reading through showers, sweat, and swimming. There's no need to remove it, just pat the area dry afterward so the adhesive stays put.

No. Your readings live in your Stemp account, not on the patch itself. When you activate a fresh patch, your trends and history continue without a gap.

Rest the patch on the charging base with the sensor side down. A full charge takes about 90 minutes; the base light turns solid when it's ready. You only recharge between wears, not daily.

Pairing takes about 15 seconds and is only needed once per patch:

1. 1Open the app and tap Add device.
2. 2Make sure Bluetooth is on and hold your phone near the patch.
3. 3Follow the on-screen prompt until you see live readings.

Most drop-outs are a Bluetooth hiccup. Try this in order:

1. 1Keep your phone within about 20 feet of the patch.
2. 2Confirm the app has Bluetooth permission enabled.
3. 3In the app, open Devices and tap Reconnect.
4. 4Still stuck? Gently re-seat the patch on your skin.

If readings don't return after that, contact us below and we'll help.

In the app, open Alerts and set your own high and low thresholds. When a reading crosses the line, you get a push notification instantly, and so does anyone you've shared with. You can set different thresholds for each person on your account.

Yes. The Trends tab charts every reading over hours, days, and weeks. Tap Export to generate a clean PDF summary you can email to a clinician or bring to an appointment.

Open Sharing in the app and send an invite by email. Once they accept, they get permission-based access to live readings and alerts. You choose what each person can see, and you can adjust or revoke access at any time.

Only people you explicitly invite. Your temperature data is encrypted end to end and never shared or sold. You can revoke a person's access, or delete your data entirely, whenever you like.

In Sharing, tap the person's name and choose Remove access. It takes effect immediately, and they'll no longer see readings or receive alerts.
