The heat it® for iPhone has a Lightning connector and is compatible from the iPhone 6s up to the latest model (iPhone 14). The Apple MFi certification ensures best functionality and highest security.
Compatibility with Tablets / iPads
The heat it® app was developed especially for smartphones and is not optimised for tablets. In addition, it is much easier and handier to use with a smartphone.
The Android heat it® cannot be used with Apple iPads with USB-C connection.
Frequently Asked Questions
When do I use the heat it®?
For best results, apply the heat it® immediately after the insect bite. If you apply it immediately, you can often prevent the symptoms altogether, but if you apply it later, the symptoms can subside more quickly.
How hot does the heat it® get?
The heating plate of the heat it® heats up to 48 °C to a maximum of 53 °C, depending on the setting. In the "Adult" setting, the heating plate heats up to a maximum of 53 °C. In the "child" setting, the heating plate heats up to a maximum of 50°C. If you activate "sensitive skin area", the temperature is reduced by about 2°C.
Is the treatment painful?
Whether the application is perceived as painful depends on the user. It may happen that the treatment is perceived as unpleasant. We recommend always start with a short treatment at a low temperature ("Short", "Child" & "Sensitive skin area"). The settings can then be adjusted as needed. As the temperature sensitivity of the skin varies depending on the person and the part of the body, the heat it® offers different settings for an optimised treatment. For safe and effective use, please note the following:
Only a slight heat pain is required for successful treatment. In case of severe pain, stop the treatment immediately. For first-time use, we recommend using the settings "short", "child" and "sensitive skin area". The same applies to the treatment of areas of the body that have not yet been tested. If the treatment is not successful, the treatment can be repeated after a waiting time of 2 minutes with adjusted settings. Please observe the detailed information in the instructions for use.
What should I pay attention to?
heat it® may be used on children from the age of 4. From the age of 12, heat it® can be used independently.
heat it® must not be pressed onto the skin during the heating process and not for longer than 10 seconds. The same skin area must not be treated more than five times per hour. There must be a break of at least 2 minutes between repeated treatment of the same skin area. Excessive use may cause skin lesions or persistent discolouration of the skin (caloric hyperpigmentation).
heat it® is designed for use on external skin only. Do not use the appliance in body orifices, on mucous membranes, on the gums, nail bed, eyes or external auditory canal.
When using for the first time, the setting "short", "child" and "sensitive skin area" must be selected. The same applies to the treatment of body parts that have not yet been tested.
When treating a bee sting, the bee stinger must be removed beforehand. heat it® is not suitable for treating allergic reactions or tick bites.
A longer treatment duration ("medium" and "long") and higher temperature ("adult" and "non-sensitive skin area") can cause skin irritation in sensitive persons and on sensitive skin areas (e.g. inside of the arm, Achilles heel)! Do not use these settings if you are unsure or if you are using them for the first time. It is imperative to follow the instructions for use. Improper use can lead to minor burns.
How does the principle of action work?
The principle of hyperthermia for the treatment of itching and pain works by briefly heating the skin, to which the nerves react. According to the current state of research, it is assumed that this reduces the transmission of the stimulus. Thus, the itch signal can no longer be transmitted properly and the need to scratch disappears. To achieve this itch-relieving effect on skin nerves, a brief heat pain is necessary.
How much battery does heat it® consume?
Up to 1,000 treatments are possible with a fully charged smartphone. That's enough for you, your family and all of your friends.
