## What is Thermometer Log?

This app is an app that allows you to easily record your body temperature. You can record many times a day!
In addition, two units of body temperature can be used: Celsius (℃) and Fahrenheit (℉).

Just move the scale on the home screen left and right to set the body temperature, and tap the save button to easily record the body temperature and save time! Since it can be recorded many times a day, it is ideal for recording body temperature in the morning and at night.

On the "Analysis" screen, a graph of weekly, monthly, and 3-month body temperature is displayed. In addition, the average body temperature for that period is displayed. You can check the data by tapping the graph.

On the "History" screen, the record of the body temperature of the year and month selected in the upper right of the screen is displayed. You can correct the body temperature data by double tapping the data. If you forget to record the body temperature data, you can add it by tapping the "Add" button on the upper left of the screen. When you tap the "Add" button, the input screen will be displayed. Select and add the date, time, and body temperature. By tapping the "Export CSV file" button, you can convert the history data to a CSV file and attach it to an email for export.

On the "Settings" screen, you can set the unit of body temperature. You can also set the day of the week at the beginning of the week in the weekly graph. You can choose to start on Monday or Sunday.

In the free version, you can check the body temperature record for up to one week.
If you have an unlimited recording period and want to check monthly or 3 month data, please consider purchasing the premium version in the app.

**Developer response:** Obrigado por baixar o aplicativo de registro de temperatura corporal.
Este aplicativo é para registrar a temperatura corporal medida pelo termômetro, por isso, sinto muito, mas este aplicativo em si não pode medir a temperatura corporal.
Lamento que a explicação do aplicativo seja insuficiente.
Se você tiver algum recurso que gostaria que adicionássemos, agradeceríamos se você pudesse nos informar novamente.

This app is for recording the body temperature measured by the thermometer, so I'm very sorry, but this app itself cannot measure the body temperature.
I'm sorry that the explanation of the app is insufficient.
If you have any features you would like us to add, we would appreciate it if you could let us know again.
