Description

From the listing uploaded by “appupdater”.

This app listens when you pour hot water into a cup and analyzes the pouring noise to estimate the water temperature. The accuracy reaches ±4 degrees when tested under optimal conditions but is generally lower. The accuracy is higher at high temperatures and it can be useful for e.g. brewing different teas at their correct temperatures but it is not intended to be used for temperatures less than 50°C (122°F). The app visualizes a probability distribution and gives an 80% confidence interval for the temperature that depends on the vessel, pouring technique, and background noise. The probability distribution has been verified on a wide range of setups, but still assumes a prior distribution of pouring setups. How does it work? The properties of water and air vary with temperature. This results in changes in how noise is generated from pouring water. This app uses a pre-trained machine learning model to analyze pouring noises to get an estimate of the temperature. The longer time you pour, the more noise it receives, and it can give better estimates.

AI Thermometer APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the AI Thermometer APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 05553f3cafa1a13dc99754714bd85cfc.
