iCelsius by Aginova
The current app downloaded from the App store will read the temperature, create graphs and set up alerts. The iCelsius measures temperatures between -22°F to 158°F (-30°C to 70°C) and is suited for many applications.
A stainless steel tip makes it possible to measure liquid temperatures such as baby formula, cooking ingredients, wine, tea, household appliances and hundreds of other applications. Can also be used in school or for teaching science.
