Handy for my purpose of seeing the centigrade temperatures on the Fahrenheit scale with which I am much more familiar with. Getting annoyed by the ads that come up first, filling the entire page, hiding the temperature conversion app. Will uninstall. Lay out is otherwise clean, quick and easy to read. Had it at 5 stars and downgrading to 3 stars.
A useful app. It helps when dealing with Americans from the UK as they are in Fahrenheit and we are in Celsius. Also, the elderly in the UK may still think in Fahrenheit and not understand what the Celsius number is, in real terms. Thank you to the Devs for an easy-to-use app ! Another year on - 2026 - still a very useful app. Thank you for making it easy to use and easy to swop between the 2. 🙂
app blocked from view by ads that cover entire app. has become useless.
We have an indoor/outdoor thermometer and it keeps reverting to Celsius. It is a lot easier to use this app than to fight with the thermometer to change to Fahrenheit. This app is easy to use and has been a great teaching tool as well. I am getting better at reading Celsius and quizz myself before verifying with the app.
Clunky. The input keys are organized in a nonsensical way - not like a phone keyboard nor like a calculator or regular keyboard. Sometimes the app also takes multiple seconds to launch. It's quicker just to type "20 c in f" into the Google search bar at that point.
This software is riddled with bandwidth intensive video advertising EVERY TIME the app starts! If you want better reviews then learn to use less intrusive advertisements that do not inconvenience the user. This is basically glorified adware with the added functionality of a metric converter xD For those of you considering downloading this pretentious garbage- please don't waste your time. Find another app for your unit conversations. As for the developer: Your app means nothing. Justify that.
easy to use and informative
Great little app and perfect for I need. So simple to use...only thing is it keeps on asking for me to rate it. since this post it has asked 5 times. Guess it's a glitch. other wise I love it...it's a minor inconvenience.... but had to edit my reply and I guess I'll drop it from 5 to 4.
Quick - simple - easy. Love it as a practical and FREE app, but have not yet seen option to purchase it and remove ads. Ads are not as much a nuisance, though, as with other apps.
Just what I wanted. Simple converter. Works Great! Still using! Just reloaded the App. Phone crashed and I forgot some of the apps I had and this was one of them. Simple, precise, easy to use.
I love this app. The entire world uses metric save two countries. The United States is one of those two countries. Metric is the more accurate system. I've lived in Europe for some time so, I've gotten used to metric measures. Except for Celsius. Which is why this app is so easy and helpful.
The ads are really pitiful. Opening this app up and the editor from Google for the code this thing is written in launches. There then follow more ads instead of the simple calculator desired. Loose the adds, and back to what your software core competency is.

A simple app which does what I need. Converting metric temperature readings to fahrenheit. It is logically laid out with large, bright, & colourful characters which make it easy to use day or night.
Does exactly what it says! Yes there's ads but it's a free app so it's to be expected. Only 1 ad pops up in the beginning so not bad at all. Happy user, thank you!
We are stationed in Korea for two years. This app has been a lifesaver when it comes to cooking with mybKorean stove and knowing the correct temperature for my recipes from farenheit to Celsius. It also helps me to know what temperature to set my air conditioning and heated floors to.
I like this app. The world doesn't calculate on the same numbers line as I do. Celcius has its place but not in a world of a pinch of this, a handful of that - when exactitudes are not necessary. Thank you for this free app!
Too many ads that don't have an easy way to close, and some you can't even find a way to close them. Wish I could just purchase this once and do away with ads, but they don't have that option either.
I watch France24 for my news of the world. They give temperatures from the various countries in Celsius. I find this tool invaluable, as I was finding myself increasingly distracted by trying to do the math in my head.
Free version plays video ads with sound, so lots of situations where it won't be appropriate to open the app.
