Ads keeping showing whilest part way through calculations and feedback on the actual ap won't submit when iv put it in the box. So I had to come through the ap store to do it. Plus the "tell us more" boxes you can't mark yes as it not there or you can't access it.
What's going on with the currency converter? Currency converter is the most useful part of all, to me, and now it's no where to be found. Fix it or I give it one star.
Haven't been able to open this app for over a month. Unistalled and reinstalled still got the same problem.
currency conversion that I'm always using and only reason why i downloaded this app is missing after the last update. please return it.
It would be a hands down 5 star, best calculator on Play Store had it not been a tad bit slow :( I'm not sure if the "fade in/out" was intentional, but it's definitely annoying. Also the loading (albeit a fraction of a second, but noticeable enough with the loading refresh sign) whenever you tap on the history.
I would rate it higher except the app is always running in the background and is using data...there is no reason for constant running and data usage. Update: I sent a screenshot to the app creators showing it used 18+mb of data, so it does run and use data in the background...found this out with an app I had used to see what processes run in the background .
It does exactly want you want from a calculator, but additionally has great currency function. You can enter several currencies and it translates instantly a figure in one, to the equivalent in the others. Great if you need to work in more than one, or are travelling and want to compare prices. I use it daily.
forcing a toolbar is a step in the wrong direction. No one wants to have even more clutter added to their phone, and having a constant bar in the notification section is just horrible. If it were possible to uninstall this app I would, but for now I have to just force stop it and restore the app to the factory version.
I find this particular application to be extremely user friendly and I appreciate the fact that the people/person who developed it was intelligent enough to come up with and apply the feature that allows the user to view the answer to any given equation that they're attempting to calculate BEFORE or without having to press the = (equal) button! It's so simple but in my opinion genius! I love it. Thank you for making this available and free also. I'm definitely a satisfied unpaying customer. :•)
I have DISABLED this deceptive, data hijacking, private information stealing excuse of an app. I only kept updating it because it was bundled as a default app in my phone with no option to uninstall it. First it started wanting WIFI INFORMATION. Then it started showing a PERSISTENT NOTIFICATION (which could be disabled only by changing an option in Settings, which lies 90% users use it). And now, it wants access to all of our PHOTO, MEDIA, STORAGE and FILES? Why does a caculator need all of this?
there is a huge glitch, and it appeared at the top of my sreen without asking and i cant get rid of it. first of all, when you go into the main menu all of the names and icons are mixed up. instead of "length" and a "ruler" icon, theres a machester united logo and the words "speed". This is similar for all of the measurements. please fix it!!
Full of ads constantly asking to review it even though you already have and always adds itself to homescreen the most annoying thing is it can't be deleted either so bloody stuck with it. Other than that as app came with my phone then loose the adds fix the automatic shortcut to homescreen and it would be a good app but as it is its unusable as adds constantly fill the screen whist your half way through calculations
Not much to say, it is a good app, it is preferably and probably better than the automatic calculators that are added on your phone. I do think that it is better to use scientific calculators as students and friends tend to lie about using a calculator and then using their phones for irrelevant things.
Perfect for budgeting when all you need is a quick add, subtract, multiply, etc. Also adding up work hours and wages, as mine always vary. I super appreciate that it has a history feature, so I can look back if I forgot something. 5 stars, definitely!
Let me ask you a question. Is a calculator a critical part of your job? Do you not have a calculator? Then this is the app for you! This app will put a permanent notification on your top bar, so you have easy access to a calculator, for all your basic math needs that come up soooooooo often. Seriously though, this is hot garbage. I would absolutely uninstall it if I could. Get rid of the notification or let me get rid of this junk
Quick, Easy to use. Conversion Calc good all conversion across the table is easily listed, instead of converting all measurements across the board, from weight, length, temp, mass, cooking etc on metric table & all languages individually, to get an answer.
I personally dont understand this app. Its more than a calculator. Its also a ram cleaner ,booster etc. Others may love the various things this app can do, but i only want a simple calculator. When its enabled It slows down MY ph. ( Sorry to the devs, it is a great app), but its not for me, so i disable this app. My ph is cheap with low memory so somthing that runs constantly in the background is not good for me. But for others with the ram etc its awesome.
Well designed UI, clean and functional. BUT too much adverts, even while starting and app load time is comparatively slow. Apps start with full volume. And no one ay to one way purchase premium and disable ads.
Pretty darn good, wish theirs ratio as well other hard maths stuff.
Love my calculator... It works so great... I love the history saver... It's great!!!
Easy to use and very dependable, thx.
The calculator is good, but could use some more improvements. It doesn't store a 5 or more digit in memory, but has history of calculations... More help would be helpful.
Pleasant and easy app to use, in addition to a calculator, I also am able to use currency converter and a number of other options are available too; e.g. all the measurements and metric conversions anyone may want to use in daily calculations and measurements. I like it.
A very useful app just wish there were no ads or premium version to remove ads. This is definitely better than google standard calculator. I don't care for the boost nor the third party game feature.
Best calculator app that I have used/found. Has some really great features.😍😎 Only complaint that I have is no custom sort order when adding more currency types, can be hard to find a currency if you don't know what it is called (eg, UK pound is called GBP)🤔 it would be handy if there was a "sort by country name" or something. I now have issues with the boost feature rubbish, why do you need to interrupt us with useless rubbish?
It's a good app. Does pretty well on many situations Just... I would like it to have support for landscape mode (cause I use my cellphone that way from time to time) and more functions, to be even closer to a scientific calculator
A calculator app that pesters you to do this and that while you're trying to do your work. It keeps asking me to add buttons to my notification area or whatever. Guys, I turned that off on purpose. You don't need to remind me. One star in the hope that phone apps stop being such a clown show.
This used to be a 5⭐ app, then all the advertising started & the games! Omg if I wanted to play games I wouldn't be using my calculator. I now spend more time watching ads /games than I do calculating. Please fix this issue & go back to the awesome 5⭐ app it once was.
When i open App every time its blink and doesn't open. please resolve this issue.
I believe it's a good Calculator app. Has everything you need on it. It good you have a use history, so you can check over what you have worked out, especially when working out finances/budget etc. So Thanks to the app makers. Any adverts don't worry me much, as you just keep your phone data off while using it, & it keeps them at bay. All good. Regards, Darren. New Zealand.
