A really great tool kit that everyone can use! Truly, a fantastic job guys and gals. My only issue is that it crashes at some point every time I open it.... think you could fix that for me??!!! It's so good I'm still giving you a 5 even though it crashes...that speaks volumes:)

Z70%
by Z####:

the tool app looks useful on installation. did a quick browse & realise there isn't any conversion for "cup to ml or gram" in the unit convertor. if this was possible/available, i would give it 5 stars as i often need this information when baking/cooking.

A70%
by A####:

The clothing size convertor is a plus. But why is the interface so laggy? I am using the latest processor and have enough free ram. Would be great if you can integrate material design and make the interface quick.

Z70%
by Z####:

Please note that I'm using a sony xperia zr with 2gig of ram and a quadcore chipset with absolutely no problem with any other apps. The app needs more optimization and better UI to match the quality of Line chat.

by Z####:

The functionality of this app is very versatile, I just wish the regular North American calendar was featured along with the Japanese version. Hopefully, it will be added in the near future. =)

Z70%
by Z####:

I download thus because im extremely bored with in built organizer app. But some of the funcion doesn't work like the magnifying glass can't focus amd can't turn on the led flash ligjt, and also its a bit slow. But still its a great app. I suggest you add theme like the messanger

O70%
by O####:

Useful, circumstances! But better have regional country options. Coz based on other country culture will have more languages selection. And after updated when i open QR code reader will automatically closed down the app. Please fix it also.

Z70%
by Z####:

This app is so utterly incredibly useful that I divorced my wife and moved in with it! I'm going to marry this app in the summer. I haven't found one thing that this app can't help me with. Thank you x

My transparent protector doesn't work.. it crashes every time i wanna open it... please go throw the matter as early as possible.... thanku..

N70%
by N####:

So many features - so useful. No more looking up inches to cm or mm anymore. I just pull up line tools. Love the magnifier with a light! One of the most useful apps I have & am sending it to friends.

Z70%
by Z####:

Qr code is not working properly if I open it, line tool suddenly stopped working and it happens with other tools also.... It needs to be upgrade... Then only it can be good to use...then I will give 5 star rating... Please upgrade it...

B70%
by B####:

Cute app. Suggestion: add day or time countdown calculator . Like for example how many days from today to three weeks from now. :)

Q70%
by Q####:

There have been many times I would have been in big trouble without this app!

Y70%
by Y####:

I like it, but it's not perfect. Many details bother me. The first and obvious one is why doesn't the Back button work on the main page? It really needs a black theme as option... The app itself doesn't allow shortcut activity to each utility to be created with advanced launchers like Apex Launcher and similar on the home screen as shortcut (this is useful!) . Japanese Calendar??? Why not make it automatically detect the type of calendar is needed? Besides that it's a toolbox rich in functionality.

J70%
by J####:

Just a small warning, it was made by an Asian company, so things like the barcode scanner don't work for American barcodes.

I70%
by I####:

Using xiao mi 3 on this app especially on protractor is too laggy ,will give a five star if you fixed it

T70%
by T####:

Sometimes it works fine and when it does I love it, but more often than not, it stops working, and occasionally it resets my LG G4 :(

Y70%
by Y####:

Which " tool" here needs to access my contacts or needs to know all about my WiFi connection and who's connected to it? I was just looking for an all in one toolbox with a ruler, compass, protractor, etc. Geesh! Too obvious marketing guys...

Y70%
by Y####:

Clothing size is wrong and what about adding Australian sizes for a start? The clothing conversions are useless to me. Japanese Era/Age function was usless to me as I only speak english - as was the Japanese calender.

Y70%
by Y####:

But after I've added my favorites evry time whn i exit and go back in the app my favorites have to be reset. frustrating. plus it'll be great if there's a torch light widget. it's inconvenient to fiddle with so many stages before torch light can be turn on. Till thn, I'm uninstalling.

All frequently required tools supported. Favourites option improves usability. Minor gripe is that the Compass has directions written in Chinese or Japanese (pardon me there).

by W####:

I've tried to install this app for several times but it says " error. Could not install on USB storage or SD card" can you even believe that?!?! Well, firstly I'm sorry if the error was caused by my phone, and honestly, when I saw the pics and description of the app, I would love to install it.. But because of the errors, I turned out felt dissapointed. If the error was caused by this app itself, please fix it. I'm sorry if this annoy you guys but please fix it if the error was caused by this app. Thx

Amazing variety of useful tools for measuring, converting quantities, calculating exchange rates, etc. Very helpful when cooking, sewing, travelling & shopping. Tools are also very user friendly and easy to use! Great app!

But it would be better if i could have them as individual apps so I don't have to open folder to use the tools. How about some widgets.

Y70%
by Y####:

that protractor is slow and not responsive. Supposed to be smooth, like Smart Tools'. The size converter is very useful.

U70%

App keeps forgetting My favorited tools every time i open it..tools r perfect in measurements

Y70%
by Y####:

I love this collection of tools and measuring devices. I've been looking for something as comprehensive as this set of tools for ages. And they're free! Thanks so much for your contribution to the app market. Well done!

K70%
by K####:

All in one tools in here, so it's not necesarry to install many apps for each function

Q70%
by Q####:

There is a dizzying array of tools available in this app! Very useful. I would recommend adding ability to snap to standard distances/angles for ruler/protractor but they work very well otherwise. Keep it up! Nice work!

Change the language of the compas from chinese to Arabic alphabet. You should include a lux meter.

Q70%

It eats our time .It shows u will get talk time. If send our mobile no and operator , it replies something went wrong. Idiotic

Z70%

Amazing everything is wonderful, that calculator and flash light the stop watch keep improving this app its great indeed.

G70%
by G####:

Would be even better if had a money/currency converter ;-)

G70%
by G####:

Many tools in one app and all with cute touch. How can't it be awesome? They are so useful, especially for cooking. But I just don't understand with those Japanese tools like the Calendar and Era/Age, since both are in Japanese language. I want more tools that can be used globally.

S70%
by S####:

People that I know are saying - Nah,It's worthless,need more tools and it's not so accurate,blah,blah,blah I would say...My opinion is that the app gives you the set of most used & basic tools for simple,every day tasks,and if I'm not wrong,the developers had that idea also.About accuracy,while it's not 100% perfect, it's sure doing the promised & for those who are saying that the app is not easy to use..Go to to hardware store, buy some real tools and learn to use them:then rate this app again!!!

Q70%
by Q####:

I love that it has all these tools but some of the more critical ones don't work right. For instance the Compas is totally wrong (and I have tried it on 2 different devices and both reported the same). It isn't off by a little either. I pointed North and it said I was heading NE by 64 degrees. I sure wouldn't depend on this to guide me if I were lost. The level app is also really bad. Again I used this on 2 devices and both were off. Although this time they weren't off by the same margin. It was fine at level but once you were off level it was incorrect. I had the phone almost vertical and the level was saying that I was only a hair off level. Otherwise the app has alot of gadgets in one place which I love. If they get the gadgets to be accurate I will surely install it again. Uninstalled.

Q70%
by Q####:

But in Sony Xperia Z3 the compass responds very slow, even my old Asus Padfone 2 is very smooth with the compass.

H70%
by H####:

Unit converter is awesome. Only criticism is that it's a little bit slow when switching between tools sometimes but it's barely noticeable. Clean, intuitive UI and a ridiculous amount of tools that I didn't even realize I needed until today. Translation for calendar and era/age would be appreciated.
