1Checker Website Design

1checker review

It is hardly possible to find the website design that would be more low-tech than the one 1Checker owns. You won’t see any eye-catching elements except for the 1Checker logo placed in the top left corner of the homepage. Being an educational web page aimed to render proofreading services and improve the language skills, it doesn’t need to pay huge attention to exquisite website design or focus on catchy web elements. However, in the XXI century, a highly technological interface able to ensure intuitive navigation and comfortable placement of the content blocks is a must. It seems that the given platform has chosen to ignore these requirements and paid its price, as such negligence has downgraded 1Checker rating a lot. Overall, 1Checker is quite informative: all the necessary information can be found in a blink of an eye in the corresponding sections of the main menu. Registration is fast and easy and will take not more than 2 minutes. To make it even faster, you may log in using your Facebook account. 

1Checker Quality

Despite all the pros 1Checker can boast of, the questions like ‘is 1Checker scam’ keep emerging. And there are many reasons for this. According to the numerous 1Checker reviews that can be easily found online, the results of its work aren’t as accurate as they are expected to be. While completing the check, the service considers some 100% correct phrases as incorrect. At the same time, some very obvious mistakes are usually missed. This fact is a clear evidence that the 1Checker software is somewhat obsolete and needs to be updated. If we talk about the time needed to complete the proofreading procedure, it mainly depends on the size of the text you are going to check. Despite the fast speed, its inaccuracy in completing its direct functions may serve the users of 1Checker a dirty trick, as, taking into account these drawbacks, the question of is 1Checker reliable seems more than relevant.

How Much Does 1Checker Cost?

As for the 1Checker prices, there is nothing to say, as this platform renders its services on a completely free basis. There is no premium subscription or any other options that could be used as additional ones for extra payment. The no-fee principle of the website can be easily explained by the desire of its developers to glean as much data as possible to improve the operational algorithm of 1Checker and increase its rate of accuracy. However, free usage is possible only in case you are an individual user. If you represent a company or organization and would like to learn about business opportunities 1Checker ensures, you should contact the customer support to get all the details. Most likely, the business package includes some extra functions and isn’t free of charge. But 1Checker website doesn’t provide any information regarding this issue, so it is better to ask their manager directly. 

1Checker Delivery Time

1Checker ensures instant proofreading results. Usually, the time when you can get feedback on your writing check depends on the size of the text you would like 1Checker to edit: the longer it is, the more time is required to proofread it. According to the information provided on the website, 1Checker undergoes constant updates and improvements of its software. There are no definite deadlines for updates, however, they are quite regular and increase 1Checker performance a lot.


On such a serious stage of paper writing as proofreading, anyone would like to have some guarantees that the service they use is reliable and professional enough not to play a mean trick on them. 1Checker, however, cannot provide any guarantees to its users. Moreover, taking into account the information indicated on the official website of the service, the software of 1Checker is far from being perfect. The platform admins are aware of the multiple mistakes of the program and keep working on its upgrade since 2010 – the time when the service was launched. 

In Case You Need Help From 1Checker

Unlike many websites of this type, 1Checker doesn’t feature a decent customer support service. In case of any questions or remarks, there is only one email that can be used to contact admins. There is neither information if you can get a response to your email nor any other option to use to liaise with the person who can help you in case you experience any problems with 1Checker. However, the website offers quite an informative FAQ section where it is possible to find the answers to the most frequently asked questions.
