Well-renowned note-taking application Evernote has announced that it is instituting a few changes on its free Basic, Plus and Premium service accounts starting on June 28.

The number of computers, smartphones and tablets synced to Evernote Basic account is now limited to two, while its Plus and Premium tiers receive price hikes "for new subscriptions." Basic users and current subscribers of Evernote app are given some time to adjust before the changes become effective.

Subscription for an Evernote Plus account will now be more expensive by almost $3. It will now cost users $3.99 per month or $34.99 per year. An Evernote Plus or Premium account is needed to sync more than two devices.

The monthly price for an Evernote Premium account has gone up by $2 to $7.99 from the previous $5.99. Through the Premium account, users can now upload up to 10 GB of files. Moreover, this account features a business card scanning functionality and a searching and annotating tool for PDF files.

A passcode lock feature has also been added to the Basic accounts. This one was only previously available for Plus and Premium accounts.

In an official statement posted on Evernote's blog, CEO Chris O'Neill said that the changes were made as it plans to invest in new features in a bid to boost the user experience.

"Our goal is to continue improving Evernote for the long-term, investing in our core products to make them more powerful and intuitive while also delivering often-requested new features," writes O'Neill. "But that requires a significant investment of energy, time and money."

Users of the Basic account have been informed by email that they will have at least 30 days to adjust to the changes, along with a reminder that Paid and Premium accounts will still be able to sync the access to an unlimited number of devices, reports ZDNet.

Despite still being the most popular note-taking application in the market, 2016 has been a continuation of a rough few years for Evernote. In March, Business Insider reported that O'Neill replaced his entire leadership team, welcoming seven other executives from fellow tech companies like VMware, Logitech, Microsoft, Google, HP and Skype.

The company struggled with growing its revenue for months, even closing three of its 10 global offices, this is in spite of having notched 150 million registered users in 2015.

In the meantime, O'Neill adds that the company remained committed in keeping its products free of ads.
