Evernote is one of the most popular note-taking applications going around, but a revised pricing structure for paid plans and a new set of limitations for free users is sure to upset some long time fans of the service.

The recently announced changes will have the biggest effect on free users. The Evernote Basic plan, which is the platform's free service, has introduced a device limit that cripples the awesome functionality that Evernote provides. Free users will no longer be able to sync their notes with every device they own, as the Basic plan now limits users to just two devices.

Evernote is bringing its passcode lock feature on their mobile app to the Basic plan, but that's not exactly decent compensation for users who will be locked out of accessing their synced notes on a third device. Those who are currently over the device limit will have 30 days to "adjust" to the new restrictions.

As for paid users, Evernote is increasing the price of both the Plus and Premium tiers, which offer 1 GB and 10 GB of note upload space respectively, as well as no device limit. The Plus tier is now $3.99 per month (up from $2.99) or $34.99 per year, while Premium is now $7.99 per month (up from $5.99) or $69.99 per year.

Some of these changes, particularly the device restrictions for free users, could convince Evernote users to switch to a competitor such as Microsoft's OneNote, which offers similar functionality without the limits. Evernote does say the changes to pricing structure will help them invest in their core products, but it might come at a cost of users.
