The company says Instapaper Premium will help ensure it can continue developing and operating the app into the future.
Instapaper Premium includes:
● Full-text search for all articles in your account
● Unlimited Notes
● Text-to-Speech playlists on mobile
● Speed reading to get through all of your articles up to 3x faster
● An ad-free Instapaper website
● “Send to Kindle” using a bookmarklet or our mobile apps
If you decide to not subscribe to Instapaper Premium, you will continue with a standard free account without access to Premium features. EU users will get a free six month subscription as an apology for Instapaper's down time.
You can download Instapaper from the App Store for free.
