Keepster offers an easy-to-use and convenient way to archive, view, organize, and search through text messages - all at no charge. Although iCloud or macOS can back up the Messages app, the backup can only be used to restore your messages to an iPhone or iPad. The backup itself cannot be exported to a desktop or laptop computer for easy access. Keepster overcomes this hurdle in style, allowing you to offload long text message threads from your phone, for example, while preserving full access to them. All of this is a prelude to Keepster's moneymaking business, which is to sell memory books built around saved text messages. The free service is worthy of payment in its own right.
