Polaris Office review

Polaris Office is a free cross-platform suite that matters most to people who receive files in many formats on a phone or tablet. On the US App Store, Polaris Office Corp. lists support for DOC, DOCX, XLS, XLSX, PPT, PPTX, PPS, PPSX, TXT, HWP, HWPX, ODT, PDF and CSV, which makes it one of the few suites here that opens Korean Hangul HWP files. Apps cover Windows, Mac, Android and iOS, and a web office edits documents in the browser. Polaris Drive is the default cloud, but the app also connects to iCloud, Google Drive, Dropbox, OneDrive, Box, WebDAV and FTP, and the interface comes in 18 languages. The free version is real but limited: Polaris says some features depend on cloud usage or subscription level. Paid tiers on the App Store start with the Smart Plan at $3.99 per month or $39.99 per year, followed by Pro at $5.99 per month and AI plans from $12.99 per month, with a separate ad removal purchase. That plan list is busier than most competitors here.
