About MobiOffice

MobiOffice (formerly OfficeSuite) is MobiSystems' cross-platform office suite for Windows, Mac, Android, and iOS. It bundles MobiDocs, MobiSheets, MobiSlides, and MobiMail with a free PDF reader and MobiDrive cloud storage, and opens and saves Microsoft Office, OpenOffice, and iWork files. It is sold as a low-cost alternative to Microsoft 365, with a free version, subscriptions, and a one-time desktop license.

Pros & Cons

Pros

Costs well under Microsoft 365, with a usable free tier and a one-time Lifetime license option
Strong Microsoft Office format compatibility for .docx, .xlsx, and .pptx files
Familiar ribbon-style interface that Office users can pick up without retraining
Runs on Windows, Mac, Android, and iOS, with cloud storage included on every plan
Mature product from a vendor with 25+ years in the market and a large mobile install base
EU-based vendor (Bulgaria), which suits buyers who want a European Office alternative

Cons

Feature parity differs by platform: MobiMail and MobiPDF are not available on Mac
Advanced PDF editing needs a separate MobiPDF subscription
No real-time co-authoring comparable to Google Docs or Microsoft 365
Some reviewers report crashes during heavy use and ads in the free version
Headline prices are promotional discounts, so renewal costs can be higher
