However, users repeatedly flag reliability concerns: OS compatibility breaks on newer macOS versions, incomplete/erroneous syncing with large data sets, occasional freezes or crashes, and aggressive upsell prompts with unclear free-versus-Pro features. Overall, it can be very effective for daily syncing, but reliability across complex or large-scale tasks and OS updates remains a risk. ### Pros - Incremental backups that copy only new or changed files, saving time. - Easy to use and beginner-friendly with a clean, intuitive UI. - Cross-platform support (macOS and iOS) and the ability to sync across local folders, iCloud, network drives, and external storage. - Detailed preview of changes before syncing, plus logging and conflict handling. - Flexible sync options (two-way, one-way, and mirror) enabling set-it-and-forget-it backups. ### Cons - Compatibility issues with newer macOS versions (e.g., Tahoe 26.2, Ventura 13.1) leading to failures or broken syncing. - Incomplete or unreliable syncing for large datasets (first pass misses substantial data; results can be inconsistent). - Crashes or the app becoming unresponsive during use. - Upsell prompts and confusion over free vs Pro features (frequent prompts to buy Pro and misleading expectations for the free version). ## Similar extensions and apps - [Sync Folders Pro](https://chrome-stats.com/d/id522706442) — 4.60 / 5 - [Sync: File Backup & Cloud Sync](https://chrome-stats.com/d/id945501464) — 3.70 / 5 - [Resilio Sync](https://chrome-stats.com/d/id1126282325) — 4.50 / 5 - [SynoSync](https://chrome-stats.com/d/id6762731663) — 5.00 / 5 - [4Sync](https://chrome-stats.com/d/id666270575) — 2.90 / 5 - [Sync with Files](https://chrome-stats.com/d/id6754183905) — 5.00 / 5 - [CumuloSync](https://chrome-stats.com/d/id6745569723) — 5.00 / 5 - [File Sync: Easy Photo Transfer](https://chrome-stats.com/d/id1588207923) — 4.10 / 5 - [Sync Shutter: SD Card Backup](https://chrome-stats.com/d/id6758906685) — 5.00 / 5 - [Möbius Sync](https://chrome-stats.com/d/id1539203216) — 3.80 / 5 - [Files n Folders](https://chrome-stats.com/d/id416409502) — 3.30 / 5 - [SyncDrop - Smart Photo Sync](https://chrome-stats.com/d/id6758571279) — 5.00 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id530573877)
