SyncCal allows you to share your iOS calendars (e.g. iCloud and Exchange calendars) via Google Calendar with other people. E.g. if you would like to share your work calendar with your family, you can do it this way. And if you (or your employer) doesn't want the events' details to be uploaded to Google Calendar, you can only upload empty events instead, so that your family knows at least the times of your events. Just install SyncCal, enter your Google Calendar account, select which calendars should be synced and tap "Start". Afterward it will copy the selected calendars into new calendars in Google Calendar. It will also automatically keep them up-to-date by using background refresh and push notifications. It can also be configured to automatically sync when you leave your workplace. Just turn "Sync when leaving this place" on when you are at work. SyncCal will save the location and afterward it will automatically sync every time you leave your workplace. iOS' birthday calendar can also be synced into a Google calendar this way.

Verdict

The call

The clearest difference is price: RealVNC Viewer at Free against SyncCal's $0.99. RealVNC Viewer also leads on rating (4.8 vs 3.5) and ratings volume (15K vs 22). SyncCal's advantage is iOS requirement (8.0 vs 14.0). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

RealVNC Viewer holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: RealVNC Viewer has 15K ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 72% of RealVNC Viewer's written reviews are positive against 76% of SyncCal's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

RealVNC Viewer ships an update every 2 months, SyncCal every 3 months. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
