Convert between calendar dates, ordinal dates, ISO 8601 dates, ISO week dates, Julian calendar dates, Julian Day Numbers, and Unix timestamps.

For an instant glance, enable the optional app icon badge to show the current day of the year. Badge updates are silent and do not create banners or sounds. Notification permission is required.

Okta’s achievement of an Impact Level 4 (IL4) conditional Provisional Authorization (PA) provides a next-generation security architecture that centralizes and secures access to mission-relevant resources for approved users – anywhere, anytime. The LeaveWeb Mobile App provides the following features: * The leave member can submit leave for themselves, but there is no ability to submit leave on behalf of another in mobile. * Leave submittal through return on leave types A, R&R, D, F, P, and T with upload ability.

Verdict

The call

The clearest difference is rating: Julian at 4.8 against LeaveWeb Mobile's 2.5. Julian also leads on review sentiment (67% vs 31%) and ratings volume (4.7K vs 12). LeaveWeb Mobile's advantage is in-app purchases (none vs 3) and iOS requirement (15.1 vs 17.0). On price, update cadence, ads and device support there is nothing between them.
