Ultimate Zmanim doesn't stop with the daily zmanim - it also lists chagim, the weekly parashah for both in Israel and out, candle lighting times, and daf yomi. Today's zmanim fade out as they pass, so you can tell what's next at a glance. Ultimate Zmanim also runs on Apple Watch, so you can get notifications, and information about the next upcoming zman right on your watch. With Zmanim Alarms, Ultimate Zmanim can remind you of important zmanim throughout the day. Shema, t'fila, and weekly candle lighting are all covered. Ultimate Zmanim supports printing of the daily Zmanim via AirPrint. You can use this to hang them up in public places, such as your shul, school, or mikveh.

You can also drag in either direction for convenient access to the previous or the next day. The timeline also supports both the Hebrew and Gregorian calendars. Open the date picker to switch between them. Ultimate Zmanim will remember your selection across app launches.

Verdict
The clearest difference is rating: Daven at 5.0 against Ultimate Zmanim's 4.3. Daven also leads on review sentiment (100% vs 78%) and update cadence (every 4 days vs every 2 weeks). Ultimate Zmanim's advantage is in-app purchases (none vs 3) and ratings volume (131 vs 11). On price, ads, monetization model and iOS requirement there is nothing between them.
