You can check the battery status of your phone and watch with your watch. Compatible with complications (automatic update). You can check the charging amount and charging status of the phone in a timely manner from the clock face. We will notify you by a notification when the charge amount of the phone or watch becomes less than the specified% or becomes full charge. The graph also displays the change in charge level for your phone and watch. - Set up complications with the watch app on your watch or phone. - The battery status displayed in the complication is automatically updated approximately every 12 to 60 minutes. The reason why the update interval has a range is that it depends on Watch OS. If the automatic update has stopped (for example, there is no update for more than 1.5 hour), tap the complication to restart it. In the iPhone app, the latest update time is displayed under the watch's charge status display. - Tap the complication to update to the latest status. - A circular complication can be assigned to the outer circle and the inner number to indicate the battery level of the phone and watch, respectively. -- I am a Japanese developer.

Clock24h

Clock24h turns the watch into a 24-hour dial. One full rotation is one full day: midnight at the bottom, noon at the top. A glance tells you where you stand in the day, not just in the hour. The dial is filled in with real daylight. Clock24h computes sunrise and sunset for your location and paints daylight as the bright region, night as the dark one. The seam between them drifts through the year. Far north or far south, where the sun no longer sets or no longer rises, the dial simply turns to all day or all night. THREE COLOUR SCHEMES Mies — white day, black night, one red marker. Corbu — warm amber day, slate blue night. Pesce — bright red day, bright blue night, yellow badges. Tap the dial to choose. Each row in the list is painted in its own scheme, so you pick by looking rather than by reading. COMPLICATIONS Ring — the day/night ring on its own. Ring + Time — the ring with the current time inside it. Mini Dial — the whole 24-hour dial, shrunk. KEEPING THE DIAL UP Clock24h supports the always-on display. Leave it open and the dial stays up, dimmed, refreshing once a minute. To keep it up for longer, open the Watch app on iPhone, go to General, then Return to Clock, find Clock24h in the list, and choose a longer interval. Raise your wrist and the 24-hour dial is what you see. DETAILS The second hand ticks once a second, sixty steps to the turn. A smooth sweep is available in settings if you prefer it. Sunrise and sunset are worked out on the watch from your location. Nothing is sent anywhere.

Verdict
The clearest difference is price: BatteryPhone at Free against Clock24h's $1.99. Clock24h's advantage is ads (none vs shown). On update cadence, in-app purchases, device support and iOS requirement there is nothing between them.
