A tool for players who give the calls for their alliance in mobile strategy games. This guide explains, step by step, what it does and what to do after you sign up. It’s written so that even people who don’t know the game can follow it.
In a word, it’s a tool that “tells each teammate their own moment to press, with a single call.”
Say four players want to land on the same base at the same time. But their cities are in different places on the map, so their march times to the base differ. One takes 3 minutes; another arrives in 45 seconds.
If they all press together on “3, 2, 1,” the closest players land first. To land at the same time, you need to “press earlier the farther you are, and later the closer you are.” The moment to press is different for each person.
Player A march 3:00 → press at 21:00:15
Player B march 2:15 → press at 21:01:00
Player C march 1:30 → press at 21:01:45
Player D march 0:45 → press at 21:02:30
↓
Everyone lands at 21:03:15
Doing this subtraction for every player, to the second, over and over during a live battle is too much for a person. With CommandClock, the organizer just presses the call once at the moment they want, and the tool calculates the landing time. The tool also builds this table and sends each device a countdown just for that player.
When you’re lining things up to the second, a phone clock that’s a few seconds off ruins everything. CommandClock uses the server’s time as its reference instead of each device’s clock, and also subtracts the round-trip network time to correct for it. Users never need to reset their clocks.
Everyone who joins first chooses their role. There are only three.
The person who gives the call when it’s time to rally. One per group is enough. The officer’s screen lists every member’s departure time.
The player who sends out their own rally toward the target. Their screen shows “Depart in ○ seconds,” a countdown just for them. March times differ by player, so they enter their own march time once at the start.
Up to 6 can register per group (squad).
A player who doesn’t start rallies but joins a rally leader’s rally. There’s no limit on the number, and no extra charge no matter how many join.
In the pricing section, choose a plan and pay by card. When payment is done, the completion screen shows three things: the URL, Room ID, and join code. The same details are also sent to your registered email address.
The Room ID and join code are your group’s own key. Other customers can’t see them.
Send the URL, Room ID, and join code to your members by chat or similar. No app installation needed; they can use it by opening it in their phone’s browser.
*The built-in browser inside social media apps may not work properly. Choosing “Open in browser” is the safe option.
Opening the URL shows a screen for entering the Room ID and join code. After joining, each person chooses their role from “Officer,” “Rally leader,” or “Joiner” and enters a name. Rally leaders also enter their own march time.
What you enter is saved on your device, so next time you just choose.
On the officer’s screen, press the call button when it’s time to rally. At that moment, everyone’s screen starts moving on its own timing. Then each person just moves the moment their screen says “Start.”
Seeing it move is faster than reading, so take a look first. The 30 seconds from giving a call until everyone lands are in the demo on the top page.
Example of the copied text
[Rally time] ○○ Alliance Squad 1 Landing 21:03:15 Player A Depart 21:00:15 (March 3:00) Player B Depart 21:01:00 (March 2:15)
Useful even when members can’t open the tool. Available on every plan.
It also works on a phone. But the console puts three alliances side by side on one screen so you can compare them while giving calls. For readability, speed, and ease of tapping, a PC is best. On a phone, the alliances stack vertically, so you’ll be scrolling up and down while you operate it.
A guide to the minimum you’ll need.
The player screen that members use is designed for phones.
When the enemy attacks you in a chain, slipping your own troops in between to defend is reinforcing. Set how many seconds before the last landing to send them in, and a signal worked backward from that time is sent out. This is an officer feature, so it’s available on every plan。
The plan boundary depends on how much of this nesting you use.
Each ■ is a rally leader slot. Up to 6 per squad, and 2 squads per alliance. 36 slots in total.
Joiners don’t use slots.There’s no extra charge no matter how many people just join rally leaders’ rallies.
