In first scenario, this timer is used for making voice recordings with voids.(In voice recordings with voids, each phrase needs to be followed by a period of silence of equal length, so that the listener can repeat the phrase, in a style reminding karaoke) So, to make a recording, start your voice recording app, switch to this app, press Start, pronounce a phrase, press Reverse, wait for signal, pronounce next phrase, and so on. In you want to record a comment which should not be repeated by listeners, after saying the comment press Start to restart the timer from 0.In second scenario, the timer works automatically. At the beginning, you specify the period by tapping on the running number field when it reaches the desired number of seconds. Then the arrow simply starts to periodically reverse its direction. This can be used for timing games, debates, dancing battles, even some formal talks or conversations between two people, where each side gets equal intervals of time for their activities. If your phone is between the two sides, the arrow shows the direction of communication, serving as a timing arbiter. You can modify the period any time by tapping on the period which is shown on screen in blue font. To "unprogram" the timer, tap the running field again.The voice recordings w/voids described above can be study materials for learning a foreign language, or some kind of affirmations which you record for yourself to be repeated daily as part of your wellness routines, or something else.To change the color of the arrow, tap on the arrow. To set the sound/vibrate signals, check the corresponding checkboxes.So, this timer is a tool for measuring equal periods of time implemented as a combined up & down timer. It first goes from 0 up, then reverses to counting down, goes back to 0, then automatically reverses back to counting up and so forth, emitting signals at turning points, thus producing pairs of equal intervals. Have fun using this straightforward and yet advanced timing tool!
