The basic version of the app is going to offer four sounds, and you can choose which of them will notify you of the end of an interval. The sounds are: Gong, Piano, Organ, and Tick.
I think Gong and Piano will be the most popular. Gong is my personal favourite, but it is quite subtle and can be difficult to hear if you are using some Reiki music – that music is usually full of gongs! Piano is also a gentle sound, so can be more useful at times.
Organ is loud and insistent, like a sound of a ship in fog, but I decided to make it available anyway – for those who might be using a loud music during their treatment.
Finally, the Tick sound is very subtle and can be used in a complete silence without disturbing the patient.
You might prefer to use no sound at all, and switch on vibration instead, then keep the device in your pocket.
And of course, you can use different sounds for different intervals – it’s all up to you.
The premium version of the app will offer many more of different sounds – birds, frogs, thunder…
