I second that motion

mis there anything I/we can do to help find someone who can do this?

The first thing I'd need is to update the android app so that it uses the newest APIs. There's been some reports of issues with power saving and android 8 ignoring wakelocks. I looked into it and I was never able to fix it (or reproduce it on my device).
Once that's done, I want to unify the PC version and the webapp, a full rewrite using Electron (the android version will keep using java, but it will be updated so that it has the same sound as the PC version). This is especially important for mac users, since there's been reports of the mac version not working properly on newer versions of macos. Apple has always done its best to make cross platform development as shitty as possible, and frankly I just gave up: if someone can fix it, good, otherwise macos can go fuck itself.
Finally, the SINE preset format itself should be improved: it needs better preset descriptions as mthakurr said, support for different types of noise, and maybe more.
Right now SINE just doesn't have enough users compared to some of my other projects to justify the enormous effort of basically redoing the whole project using more modern technologies. If someone wants to do it, I will be 100% available to them and help them do it. The project is fully open source so anyone can try.

The android version needs an update to make sure that everything works and looks pretty on newer versions of the OS (this will probably require some wakelock magic when increasing the API level to 26 or newer). Right now it works though.
The macos version desperately needs an update because it barely works.

Feel free to ask around if you want, no offense taken.

thank you,  I hope this works out.

Atropine please contact me if you want to give it a try. info@fdossena.com

fingers crossed

Okay so does this mean that if all goes well SINE will be on the in the Apple Store to?
Does this also mean that a maintainer has been found and SINE lives on?

Hey there fellas, I'm a freelancer software engineer that has been using this piece of heaven for about a year and all I can say is THANK YOU, the work you guys put in this is wonderful.
This may seem weird but reading this makes me happy, I'm a strong believer in the union of the self, and everything related to vibration and quantum mechanics, and, reading this post, has given me a spark of light on what to do next.
I currently have a job-project ongoing, which I probably will be free from in a week or two, after that I would be very, very glad to help on anything you guys might need, being that porting the whole app to Electron, actually, I can see a lot of frameworks on the horizon(looks at flutter)
Anyways, I love Python and Node but I can work with pretty much anything you put in my hands.
I would love to hear from you guys, hope I'm not too late, please give me the fastest means of contact so we can get in touch.

Danzera, that's great to hear, I was afraid there was nobody with the skills and time willing to maintain this great app.

I hope besides maintaining and porting to see the app see more functionality, it would be really nice if it had panning functionality (like one track 20% to the right and the other 80% to the left ear), that and some of my presets go beyond what is possible in the editor (higher and lower frequencies) I hope those will still work (I used an xml editor to do that, they can be opened and used in the app but not in the editor). Another thing that has been on my mind is, the list of presets is currently really long, categories/tags would really clean things up, especially since it's an ever growing list.

Version 1.8.7 is out now.
No major changes really, just some needed maintenance:
* Macos version works again: thanks to our new member and friend ahabhyde, who is also a java developer but has experience with macOS, the SINE app now works on newer versions of macOS (we tested mostly on mojave, since it's the latest one). Any subsequent update on this front will be done by ahabhyde, not me.
* The computer can no longer go to sleep while the player app is running (on all platforms)
* Minor changes

An update for the Android app is also coming, so hold tight.

Once this necessary maintenance is done, we can think about new features, and maybe unifying the codebase.

Yay!  Thank you everyone for stepping up to save this wonderful app and updating it.  Good to hear there is an Apple version.  Most of the people I tell about the app have Apple products.

Greatly appreciated.

If you want to delete a preset all you have to do is go to your preset home let's say u want to delete Theta in your presets home select Theta and in the upper right corner are three dots touch the three dots and the drop down menu select delete touch delete and the preset in this case Theta will be gone.
