If you look under the Logs\ directory of the Twaddle directory there will be a bunch of files containing information. If you’re able to send those files to support@twaddle.mobi there might be some clues into your problem.

Does refreshing manually work? There’s a possibility that with a setting of one minute intervals you’re making too many calls to the Twitter servers (especially if you’ve got a desktop client running as well). Twaddle only performs 2 background tasks at once – with a setting of one minute refresh intervals and ~6 background tasks being refreshed every minute, it could be that your phone can’t process them fast enough before the next minute gets added to the queue of tasks. The “Friends” task in particular can take a long time if you have many friends. I’d avoid using one minute as your device is very unlikely to be allowed to fall into the sleep state so you’ll really eat through your battery. A setting of 5 minutes is probably more realistic and less likely to run into either of these problems.

Within Twaddle if you go to Settings (The S on the far right) and then Notifications there are options for Pop Ups and Vibration for each of the public timeline, direct messages and mentions. Does ticking those cause your phone to vibrate?

Will definitely work on audio notifications for a future release though.

In a future release I’ll add the ability to have audio notifications. As I always have my phone on vibrate, they’re not high on the list of features :) But I’ll see if I can squeeze them into 0.3

If so – then no, it doesn’t currently support it. If you can provide me with some links to documentation on what you mean then I can have a look at implementing this.
