I use Trello and have a specific list for ideas. It works for me because Trello is always “with me” as an app on my phone, on my desktop, or via a browser. I tend to have creative thoughts while out running and use speech to text to add a new card through the iPhone app without stopping.
I use speech-to-text on my iPhone inside a gmail draft notes on the go as well. I'll keep adding to the draft then email it to myself. I'll also use VoiceRecorder app that can do speech-to-text after the fact.
