Scoot airlines. They sound OK, operating out of Singapore. But, no. their app simply does not work. My reference was not recognised so that was futile. I discovered upon checking-in that )without notifying me) Scoot had operational issues and cancelled my flight leaving me stranded at Singapore overnight without accommodation. They would not assist with booking accommodation and their refund will take, quote, '30 business days (that's 6 weeks in laymans terms) to be returned to me. So they take my money instantly upon booking a flight and then to add insult to injury will take 6 weeks before I get my money back. I would say it's likely I'll need to chase them when the refund fails to appear in the promised timescale. As I say, avoid avoid avoid.
