Smartphone apps have really caught on the last few years, with many of them becoming indispensable to everyday living.
But at the same time, technology has a way of getting under people's skin and making them think twice about using them in the first place.
These apps no doubt have been very good ideas when they were being conceptualised on the drawing board. But it really depends on whose hands they fall into and being annoying is just the start of it.
Here is a list of 10 apps -- from the well-designed to the utterly useless -- that never fails to annoy when used by Singaporeans:
This app is a messaging service that allows anonymous messages to be sent and received.
But it only works well if there are numerous participants in the chat as a user can see who he or she is sending a message to, but the recipient can't see who sent it.
When used in other countries as a way to bully and gossip without a care, such as the United States, this app is a cause for concern, where there are fears it might be misused by teenagers.
However, ferreting out who wrote what in Singapore is less difficult as Singaporeans tend to type messages in idiosyncratic Singlish words or phrases, making it not as difficult to identify who said what to whom.
Well, would-be anonymous bullies, you've been warned.
This app allows pictures to be sent for a few seconds before it self-destructs.
However, photos can be screen-captured before they disappear for good.
So herein lies the problem: If you're using this app in Singapore for the purposes of virtual hanky panky, you might be in for a shock.
Singapore is a small country. Any visible landmark, foreground or background detail can be captured in the picture, used as markers for identification and even traded among people on forums.
And you could be traced using any possible digital trail on your Facebook or Instagram account.
