Book Depository - Buy (physical) books without minimum order and shipping fee.


TransferWise - Send money with the best exchange rate (around 1% loss only). I use it to remit between USD and SGD and it works perfectly. Sign up with my link to have your first transfer FREE ($0 fee, 0% loss)!

UberEATs - The Uber for food delivery. Get $10 off your first order with my promo code eats-uberjunda123 .

oBike - Rent a bicycle from anywhere in Singapore, and you can park it anywhere as long as not illegal or obstructive. The first 3 rides are free.


The Entertainer - Pay a one-time $98 for the year (price could change every year), and you get lots of 1-for-1 coupons. The deals are mostly good mid/high end restaurants, but also have regular eateries such as Dunkin Donuts and Yoshinoya. I easily saved $150 in the first 2 months.

Groupon - Groupon is still a good place to find good deals, though it is no longer innovative, and deals are getting boring.

iOS Apps

SG Radio - My radio app with all the Singapore radio stations! I used it every morning and evening on the train and bus.

VLC - Watch offline videos support various formats including mkv. I usually download videos from youtube on a computer (see youtube-dl below), then transfer it to the app on the phone.

Medium - Read articles

I have omitted apps that were already mentioned in other sections such as ShopBack, Uber, etc.
