Get 4D results on your iPhone

I’m betting that this app will do well. Ong Jun Da has just released SG 4D. This app will allow you to:

• Check previous results (going back to 2005)
  
• Find out when a number last won anything

Free but ad-supported. Download app here.

Jun Da also wrote SG Pools, a free app that delivers football odds from Singapore Pools. Read an interview with Jun Da here.
