DNA app store Helix.com is having a $100 off promo.
The cheapest "app + test kit" bundle is SlumberType, which is now $4.99 and it tells you whether about how your DNA affects your sleeping habit. Second cheapest is the Vinome app + test kit. It'a $9.99 and it gives you wine recommendation based on your DNA.
The idea of Helix is that you only need to do one DNA test, which according to Helix.com: "use Next Generation Sequencing technology to read your DNA, which unlocks up to 100 times more data than typical at-home DNA tests on the market today". After that one test, you can purchase apps from the Helix platform, kinda like what Apple App Store does.
Promo ends tonight, 11/9.
These are also on Amazon.
