Face it. You’re not a kid anymore. It’s time you grew up, traded in your hot hatchback for a minivan, and started a family. Timing is of the essence when it comes to planning a pregnancy: if you happen to be in Japan and subscribe to NTT DoCoMo, you may want to consider the Mitsubishi D702iF, a cell phone that “will keep track of a lady’s biological rhythm.” Remove the marketing speak and what you get is a mobile that monitors menstrual cycles, informing you of the optimal time for conception. Outside of this feature, the D702iF is pretty blah. No word on pricing.
