People giving you a wide berth? Breathometer Mint is a handy gadget that lets you know when your breath is causing a stink.
Just blow into it, and it'll tell you the quality of your breath, and how hydrated you are, so you can take better care of your mouth. Better oral health will make your breath smell better, so you won't inadvertently ward off any admirers.
Sync Breathometer Mint to the app on your Android or iOS smartphone, and it will show you a load of data about your oral health, and make suggestions on how to improve it. It tracks your activity for both breath quality and hydration results, lets you export the data so you can share it with medical experts or your personal trainer, and gives you rewards when you hit your targets.
It also integrates with Apple HealthKit and has a leaderboard, so you can compete with your friends.
The device itself contains an electrochemical fuel cell, and connects to your smartphone over Bluetooth Low Energy. You charge it using the supplied microUSB cable, and it will last between 10 and 14 days before needing a recharge.
If you're quick, it can be yours for $89 (£59), which is $10 cheaper than the RRP. Though if you live outside the US and Canada, it will cost you $149 (£98). It's only been on Indiegogo for a couple of days, and has already hit its $25,000 funding goal.
