iOS: There are few things more nerve-wracking for a parent than a sick or feverish child, and if your doctor tells you to wait it out, that's what you have to do. Luckily, Feevy is a new iPhone app that will help you track your child's temperature and progress, and report back to your doctor if things change. Feevy is on sale right now for $2.99 (to coincide with its recent launch), but it will probably go up to about $5 once the promotion is over. The app lets you track a child's temperature on a graph over time, so if you take their temperature every few hours, you can go back over all of your recent readings and see if their temperature is holding steady, trending up or trending down at a glance. You can also add things like medications that you've given them and when, so you make sure not to give them too much in too short a time period, and add notes about how your child is feeling at various intervals.
The app is universal, so if you have an iPhone and an iPad, you can use it on both (and sync with other family members) and you can also track multiple family members as well (even adults, if you want!) so you don't have to worry about mixing up information for more than one child. Best of all, once you have everything logged, you have one package you can show your doctor the next time you visit so they can see everything you did, when and how it all turned out.
