DENVER ( MainStreet) -- Turning a Kindle Fire into a child-friendly device isn't so hard, thanks to the Kids Place - With Child Lock, a free app from Phoenix, Ariz.-based kiddoware.It creates a walled garden where only parent-approved apps live. No more accidental video streaming, in-app purchasing or inadvertent banner-ad clicks. As with any good app, settings are easy to configure and offer useful features. Just check off "disable all wireless" (i.e. puts it in airplane mode) when the app is in use. Or enable auto-restart of the app if the kid accidentally exits the app. Kids Place is built for Android so if you're on a non-Kindle device, you can also enable phone calls or block access to Android Market. The app gives a child enough rope to swing on, but not enough to strangle himself: Control to draw, read book apps and play games with or without a parent nearby. I do wish it offered a way to allow certain videos already on the device. And, oddly, the apps are ordered not alphabetically but chronologically. I couldn't figure out how to reorder them, but to a child, does that matter? It would also be interesting to add a timer to set a limit on how long a child has access to the Fire in case the parent isn't, ahem, actively moderating screen time. The only thing stopping a child from accessing the rest of the Kindle Fire is a 4-digit code (or a reboot). You pick the code at setup and at that time, choose to email it to yourself. If you forget the code, which I did, you can remove the app and reinstall or let kiddoware know and they'll send you the master pin. My attempt to reinstall the app after forgetting my code got me stuck on the "Install" screen. Nothing worked and I couldn't find evidence of others having a similar issue. I finally turned to kiddoware for help (Yes, I wanted it back that badly). Paresh Joshi, who started kiddoware with buddy Robert Riley, patiently guided me via late-night emails through clearing the data for a few Kindle processes before I reinstalled successfully.
