Good Free App of the Day: Petralex - a hearing aid application

PetralexOK. There aren’t often times when I come across an app that makes me say “that’s so great – I need to buy it for so-and-so”. But I’m saying it right now about Petralex (and I’d say it even if it wasn’t free, but it is FREE). Petralex is an application that turns your iPad or iPhone into a sound amplifier. It’s as simple as that. Sometimes it’s the apps that seem simple that really end up being the most useful.

And did I mention that Petralex is FREE?

If you would like to download Petralex from IT ForYou (Free, iPad/iPhone), please use the handy link below so they’ll know who sent you.

NO Ads IAP YES ExLinksNo ads or in-app purchases. External links to the developer’s site and links to iCloud to sync profiles across your devices (can be turned off if desired)

Petralex3So why do I think it’s so cool? I don’t know about y’all, but there are folks in my life who need a hearing aid but aren’t quite ready to admit it. Or they have them and won’t wear them. Or perhaps they just have occasional situations where hearing is more difficult. Petralex can help with any of these.

Your iPhone and a set of earbuds wouldn’t let everyone around you know that you needed a little boost to help you hear. In fact, an iPhone with earbuds is so commonplace that they would practically be invisible in a social situation. So for those that are not quite ready to admit the medical need for full-time hearing aids or who feel embarrassed by wearing them, Petralex would be a socially acceptable compromise.

Or perhaps a person hears well most of the time, but in certain situations finds it a little more difficult to hear. Because Petralex allows you to set multiple profiles depending on your situations and surroundings, it can be used on those occasions that require just a little boost.
Petralex2You can read in the iTunes description below a lot of the more technical information if you want to see it. But what I can tell you is that it does what it claims and it does it well. Can’t ask for much more than that.
