Video magnifier apps and phones
These apps can be downloaded to compatible smart phones and are designed to give a magnified image on the smart phone's screen.
Check the app is compatible with your phone / device and the operating system you have installed before download / purchase. Some work best on later versions of well known phones with enhanced autofocus cameras.
These apps may provide an alternative to a magnifier but you should take into account the limitations of relying on a mobile app. The following issues may prevent the app working:
- Hardware and network access limitations / having no signal
- Putting a phone on SILENT
- Conflict with other software/apps, task killers or upgrades to the operating systems
- Your phone's battery running out
- Not having your phone with you
Consequently users of these apps should not rely solely on them for magnifying important documents and instructions. You may wish to have a backup magnifying glass / device.
These apps may be updated periodically, users should independently check for new version of these application as there may be important bug fixes.
When downloading an app use only well-known app download markets. They significantly reduces the likelihood of downloading an app malware/virus. If you're interested in downloading a particular app, run an online search on its name (using a search engine) first to see what others say about it or to check for malware reports. Note that Apple retains full control over Apple apps and the way they actually run on its devices and vets each one before making them available at its App Store. View relevant references ‣
