New and Noteworthy App Entries

DreamLab (iOS/iPadOS, Free)

Imagine if you could really make a difference and help to speed up time in the fight against Covid-19 and cancer.

DreamLab is a multi-award winning app from the Vodafone Foundation, in partnership with Imperial College London, which uses the collective power of mobile phones to fast track Covid-19 and cancer research. DreamLab exists to help find answers quicker and the more people who use DreamLab, the faster it works.

Medical research currently generates huge volumes of health data around the world every day, but access to computing power to crunch and make sense of this data is limited. Your mobile device contains a huge amount of computing power needed to run everything from email to music and video streaming apps, but is mostly dormant while you plug it in to charge overnight. DreamLab harnesses this processing power, of yours and thousands of other mobile phones, to examine such health data to look specifically at how existing drugs can be repurposed to help in the fight against cancer.

DreamLab taps into this invaluable resource to find more effective combinations of drugs that can be tailored to patients to improve treatments and save lives. As a Dreamer you can even choose which project to support and also select how much mobile data the app uses every month (or only on WiFi). Just one PC running 24 hours a day would need 300 years to process the data required to complete the project. However, 100,000 smartphones running DreamLab for six hours a night could fast track the job in just three months.

Guess the Rule: Logic Puzzles (iOS/iPadOS, US$0.99)

A square next to a circle? A red triangle on the left? One of each color? There’s a secret rule to determine which sequences of 3 colored shapes are allowed and which are not. Using your powers of inductive logic, you must predict whether each new sequence fits. Collect evidence, adjust your predictions, and guess the rule–it’s a lot like the scientific method!

Guess the Rule is easy to learn but difficult to master. Start with simple rules, but if you want to spice things up, try adding “and”, “or”, or “if…then”… You’ll find endless challenges, some of which are absolutely diabolical!

Play alone or with friends! Compete for daily high scores, or see who can guess the rule fastest in a pass-and-play match.

Roll The Bones (iOS/iPadOS, Free)

Roll the Bones is now a completely free app. By completely free we also mean ad-free and no IAPs!

Roll the Bones is a dice rolling utility with a clean, minimalist design. It lets you choose the number of dice you want to roll, the number of sides on the dice, and a modifier to add or subtract from the total of your roll. Your dice can have anywhere from 2 sides (flipping a coin) to 999 sides (attacking a horde of orcs) and you can add favorite sets of dice for quick access later.

Keep in mind that Roll the Bones is NOT A DICE GAME, but is instead a utility you can use to play games where you roll dice.

Sonar Islands (iOS/iPadOS, Free With In-App Purchases)

The new game from the makers of the award winning game FEER.

Sonar Islands is a MULTIPLAYER ONLINE game, where all relevant events happen in your ears.

On various islands you explore and discover, seek hidden TREASURES and conquer OBSTACLES. Every new island has a special atmosphere and a different gameplay. Do your best to fortify your islands and be clever enough to take the gold from your opponents.

  • Visit the ancient TEMPLE island, the ancestors built, where snakes are biting and down falling parts may block your way.
  • Take a trip to the JUNGLE island, watch abandoned lions on your way, but be aware of the tree traps, set up by the natives. You can go up, but there is no coming down.
  • The FUN FAIR island is a happy place to be. You can shoot toys coming towards you. Some carry a treasure, some carry a bomb, that's the risk.
  • The VOLCANO island is a chilly place, for some too hot, especially if you step near the lava flows. Ash and stone rain down due to the eruptions of terraforming, raise your shield to protect you.
  • In the MACHINE HALL you will meet the friendly robots from Feer, but this time you carry a stun gun to short-circuit their brains, at least for a while, till their self-repair is complete.
  • On PING island you will get a sonar device for orientation, send out a tone and the echo tells you, where to go. That’s good, because you may discover, this island is a labyrinth.
  • High up on the TREETOP island you have to deal with wind and mosquitos. The wind is really disorientating, leaves are rustling, while the mosquitos chase you. And don't fall, while balancing on the twigs.
  • On the ELECTRO island you face the invisible power of ELECTRICITY. Tesla coils sparkle round their high voltage, better shoot some metal confetti to divert the current. The nice thing here are catapult plates, they make you fly all over the island. A pity, that you don’t know where you will end up.

Happy vacation!

Sonar Islands comes with a tutorial, a training island and a story island. To get full access to the game, Sonar Islands offers a monthly and a yearly subscription. When you purchase a subscription, payments will be charged to your App Store account at the confirmation of purchase and will automatically renew unless canceled within 24-hours before the end of the current period.

Tooth Fairy (macOS, US$5.99)

Connect AirPods (or other Bluetooth headphones) to your Mac with a single click or keypress.

AirPods are great, but they don’t work quite as smoothly with Macs as they do iPhones. You can’t tell at a glance whether audio will play from the AirPods or your Mac’s built-in speaker, you have to dig into a Bluetooth submenu to connect, and then you have to go back to the menu to see when the AirPods are ready for use. ToothFairy streamlines this: just click an icon in the menu bar (or press a hotkey) to switch to the AirPods, and the icon always shows whether they’re connected.

  • Works with AirPods, as well as any Bluetooth device that you can connect to your Mac: headphones, speakers, headsets, game pad controllers, keyboards, mice, etc. (HomePod is not supported, as it is not a Bluetooth audio device.)

Current Version: 2.7.3 (April 12, 2021)

Changes in Version 2.7.3
  • Fixed a regression where the “Global hotkey to connect/disconnect” button didn’t work with VoiceOver.
  • Added accessibility names and titles in the Preferences window.
  • Worked around an issue with macOS 11 that could cause Bluetooth to time out when connecting a device.
  • Improved the “Improve sound quality by disabling audio input from device” and “Why isn’t my device connecting?” sections of the manual.
  • Added the “How can I turn off Automatic Device Switching?” section of the manual.
  • Modernized code for Xcode 12.4.

Apple AirTag; Not Perfect, but Close to Being a Must Have for Anybody Who Is Blind or Low Vision and Uses an iPhone 11 or iPhone 12

By David Goodwin | April 30, 2021

After two years of rumour, speculation, and much hype, Apple's AirTag has finally arrived; and my early impressions and experience suggest that it might have been worth the wait if you are blind or low vision - most particularly so for those who use an iPhone 11 or iPhone 12.

For those unfamiliar, AirTag is Apple's new Bluetooth tracker announced at its recent “Spring Loaded” event. It's a button-shaped device intended to be attached to items that you might commonly misplace like keys; wallets; jackets; and backpacks, enabling their location to be tracked in the Find My app. Additionally, an AirTag can be set as lost, and any iPhone user who passes close to it will be alerted to its presence, and can optionally be sent a contact number and message that will help them reunite the lost AirTag with its owner. To further increase the likelihood of people being reunited with lost AirTags, anybody who doesn't have an iPhone but does have an NFC-capable phone is also able to identify a lost AirTag if they find it.

So far, AirTags might be sounding rather dull. One of those things you buy, hoping that you will never actually have to use.

But, before you tune out, let me introduce you to another of the AirTag's features, Precision Finding. This is where things get a little more interesting. Perhaps even quite exciting, for Precision Finding combines augmented reality, sound, and haptic feedback to guide users of iPhones with a U1 chip to the precise location of an AirTag. Oh, and did I mention that Apple has stated that AirTag includes support for the accessibility features built into iOS, such as VoiceOver?

Are you with me here in thinking of how Precision Finding could offer significant added value to somebody who is blind or has low vision?

Are you thinking of those occasions when you misplace something, and one or more of independence; pride; stubbornness; or nobody else being close by results in you spending minutes or more trying to locate your lost item?

Are you thinking of those times when you resort to asking a family member; housemate; friend; work colleague; or nearby stranger to be your eyes and find something for you?

Are you thinking about how nice it might be to instead simply grab your iPhone, and play a quick game of hot or cold - also known as Precision Finding in this case - to be guided towards the exact location of that misplaced item?

These thoughts and the relatively low price of US$29 for a single pack AirTag were enough to pique my interest and have me hit the pre-order button as soon as it became available.

What follows are my early impressions and experience with an AirTag. Read on to discover how despite the operational range of Precision Finding not being as far as I had anticipated and there being a few other disappointments, AirTags are still likely to be a useful addition to the toolbox of gadgets and apps that help to empower me.

CAPTCHA: Telling Computers and Humans Apart

By Paul Martz | April 28, 2021

Computer pioneer Alan Turing’s famous Turing Test quantified a machine’s ability to behave intelligently. In the test, a judge would communicate with a human and computer via a text-based communications medium. The computer would pass the test if the judge couldn’t’’ tell them apart. It sounds like something straight out of Blade Runner, in which Harrison Ford played a detective tracking down rogue androids posing as humans.

The Turing Test has real-world applications. The internet is rife with runaway automated processes, or robots, that continuously attempt to post spam to discussion boards, scrape email addresses, and perform other nefarious acts. If web admins had a way to tell whether a visitor were human or bot, they could eliminate a lot of spam.

CAPTCHA is an acronym: Completely Automated Public Turing test to tell Computers and Humans Apart. Traditionally, CAPTCHA displays an image containing numbers and text, which the user visually reads and enters into a text field. More modern versions ask users to select images based on some criteria, such as “select all images with ladders”. But computers have become pretty good at visual processing. Image-based CAPTCHA isn’t as effective as it once was.

CAPTCHA accessibility issues are obvious to the AppleVis community. Many vision impaired users depend on an audio-based challenge, in which users enter words spoken in a short audio clip. But this is not an option for anyone with a hearing impairment.

The Mac's Messages App Explained

By Tyler | April 19, 2021

If you have an iPhone, you’re probably fairly familiar with the Messages app on iOS, using it to send and receive texts, photos, videos, and other files. As part of Apple’s interconnected ecosystem, this capability is also available on macOS.

An example of how the Messages app could be useful on macOS is if you’re working on your Mac and a text comes in. Rather than stop what you’re doing and switch devices to view and respond to the message, you could simply open the Notification Center or Messages app on your Mac, view and respond to the message, and get back to your original task.

While certain aspects of the Messages app’s interface may initially seem confusing, there are a number of tricks, which I will cover in this guide, which you can use to maximize your efficiency with it. In fact, being able to do tasks like calling and texting seamlessly on both my Mac and my iPhone is one of my favorite cross-device integration features.
