Go figure – ClassPad.net is a web based graphing calculator.

NEWS – Back in 2003, Casio released a stylus-based graphing calculator that featured a computer algebra system. It was a hybrid of the typical number pad calculator of the time and a PDA. The most recent version, the Casio fx-CG500, was introduced in 2017.  Casio has also made a web version on the website Classpad.net. This website is in beta-testing and includes a calculator, analytical geometry, graphing calculator, statistical operations, and commentary. The user interface is composed of boxes that contain calculations to be performed, statements to be graphed, geometries to be studied or values to be statistically analyzed. Related boxes are connected by spline curves as is typical of visual programming.

The greatest benefit of the software is its cross-platform capability and the ability for teachers and students to share problems and solutions with each other. The software still has some problems to work out as evidenced by the screenshot below. While “i” is on the entry keyboard, neither sqrt(-1) = i nor i^2=-1 is calculated. Also solve(7*x^5-3*x^4+2*x^2-25,x) only yields the one real root 1.34925, and doesn’t provide the 4 other imaginary ones. Also, adding or subtracting very large numbers does not provide the correct result, even when using the computer algebra system. The limit to the right on the screen shot below approaches zero as x becomes infinite.

One thing that I found perplexing is that there is no way to save the screen to pdf from within the program and no way to copy the algebraic forms from the paper. At least the statistical tables allow cut and paste from and to Excel, but not the statistical result.

While in beta the use of all of the site features is free, although at the end of beta handwriting recognition and the computer algebra system functionality may need to be purchased.

If you’re searching for a powerful cross-platform calculator or looking for a tool to teach math in a computer-rich academic environment, then the Casio ClassPad may be what you’re looking for. For more information visit ClassPad.net

Newton Mail review

If you’ve been reading The Gadgeteer for any length of time, you know how I like to drone on and on about how I can’t use a tablet or smartphone as my only “computer” when I travel because of one main reason. That reason is Gmail. I use Gmail as my email client of choice and I consider myself as a power user. On my laptop, I can use multiple inboxes, canned replies, all the stars, and 100’s of labels to organize and keep track of things that I need to get done using the web version of the Gmail app.

The problem is that I can’t completely unplug from tech when I travel because my inbox would quickly become a disaster within a day due to the number of emails that I receive. Yes, I know that there is a perfectly fine mobile Gmail app. I’ve used it for years. But for some insane reason, Google doesn’t provide the mobile version of the Gmail client with the same power user features as the desktop version of the app. With the mobile Gmail client, I can’t create multiple inboxes by using a dozen different colored stars, I can’t use canned replies, and worst of all, I can’t easily search for messages with certain labels or file emails with existing labels or create new labels. So I end up taking my laptop with me whenever I travel which means that I easily get sucked into wanting to work when I am supposed to be relaxing. Or at least I did that in the past. I’ve recently come one step closer to being able to leave my laptop home since discovering Newton Mail.

What’s Newton Mail?

Newton Mail is an email client for iOS, Android, Windows, and macOS that you can use with different mail services like Yahoo, iCloud, Hotmail, Outlook, and others including Gmail.

Features and usability


Newton Mail has all the features you’d assume an email client should have like the ability send and receive emails. Duh. But it has other features that make it the perfect email client for me and my obsessive compulsive email filing disorder. Yes, that’s a thing… or it should be a thing.



Newton allows you to tag an email to a label without having to scroll through a list of 1000’s of labels just to get to the one you need. Instead, you can start typing the label’s name to narrow down the list. AND, you can create new labels. It sounds so trivial, but this is the first mobile Gmail client that I’ve found that allows you to do this and that’s why I’m so happy to have found it! Being able to type in the label name without having to manually find it saves me a LOT of time.


In addition to that very important feature, Newton Mail includes other great features that you I haven’t found with other email apps. One of those features includes the ability to snooze a message. When you snooze a message, it will disappear from your inbox and reappear later at the time, date, or on the platform that you specify. I’ll admit that this isn’t a feature I use because I like to take care of things as they appear. But I do see it as a useful feature that I may add to my workflow at some point.


Newton will also allow you to save messages to your favorite productivity apps like Evernote, Todoist, and more.



Calendar access is integrated into Newton Mail too, which means that you can easily pull up your calendar without leaving the app, and you can even create events from within an individual email.


I also like that the app suggests people to send an email to when you compose a new one. If you click the little blue clock icon, you can toggle read receipts, reminders if the person doesn’t get back to you in a specified time, or you can schedule the email to be sent later.


I really like the read receipts so you’ll know when someone has read your email after you’ve sent it to them. You can toggle the read receipts to happen for all emails or on an individual basis if you don’t want to be bothered with too many notifications.


Speaking of notifications, you can even customize how those are handled when you swipe them in the inbox. There are 4 types of swipes for each message and each one can have its own action. Cool right?

All of these features help me achieve email nirvana, which for me means inbox zero or for those who haven’t heard that term, it just means that my inbox is empty and all the messages are stored where they should be.

I’ve been using Newton Mail for the past month and love it. They recently introduced a new feature that they call conversation view which they say gets rid of the sent folder because all the emails to the same person are grouped together including the message that you sent to start the email thread. This keeps you from having to go into the sent folder to look for messages.

I tried this new feature for a few days and didn’t care for it so I turned it off because it made my inbox more cluttered than I liked. I can see the advantages of having your original email in the same place as the responses, but that’s not a priority feature that I care about.

But all this yummy email goodness comes at a price

I’m not a penny pincher, but I don’t like paying for a 100 different subscription services. That’s why I ditched Nest security cameras in favor of WyzeCams and it’s why do regular audits on services I pay for but don’t use enough to justify the monthly or yearly subscription price. Some examples include Hulu. I dumped it when I started using Chromecast from my phone to watch shows on my 65-inch TV and it wouldn’t cast the audio along with the picture. So it went bye bye. I also dumped Evernote when I realized that I was paying $50 per year for a service I was rarely using.

So would I pay $50 per year for Newton Mail just for a handful of features that are missing from the free Gmail app from Google? While I wish the price was less than it is, I think that Newton Mail is completely worth it for me just for the time I save dealing with email when I’m mobile.

What I like

I like Newton Mail because it’s similar to the Gmail app that I know and love but on steroids. The easy label lookup, filing, and the creation of new labels is my absolute favorite feature, but the read receipts is a close second. Add in the ability to snooze emails and send them later and all the other little extras and Newton Mail has swiftly become my favorite email app.

What needs to be improved

While I really enjoy Newton Mail, it isn’t perfect. There are a few features I wish it had to make it even better. Canned responses and multiple stars like the Gmail web app would be awesome as well as Gmail’s reply prompts. Those features would just be icing on the cake though.

Final thoughts

If you consider yourself a Gmail power user and have been let down by Google’s stock Gmail mobile app, you should definitely try Newton Mail. I think you’ll be impressed. Give it a try, you won’t be disappointed. You can test it for 14 days for free.

Price: $49.99 a year (14-day free trial)
Where to buy: Newton

Nebo by MyScript makes my iPad feel like my long-lost Newton

I’ve written quite a few articles for various publications in the last 30 years or so. All of them were typed on some sort of keyboard, until this one. I am writing this on my iPad Pro 12.9″ with an Apple Pencil using a software app called Nebo from a company called MyScript.

Twenty years ago, I had a Newton from Apple. It was larger than the iPhone 8 plus I carry now, but the handwriting recognition was quite good. Sure, the first generation text translation made a lot of goofs, but with the second generation, they learned not to only translate from a dictionary. This reduced the incidence of “Egg Freckles” translations to a statical zero.

Now that I have a replacement for that technology, I am eager to see Apple add pencil support to the iPhone! I think as an option, pencil enhanced text input would catapult the handwriting desires of a few into high gear.

Those using digital ink technology today still are hampered with two things: transcribing the ink to an editable format, and then making sure what is deciphered actually is what the original writer meant. You’ll notice above the hand-written text in the screenshots, the text is being translated and spell-checked in real time. This allows the writer to pause and be sure of the spelling, intent, and word choice. Or, after full conversion to text, to edit traditionally with a keyboard.

This section is added using my Mac keyboard as I’m posting the screenshots and text pulled in from Nebo:

The Nebo software is available for $5.99 on the Windows 10 Store, GooglePlay store, as well as the Apple AppStore for iOS. Check the stylus requirements. I know the iOS version requires Apple Pencil, the other two have similar limits. If you have the hardware, though, this thing is a treat!

Exist app knows if tweets, emails or working out makes you happier

Is there an app that can figure out what makes you happy, productive, and active? Hello Code’s Exist for iOS and Android thinks it can. This app gathers data from your Twitter account, email account, local weather, Google Fit, Withings, Fitbit, Instagram, Facebook, and other accounts to draw conclusions about your moods and behaviors.

The app gives you the ability to add any tag that you’d like to your day like sick, headache, vacation, travel, etc. and will then use these tags with the rest of your correlated data to show you trends for your behavior and activities. Some trends might be that you’re more active on Mondays, or that you say you’re happier on days when you don’t receive as many emails, or that you’re sad on days when you send more tweets.

You can also use the app to track habits like flossing, working out, etc and receive a weekly email showing an overview of everything that happened.

The Exist app is free, but the service costs US$6/month with a free 30-day trial so you can get an idea of what types of info it can tell you about yourself before you actually start paying for it.

These days, we all use so many different services, that it’s interesting to see how the data fits together to form the puzzle of your days and weeks.

Grab the free Exist app at Google Play store or iTunes and visit exist.io for more info.

Keeping my balance in check with Dollarbird

I’ve been using a checkbook application on mobile devices ever since my first Palm Pilot. It was a simple application, probably cost me a dollar to download and didn’t come with many bells and whistles (and God forbid your battery died before syncing your Palm) but not having to bother with a handwritten checkbook register anymore was a revelation.

Since then, I’ve tried out dozens of finance trackers on my iPhone and the only one that stuck with me was Dollarbird.

What really sold me on their app was the lovely color scheme, simple interface and month view. I haven’t found a more useful display of where my money has gone and how much of it I’ll have left by the end of the month.

This month view has saved my butt so many times.

For instance, if I have a recurring daycare check set up every week and monthly bills, like a car payment, set to come out on the same calendar day, those payments are reflected in the balance at the end of the month, or on whichever day you tap on. I’ll always know how much money I have left to spend in the month after budgeting and setting up bills and transfers.

There’s even a great overview screen that tells you what you spend in each color-coded category every month and if you’re on track to spend that much compared to previous months.

It’s not the most robust budgeting tool, but it works for me and has kept my spending in line for years, now.

In Dollarbird’s recent upgrade, it moved to a subscription-based model in a shift toward catering to partners, families and teams. This isn’t an uncommon move with mobile apps… Ulysses, one of my favorite text editors for both Mac and iOS, just made the jump from flat cost to recurring fees and caught a fair amount of flack for it.

But in this instance, Dollarbird retained a free single-user subscription, which is perfect, because I’m the only one who uses it in my family. It also expanded accounts into a web interface, so you can check your balances from any connected device and also rest assured that your records are backed up online.

Dollarbird is available free on the App Store and Google Play and I really think it’s work checking out if you’re looking for a good budgeting and checkbook application.
