Scientific Calculator is an Android app that features a comprehensive scientific calculator for students and those that work in physics or something similar. It is developed using data from the National Institute of Standards and Technology and includes compatibility with NIST SRD 122 and NIST SRD 144 standards. It also features lots of different Fundamental Physics Constants that are easily browsed from within the app and insert into your equations to quickly work things out without needing to jump through so many hoops. With an Android Wear app to boot there’s little that Scientific Calculator doesn’t do, and it’s a free app for those that need a dedicated calculator no matter where they are.
To get started with the app is nice and easy, all you need to do is download Scientific Calculator from the Play Store, and you’re good to go.
There’s no instruction with Scientific Calculator, but everything is fairly easy to follow, the only thing that takes some getting used to really is the shift button and that’s about it, you tap in equations, and you’re given answers in return, it’s as simple as that.
Users are given a History to look through, but it’s not all that helpful, I have to say. There’s no record of the equations that led to these answers, just the answers themselves.
Tapping on these entries won’t bring back the equation in the calculator view either, it’ll just put the number in the LCD display once again.
Having said that, the calculator makes up for this with the inclusion of hundreds of different constants, all of which are easily searched through as well.
Now of course, there’s a little more to Scientific Calculator than just this, as there’s also an Android Wear element to things as well, which is great for those that might already have dedicated hardware for those sort of thing.
Scientific Calculator is a simple and useful application that has everything you want from an app like this. Regardless of whether or not you’re using it for professional or personal use, Scientific Calculator can be a big help. Thanks to the big list of constants, which users can even get up on their wrist, perfect for writing out notes and workings as well as the NIST standards this is a Scientific Calculator that people can trust. While there is a single ad banner at the top of the app, it doesn’t get in the way of overall operation one bit, and it keeps the app completely free. Serious students or those in the profession will probably keep hold of their dedicated scientific calculator, but this is great for those times when it’s buried in a bag or left in the office. Besides, being able to look up constants on your wrist is great as it gives you one more screen to work with when tackling long equations.
- Speed (4/5) – Scientific Calculator works great and there are no slowdowns when doing long equations, either.
- Theme (4/5) – The classic look and feel here works well and the overall interface is fun, especially the faux-LCD display.
- Features (4/5) – This ticks a lot of boxes, not least the NIST standards and the massive list of constants that users can look up on their wrists as well as the phone.
- Overall (4/5) – For a free app that offers up industry standard calculations and constants, this is well worth having. The Android Wear component is compelling as well, and can be a real help at times, too.
- Works for NIST SRD 122 and NIST SRD 144 standards which will please many professionals and students.
- Many of the needed constants are all included, for free, within this app and they’re accessible from your watch as well.
- Retro look and feel makes this as easy to use as any other calculator out there.
- Unlimited history of answers to work with.
- Voice search for constants on the phone would be nice as well as the watch.
- History doesn’t offer anything more than the answer, no working or equations.
All-in-all, for a free scientific calculator, this offers up a whole lot. It’s easy to use and there’s little that gets in the way of getting work done. It feels and behaves as any calculator would, and the included NIST SRD 122 and NIST SRD 144 standards and constants are a nice touch. It would be nice if the history displayed more than just the answers, but there’s always room for improvement.
