Android Apps for Electronics and micro controllers ?

[Farmhand]

Until recently I've resisted the urge to buy a smartphone, but I have one now and I'm wondering if any Android users know of
any useful Apps for Android relating to electronics ect. eg. maybe an App for uploading programs to micro controllers and
electronics calculators and os on.

I found one App that I might install called "Electrical Calculations" which has a lot of various calculators.
https://play.google.com/store/apps/details?id=dynasty.electricalformulas.calculations&hl=en

I don't mind if I need to pay for a good App but free is better. Since I'm just new to Android and to Smart Phones/Tablets I
figured some others here may be able to advise me and others best.

Thanks.

P.S. I've got Android 4.2 on a Blackview-JK890-5.5 inch generic Smartphone, and plan on getting a 10 inch Nexus Tablet with
Android 4.4 on it, if that means anything regarding App choices I'm not sure yet.  Newbie. No Manual for the phone exists.

I could get a lot of use from this phone without even having a sim card in it or making actual phone calls.
My old phone can make calls.

That would suck bad.

There's only 2 choices IMO , microchip and pickit3.

Or LPCexpresso, ARM platform. Lpc link 2

Microchip easier to learn, lots of info in forums.

Lpc espresso better chips, superior platform.

Both free.

LPC4300 series makes my pants bigger, the things you can build with those is simply matrix.
These chips will replace fighter pilots in the future. Replace any PLC for 7 dollars.

Not sure what you're getting at, the micro controller program writing is one thing and can be done on a regular computer.
But the various Android Apps that may be useful for experimenters doing different experiments and calculations is another thing.

eg, "Axepad" is a lightweight program editor for picaxe, it can't do all the things that the "Picaxe Programming Editor" can do,
but it can be used for simple edits. One thing I'm wondering is if ie. a program can be uploaded to a picaxe chip from an Android
device, then there would be no need to take a laptop to the device or the device to a computer to upload an edited program to it.

Anyway It's handy not needing to turn on the computer to use a resonance calculator and so on, there's an App for that.
And someone suggested a light sensor, it seems my phone does have a light sensor so I'll try an App for a Lux meter that
can be calibrated, plenty of Apps for that.

Also Smart compass and magnetic sensors ect., not all phones have the required sensors for some Applications.

Still need a regular computer or laptop of course, but a phone or tablet is a lot more portable than a laptop and less expensive.

I got one for you Farmhand.   Very cool app.   I need to dig it out of my huge folder of apps but found it recently.   Description (it even has an Oscilloscope sim in it ) :
All joking aside, this time you will understand how electronic circuits work.

"I stumbled upon some serious gold" - GeekBeat.tv
"A fully realized circuit simulator" - EDA360 Insider

Build any circuit, tap play button, and watch dynamic voltage and current animations. This gives you insight into circuit operation like no equation does. While simulation is running, adjust circuit parameters with analog knob, and the circuit responds to your actions in real time. You can even generate an arbitrary input signal with your finger!

That's interactivity and innovation you can't find in best SPICE tools for PC like Multisim, LTspice, OrCad or PSpice (trademarks belong to their respective owners).

EveryCircuit is not just an eye candy. Under the hood it packs custom-built simulation engine optimized for interactive mobile use, serious numerical methods, and realistic device models. In short, Ohm's law, Kirchhoff's current and voltage laws, nonlinear semiconductor device equations, and all the good stuff is there.

Growing library of components gives you freedom to design any analog or digital circuit from a simple voltage divider to transistor-level masterpiece.

Schematic editor features automatic wire routing, and minimalistic user interface. No nonsense, less tapping, more productivity.

Simplicity, innovation, and power, combined with mobility, make EveryCircuit a must-have companion for high school science and physics students, electrical engineering college students, breadboard and printed circuit board (PCB) enthusiasts, and ham radio hobbyists.

Features:
+ Animations of voltage waveforms and current flows
+ Analog control knob adjusts circuit parameters
+ Automatic wire routing
+ Oscilloscope
+ Seamless DC and transient simulation
+ Single play/pause button controls simulation
+ Saving and loading of circuit schematic
+ Mobile simulation engine built from ground-up
+ Shake the phone to kick-start oscillators
+ Intuitive user interface
+ No Ads

Components:
+ Sources, signal generators
+ Resistors, capacitors, inductors
+ Switches, SPST, SPDT
+ Diodes, Zener diodes, light emitting diodes (LED)
+ MOS transistors (MOSFET)
+ Bipolar junction transistors (BJT)
+ Ideal operational amplifier (opamp)
+ Digital logic gates, AND, OR, NOT, NAND, NOR, XOR, XNOR

It's called Every Circuit v2.08.   I'll upload it to a fileshare service shortly so you can download it.   Since it is not being installed from the Play store just let me know if you aren't sure how to get it on your phone.   Here is the link to get it:

I had intended to start a message thread here to post this a week or so ago when I found it but got busy so I'm glad you reminded me about sharing it.   
PM sent.
