What is Squematic capture?

You joking, huh?
Try "schematic" there.

FWIW it is "Esquema" in Spanish (hint: Osvaldo´s native language) ... ring a bell?

I often see similar User Language slipping into questions from French, German, Dutch, Portuguese, etc. Forum Members and nobody gets his panties rolled up in a wad.

Back to the OP question: I once loaded PCB design software in a Tablet, as a "backup" or use when traveling; if anything to "do something" in long distance Bus or Plane travels.

It worked reasonably well (although it´s weird doing such stuff on a finger sensitive screen) but after a couple times I discarded it, found it much better to plain design with pencil and paper (while traveling that is) and transferring/copying it on proper software running on a Notebook or desk computer when reaching destination.

Use it as your only available design system?
I guess you will smash it against a wall after some time 😉

Don´t ask 🙁

May be wrong, but just thinking aloud: "any" drawing software can draw a schematic, also the PCB, but as a purely "graphical" job, nothing further, no interconnection at all..

In the early days many used AutoCad for that, and of course results *look*excellent; there were add-ons which incorporated symbols,shapes, footprints, you-name-it

Necessity is the Mother of Invention: a very clever guy, Sargent Harry Lythall SM0VPO was a RAF Radar end Electronics Warfare Technician stationed in a secluded Air Base in Saudi Arabia.
He is quite the DIYer, but it was absolutely forbidden to install any software at the Base computers for obvious Security reasons, so he created a way to draw very usable PCBs (he experiments mostly on RF) ... on early versions of Windows Paint !!!

On the other side, Schematic capture programs allow you to draw a nice looking schematic, but also Capture real components (not only "shapes"), linked to real world parts, their footprints and their connections, way more useful and important.

And that can help immensely to draw PCBs, which in general is the end result.

Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor.

My apologies for the typo. I didn't see it.

I normally use the most elemental text editor for schematics: the edit.com. It is quite simple and low size files.
Also I use ORCAD SDTIII for DOS. Or Express PCB on XP. A guy from the autotrax program gifted me the last version for DOS, the ATX v. 4.0. But l am now seeking for a program or app for Andoid.

Thanks for all for suggestiond, particularly to JM.

The edit.com as "schematic capture": simple and easy. And free to add text and formulae (using CP437 and MODE 80,50 DOS command for better view) in pure DOS AMD486 PC.

My Android tablet works nicely with a Bluetooth or USB (OTG) mouse, but I only used the rodents when the touchscreen was acting up. Screen resolution is far better than computers I've used for CAD in the past.
It may be possible to run old CAD programs using an emulator.
