I would give it five stars if there was some kind of rhyme or reason why it does not consistently connect at right angles. I have used the right angle connections and there are times where it goes all over the place, when all I want is a simple left right connection. Other than that - it’s excellent!! Use for all my drawings now. Designer: Please add a boxed two-way boxed arrow to your symbology. Great price too!

This app seems to be only just slightly better than the “regular” ElectricDesign app, but still suffers from the same cruddy grid snapping issues. What the developer is failing to understand is that schematic layout should have TERMINALS on-grid, not shape boundary edges! It is impossible to get “clean” wire lines between components (simple connections without “jogs” in the lines) due to the horrible snapping and “kindergarten” routing. (You don’t accrue extra bonus points for the quantity of wire segments in your schematic!) Again, component terminals are not labeled. Again, there are bugs in the app (for example, unchecking “Keep proportions” does not allow you to resize a shape in one direction only). Incidentally, “Keep proportions” should default on, not off. Again, you cannot rotate shape labels. Again, there is no grid or alignment tools for creating new shapes. The shapes “library” has Ground symbols but no Vcc symbols. It would be very helpful with browsing if symbols were listed alphabetically. The new UI has a lot of cropped text. Even with a maximized window some of the toolbar commands are cropped and not readable. That’s really poor UI design. Zoom is VERY slow at high magnifications but behaves normally when viewing the full canvas. The zoom seems to work logarithmically rather than linear, which is very frustrating when zooming in and out from maximum magnification. Undo (command-z) resets your view (panning and zoom) and current selection, which is obnoxious. Exporting also changes your current view. Although this “pro” version overall has an improved UI and the ability to add connection points to custom shapes is a very welcome addition, the lack of practical grid-snapping and wire routing that is just plain irritating gives the app a very amateurish appearance.

There is a good selection of component templates and such. The available functionality, hot keys, &c are all reasonably complete. My main complaint is that the polylines (schematic wiring lines) almost invariably make really silly decisions about what path they should take, creating overly complicated routes with NC humps. The two most frustrating things about this are 1) even when I draw the line using a direct, clear path with no other traces in the way, it still defaults to some crazy beeline and 2) I end up spending MUCH more time fixing these lines than doing actual design work. This seems to make a nice sketchpad for laying out schematics (and so far I'm only doing analog design; perhaps it does better with logic circuits?) but there does not appear to be a way to actually analyse and export actual PCB layouts, Gerber files, &c.

I've used this app to layout a solar project. I find it pretty useful, but it's clunky at times. Snapping isn't consitent or logical, and having limited attachment points is silly when you want to keep lines at 0, 90, 180, 270 for clarity. Also if you want to add an object inline, you have to manually detach a line and create new connection points. Cumbersome. Also the objects don't scale well, and there aren't many useful ones (maybe this opens up when you pay). Also text labels are strange. You can't set a default size, spacing has heavy padding that you can't control, auto-rotate doesnt work. Again, if it were clear that these things would be fixed by paying, I would, but my trial test was just ok. I guess this is abandonware by now.
