Droid Circuit Calc Pro Customer Insights

1. I only use my tablet on a stand in landscape mode.I also like to see sum more info on the circuits and more circuits eg power supply ,,,, boost regulator and theres a lot more 555 timer circuits on Google ....... update lolI would give it more stars but the images on the op calculator or any other calc are tiny.

2. Nice jobVery worst developer support 👎🏽... No responsevery helpful appVery nice appThis is a fantastic app with lots of good information and easy to use calculators for electronics.

3. Nice collection of stuff....but some of the schematics to accompany the calculators are MINISCULE and unreadable.

4. But doesn't say it has to be a PNP.Format for entry of values would not enlarge you could put in values, but not know where they belonged on the schematic that accompanied the calulatorCool little app.

5. It opens in landscape then rotates to portrait when a resource is opened.

6. Says 'any general purpose transistor will work '.

7. Shows dual transistor bi-stable led flasher.

8. Update; after all these years the developer still did not fix rotation of app.

9. Desperately in need of an overhaul i think hence 4stars.Lots of inaccurate statements.

10. Perfect beginners tool but still comes in handy for me as well.

11. Only works in portrait mode.
