Pros and cons of eTools PRO app for iPhone and iPad

eTools PRO app good for

All the functionalities Ive tried are working great and the application is really useful

This App is very very large. There is everything you need. Unfortunately it is not listed in the description, but on the website. The app works very reliable and doesnt crash at any time. best electronic app in the store !!!

This seems to me to be the perfect all in one app. The pinouts have beautiful pictures and very informative text descriptions. The color code search functions for the various electronic parts are easy to use. I have not used all the features such as the calculators extensively yet but the price is worth it just for the pinout features alone. I think it deserves 5 stars.

This app has a lot of work put in to it. There is still room for perfection , but it is the best Ive seen yet. Nice job ;)

This App is a great reference for all like me that forgot most of this over the years. The interface is well designed and easy to navigate and use.

I use it everytime I work on my electronics project, the capacitor section is great when you try to find out which value it is!

Some bad moments

This application must have 7400 family ics datasheet and pin connection. Exactly very poor application.

Regulator 78xx TO92 reported inverted pin out !!! Is inverted from TO 220 check this and your contact form in your site not working.

I used this app once and it worked great. The second time (a day later) it crashed my phone when I tried to open it. Every time after that its has not worked. What a piece of crap. To bad I cant get my money back.

Every page of this app is well thought out with its design. The calculators make it easy to enter the information with diagrams showing the calculation. There are pinout diagrams of just about every connector you will run into today. The reference sections tie a lot of different information into a concise one-stop-shop for just about anything electrical or electronic. What prompted this review? The developers quick, polite response to a feature request and it being there in the next release.

Use it often as a computer tech. Great tool and a must have IMO.

I use this app daily and would strongly recommend it to everybody, there is somthing for everyone!!!!!!
