Application très complète et diversifiée (électronique, mathématiques, programmation, dépannage...). Malheureusement, les achats intégrés dans l'application ne fonctionnent pas hors ligne ! J'ai payé mais je ne peux pas utiliser les 3 achats de l'analyse des nœuds et celui pour les circuits équivalents. Si vous êtes avec des cartes prépayées, ne faites pas d'achats intégrées, vous n'y aurez pas accès sans connexion car les cadenas resteront verrouillés.

Bem completo e muito útil pra quem quer aprender eletrônica ou quer ter acesso fácil a referências e informações para aquele projeto que está desenvolvendo. Especialmente útil para hobistas(como eu).

If you buy the additional PDF-Pack 1-4 for $2.80 (inapp purchase), you have to request the PDF by email, otherwise nothing happens. When you finally get the PDF (which is highly overpriced btw), there's an annoying watermark showing your email, across every single page, from left bottom to right top, in pretty big red letters. Never again‼️ App uninstalled, although I bought pro version 👎

Let me start with the bad things about this app...... I really cannot find any. Really well done and well worth the little it costs for pro version. I still have the non pro version on my phone too.
