Must-have für Werkstatt, Ausbildung & Prüfung!

Endlich eine Werkstatt-App, die von Praktikern durchdacht wurde! Egal ob man schnell an der Maschine Schnittdaten, Gewinde und Passungen nachschlägt oder sich in der Ausbildung auf die Prüfung vorbereitet – Gesello liefert die exakten Werte ohne langes Suchen.

Besonders stark: Statt bloßer Zahlen gibt es schrittweise Rechenwege, anschauliche Skizzen und super Übungsmodi, die das Verständnis echt erleichtern. Alles funktioniert blitzschnell, offline und ohne Werbung. Die integrierten Tools in der Pro-Version sind jeden Cent wert. Absolute Empfehlung für Azubis, Facharbeiter und Meister!
