User reviews

Tut was es soll …

(1) Version 6.5.1 (404) [auf MacBook Pro M4 Sequoia] läuft sehr gut und stabil.
(2) Das Interface ist etwas gewöhnungsbedürftig aber funktioniert.
(3) Verbindung zum TXT 4.0 Controller tut auch, wenn man weiss wie … Hinweis : Bedienungsanleitung(en) in der Dokumentation hinterlegen (als pdf oder eventuell auch nur einen Link oder Hinweis)
(4) Ich habe bislang keine Doku zu den TXT Fischertechnik Bibliotheken gefunden, eine einfache Beschreibung der offiziellen Funktionen tät’s schon. So wie beim RX.
(5) Man ist doch stark eingeschränkt (z.B. immer nur ein Projekt offen) und kann hier nichts mit anderen Systemen verbinden, aber es soll ja auch eine Lernumgebung sein (für Maker dann doch eher Arduino).
(6) Blockly und die Inkonsistenzen mit Python sind ein anderes Thema …

Das ganze ist alles in allem recht gut und man kann die Probleme mit etwas Mühe selbst angehen (Doku eben selbst suchen / Beispiel durch sehen), vor allem es tut! Aber vorallem inhaltlich noch Luft nach oben.

UX nightmare

To me this is a typical German engineering product: technically really good, but it looks very old-fashioned and isn't fun to use. When developing the UI, they clearly didn't think about the user and the platform they’re developing for. That’s especially sad as the product is actually aimed at children and young people and this generation knows what modern interfaces are usually like.

Honestly, I've rarely been so frustrated by an app. The software isn't much fun on a PC, and then to simply recompile it for mobile/touchscreens and hope for the best and that users will somehow manage to get along with it is really tough. And by the way, this Fischertechnik stuff isn't even cheap.

Selbst als erfahrener Ingenieur und SW-Entwickler hangle ich mich von Bug zu Bug!

SW-Stabilität? Leider bei FT offenbar ein Femdwort. Die Verbindung zw. Mac oder iPad zum TXT 4.0 ist sowohl per WLAN als auch per USB reine Glücksache. Die Schnittstellen-Übersicht hängt öfter, als dass sie funktioniert (Eingang Fototransistor geht überhaupt nicht).
Schade - denn mein Sohn und ich sind absolute FT-Fans. Nur der TXT 4.0 samt RoboPro Coding gehört nicht dazu!

Bug fixes needed

I found following bugs:
1. block comment does only accept one single letter
2. exported project to local can’t be imported. Greyed out not selectable
3. entering debug mode only works once. Need to restart app
4. debug mode: how to create breakpoint?
