Suggest adding a custom modification to the keyboard to change the Enter key to the Send key

It is suggested to customize the keyboard to replace the enter key with a send key, so the input method can become transparent like liquid glass, as it does in the Apple Store.

Seit der Einführung der Desktop App gehen die Threema Web sessions nicht mehr zuverlässig. In der Threema App lassen sich auch keine WebSessions mehr scannen. Angeblich keine Kamera verfügbar. Das sehen alle anderen Apps anders. Bananensoftware

It was all good till I got "too many IDs created for this purchase..." error. Unfortunately now I can't create another ID and can't use the app. I can't renew or but another license either.

Espectacular

Acabo de comprarla y es espectacular. Hay que acostumbrarnos a proteger nuestros datos y Threema es ideal para eso.

A Trusted App Hands Down

I’ve been using this app for a few months now and it’s 100 times better than WhatsApp. I’ve had no issues. I’ve recommended it to other people and they love it. I feel connected and I feel like my messages are getting sent properly with no interruptions. Sometimes we have to try a few things until we get the “right” one and this so far is the right one!

fantastic app

this app is fantastic. It is well worth the one time charge that you have to pay to get it. It works flawlessly with voiceover however, when you go to generate an ID for the first time, you have to double tap and slide up to initiate that or use screen recognition or the touch area thing other than that, it works fantastically.
