October 16, 2019 - Recently, I had the chance to attend the Eclectic Tech Carnival (/ETC) in Athens, a feminist event about technology.

May 08, 2019 - In the last couple of weeks, location mattered deeply for Delta Chat, the “Chat over E-mail” messenger. It does make a difference if software development is situated in a Starbucks in San Francisco or around a refurbished coffee-bus in Kyiv, the Ukrainian capital just 200km away both from a war zone and from Chernobyl. Some of you noticed already the appearance of “on demand location streaming” in the advanced Android app settings. This unique feature was only silently released ahead of our “Xyiv” gathering which happened in the last week of April 2019. This post provides glimpses into what happened that week – with foreshadows of the coming Rustocalypse and evolving new takes on enmeshing UX, crypto and implementation activities in the wider decentralization space. Read on...

March 30, 2019 - Our first user-testing report is out.

The report highlights seven key findings and references some of the work that already happened since the testing happened. Read on...

March 14, 2019 - A new major Delta Chat Android release (0.200) is now on Google Play and soon on F-droid with lots of improvements addressing popular complaints and feature requests.

Please continue or consider helping us to evolve Delta Chat by providing feedback, contributing improvements or a little donation. If you join our channels you’ll also get to hear many of the upcoming good news earlier than here ;) Read on...

January 27, 2019 - A lot of efforts in the last half year are coming to fruition … release time! You can now use DeltaChat not only on Android but also on Desktop and iOS and chats are usually synchronized quickly in common multi-device settings. Nothing ever quite works perfect but it’s working well for many who used the incremental releases the last weeks, including for lots of private communications with friends. We consider our January 2019 releases, even if a significant milestone, only another beginning for more fun and interesting things to evolve … Read on...

December 19, 2018 - Our Ukraine/needfinding report is now out. It contains ten findings and “Delta.Chat takeaways”.

November 17, 2018 - More than a dozen people gathered for a week in Kyiv, Ukraine for “Delta-XI”, with more things happening than can be reported… This post is a try to both give you some picturesque glimpses of the gathering and also highlight technical developments and results from the rich discussion and collaboration originating in Kyiv at the end of October/beginning November 2018. The gathering was intentionally intertwined with two user-testing sessions which Xenia and Vadym professionally conducted with select groups of journalists, trainers and activists early in the gathering week. There were also many other significant results which we’ll only briefly report up front here: Read on...
