Threema gets better with every update. This time, the improvements mainly concern design and usability, but some new functionality has been added, too.
With version 2.5 for Android, users can choose between a light and a dark theme (to switch, go to settings / appearance). The new dark theme not only looks sleek and elegant, it also helps preserving battery life on devices with AMOLED displays.
Other additions and improvements include: storage management for messages, media and files; multi-select, multi-delete and multi-forward messages in chat; advanced image editing before sending (crop, rotate); and a new location chooser.
