Bug fixes for the iPad layout, push notifications, analysis charts and the widget. Data sync after app updates is more robust.

### 4.2.1 — 2026-09-01

Bug fix: long-standing installs could gradually show too few assemblies. The data sync has been reworked from the ground up – affected installations repair themselves automatically with this update.

- New: a chart where you enter your own keyword and see how often that topic was registered in the seven weeks before the 2021, 2023 and 2026 elections.
- New: a breakdown of the most frequent topics and the parties named during a campaign, with an explanation of how the numbers are put together.
- The updates page now points out that you can be notified about newly registered assemblies.
- Plus smaller fixes to the layout and the translations.

- A partir de agora, descarregá-la de novo custa um valor único. Quem já a tem mantém-na gratuita para sempre.
- Novo: uma página especial sobre as eleições de Berlim de 20 de setembro, com todas as manifestações à volta da votação.
- Além disso, pequenas melhorias no arranque e na apresentação.
