How is the durability of Threema?
Customers' views on Threema's durability are mixed, with a clear trend toward declining satisfaction over time. While some users still report consistent performance and reliability, the majority express growing frustration with crashes, connectivity issues, and instability, particularly after recent updates. Positive feedback remains, especially from long-term users who appreciate the app’s stability in earlier years, but negative mentions have increased significantly, especially from late 2025 onward. The overall sentiment has shifted from confidence to concern, with a noticeable drop in ratings during 2025-12 and 2026-05, suggesting a deterioration in app reliability. Despite occasional improvements in later months, such as a brief rise in ratings in 2026-07, the balance of complaints outweighs praise, indicating durability is now a key pain point for many users.
What customers praise
Many users still praise Threema for its long-term stability and consistent performance, especially those who have used it for over a year. They highlight that the app has worked well without issues, particularly when compared to other messaging platforms. Some appreciate its reliability as a secure messaging tool, noting it remains functional and dependable under normal use. These positive experiences often come from users who have not encountered recent problems.
What customers said:
- „I would still like to see ephemeral messages“
- „Easy access to support from within the app and easy feedback (including new ideas)“
Common complaints
A growing number of users report frequent crashes and connectivity problems, especially after recent updates. Some say the app has become nearly unusable, with daily crashes and persistent connection failures. These issues are often described as a sharp decline from past performance, with users noting that the app worked reliably for years before recent changes. The frustration is heightened by the lack of clear fixes or communication from the developers.
What customers said:
- „since a few months almost unusable“
How it has changed over time
Durability concerns have intensified since late 2025, with ratings dropping from 3★ in early 2025 to 2★ in December 2025 and May 2026. The number of negative reviews spiked during these months, coinciding with reported update-related issues. However, there were brief improvements in July and August 2026, with ratings rising to 3.75★, suggesting possible fixes or temporary stability. Still, the overall pattern shows a decline in perceived durability over time.
What customers said:
- „really became so much worse over the years“
- „The one time fee is great.“
Practical takeaways
For users prioritizing long-term reliability, Threema’s current durability issues may be a dealbreaker, especially if they rely on consistent access. Those who value security and privacy should still consider it, but they should be prepared for potential instability. It’s advisable to monitor recent updates and user feedback before committing to long-term use. The app’s past performance suggests it can be stable, but recent trends indicate caution is warranted.
What customers said:
- „super unstable, call notifications delayed, connection interrupted often.“
