Peergos has a mobile app.

what you give up by leaving Tresorit
- audited encryption, cross-platform clients, sharing policy, recovery, and compliance

why people still pay for Tresorit
People still pay for Tresorit because storage subscriptions sell confidence that files will still exist after a lost device, bad sync, or provider incident. The recurring cost buys chunking, encryption, conflict detection, versions, garbage collection, bandwidth, restore drills, monitoring, billing, and disaster recovery, not just the visible interface. If none of that applies to you, any pick above saves $167.88 a year.
