Signal და WhatsApp

პლატფორმები

Signal მუშაობს iOS, Android, Windows, macOS, Linux-ზე. WhatsApp მუშაობს iOS, Android, Web, Windows, macOS-ზე. ეს იმაზე მეტ შედარებას წყვეტს, ვიდრე უნდა წყვეტდეს: სერვისი, რომელიც შესანიშნავია, მაგრამ თქვენს ხელში არსებულ მოწყობილობაზე მიუწვდომელია, საერთოდ არ არის არჩევანი. ასევე, desktop-კლიენტს იმაზე მეტი მნიშვნელობა აქვს, ვიდრე ერთი შეხედვით ჩანს, როცა ალტერნატივა ტელეფონის ყურთან ერთი საათით დაჭერაა.

• Available on mobile apps, WhatsApp Web, and desktop clients, with chats synced across devices.
• Uses phone numbers as identifiers, eliminating separate usernames.
• Offers free international messaging and calls over data without per‑minute charges from WhatsApp itself.
• Owned and operated by Meta Platforms, Inc.
• WhatsApp Business app adds business‑oriented messaging tools while using the same underlying calling and messaging infrastructure.

Signal

• Some users and organisations find phone‑number‑based registration limiting or privacy‑sensitive despite Signal’s design.
• Signal’s user base (roughly tens of millions of monthly users) is smaller than major messaging competitors, which can limit network effects.
• Certain governments have intermittently blocked or throttled Signal, causing connectivity problems in those regions.

WhatsApp

• Some reviewers express concerns about metadata and data sharing with parent company Meta, despite message content being end‑to‑end encrypted.
• Enterprise and privacy‑focused reviewers sometimes criticise limited multi‑device independence, as a phone number and device are still central to account setup for most users.
• Crowded chats and high message volume can make long‑term conversation management difficult according to user reviews on app‑analysis sites.
