when Supabird is actually the better choice
Supabird has a well-designed X-native mobile experience — if you primarily manage your X presence from your phone and want a lightweight app optimized for that workflow rather than a full web dashboard, Supabird's mobile UX is more polished for X-only mobile creators.
