Formatting on Android, honestly ranked:

  1. Overleaf (web app): the real answer. Full LaTeX in Chrome, compiles in the cloud, works fine on Android tablets.
  2. Google Docs: fine for non-LaTeX venues, terrible for equations.
  3. Authorea: collaborative writing with LaTeX support.
  4. TeX Writer: offline LaTeX editing for Android.
  5. VerbTeX: LaTeX editor with cloud compile.

The truth: nobody formats a real paper start to finish on a phone. Android is for reviewing PDFs, approving co-author edits, and checking compile errors from the conference hotel.

Test-compile the template on a tablet before traveling; hotel wifi and deadlines are a brutal combination.

Email yourself the CFP link too; screenshots are useless when you need the submission portal URL. Sources: IEEE, ACM Keep the venue's official template in Overleaf from day one. Template violations cause desk rejections at NeurIPS and CVPR, and no app fixes a wrong template after submission. VenueFit includes formatting checklists per venue, free.
