In response to the question in the subject field ^{[no Tapatalk, an app, or a browser]}, there are a few stripped-down versions but only one of them is probably suitable for your case:

• Wap2 ^[responsive]: https://bitcointalk.org/index.php?;wap2
  
  • The remaining versions are:
    
    • Wap ^{[it doesn't come with the ability to create posts but it's responsive]}.
    • Imode ^{[it comes with the ability to create posts but it's not responsive]}

Note: Every single one of these versions has its own limitations and depending on how each post is formatted ^{[e.g. those with tables]}, viewing it using any of the above versions might be a nightmare.
