Best iPhone App to Save and Re-Read Twitter Threads
By Taha Baalla··5 min read
The best iPhone app for saving Twitter and X threads: ThreadReaderApp (web), Readwise Reader ($7.99/month), or Nemos (free, on-device).
The Core Problem
X (Twitter) threads disappear when accounts are deleted or suspended. Thread content is fragile by nature — you may want to revisit a thread months later and it is gone. Saving threads to a personal library protects valuable content.
ThreadReaderApp
ThreadReaderApp.com is the free web service: reply to any thread with @threadreaderapp and it sends you an "unroll" link with the full thread as a readable page. You can then save that page to any read-later app. Free. Simple. No iOS app required.
Readwise Reader
Readwise Reader imports X threads directly. Paste the thread URL, Readwise saves the full unrolled thread to your reading queue. Highlights sync to Readwise. $7.99/month or included with Readwise. Best for: avid readers who want thread highlights alongside other reading.
Nemos via Share Sheet
From the X app: long-press the share icon on any tweet in a thread, select Share, choose Nemos. This saves the tweet and its URL. For the full thread: use ThreadReaderApp to generate the unrolled page first, then save that page to Nemos.
Nemos extracts the full text of saved web pages, making threads searchable by any word. Threads are indexed alongside screenshots, PDFs, and voice memos. Free, on-device.
For Large Thread Libraries
If you save many threads per week, Readwise Reader is the most organized solution: threads, articles, newsletters, PDFs, and YouTube transcripts all in one reading inbox.
The Impermanence Problem
Twitter/X threads can be deleted. Accounts get suspended. Platform policy changes. Content you saved today may not be accessible tomorrow via the original URL.
On-device storage is the solution. Nemos captures save content locally. A thread screenshot captured to Nemos exists permanently on your device regardless of what happens to the original.
Practical workflow: screenshot each tweet in a thread (or use the iOS Share Sheet from third-party Twitter clients), capture to Nemos with a note about why the thread is valuable. For long threads: voice-record a 60-second summary of the key claims. The summary is often more useful than re-reading the screenshots later.
Organization: create a Smart Space for "Research threads" or organize by topic. Searchable by any word in the screenshots via OCR.
