Reliable iPhone SMS export tool
Problem
People need to export iPhone text message histories (for legal disputes, archives, or switching phones) and there is no solidly reliable, secure consumer tool for it. Existing options are sketchy desktop utilities or paid services that mishandle attachments and threads. A Reddit user explicitly begged developers to build one and charge money for it.
Opportunity
A privacy-first, one-time-purchase app (local processing, no cloud upload) that exports full iMessage/SMS threads with attachments into clean PDF/CSV formats for legal and archival use.
Market analysis
The pain is real and legal-grade demand is well documented, but the premise that no reliable tool exists is outdated: iMazing, Decipher TextMessage and TextPort all produce timestamped, locally-processed PDF/CSV exports today.
Market · Consumers and lawyers needing court-ready message evidence (custody, harassment, small claims), plus archivers and phone switchers; family-law use cases appear repeatedly in vendor positioning.
Pricing · One-time purchase is the norm: iMazing sells perpetual licenses in roughly the $30-50 range, Decipher TextMessage sits below that, and TextPort is a freemium phone-first app with paid export.
Pros
- + High-stakes, recurring need with a documented 'please charge me for this' audience.
- + Local-processing positioning matches the privacy sensitivity of legal evidence.
- + Clear output spec: timestamped, paginated PDF and CSV is a well-understood deliverable.
Cons
- − Established incumbents already do local, backup-based export credibly (iMazing, Decipher TextMessage).
- − iOS sandboxing makes full-history export from an on-device app fragile; desktop backup parsing is the proven route and adds a desktop build.
- − Attachments, reactions and thread integrity are exactly where existing tools fail, and they are the hardest engineering part.

The differentiator cannot be “exports SMS to PDF” because that ship has sailed; it has to be evidence-grade fidelity where incumbents quietly fail: attachments that stay bound to the right message, reactions and edits rendered sensibly, and a chain of custody (hashing, signed PDFs) that holds up when opposing counsel challenges the printout. iMazing already sells signed PDFs on business subscriptions, which tells you the legal segment pays premium prices for exactly that assurance. A solo builder without a desktop app should be skeptical of the phone-only route: screen-capture approaches degrade with very long threads, so the honest version of this product is a small Mac utility that reads the local backup, not an iPhone app.
