Terraguard
A capable developer can build a functional replacement of the core photo-triage, logging, reminders, and PDF export in about a week, but matching the app's breadth, tuned AI triage quality across many species, and App Store polish is harder and would take more effort.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User snaps photo → image is analyzed with species/context → triage result stored on pet timeline → reminders and care logs updated → vet-prep PDF export
What it still won’t have
- App Store distribution, reviews, and existing user base
- Tuned AI triage behavior and any proprietary training or curation not provided by generic models
- Polished iOS UX, widgets, and lock-screen integrations
- Anonymous Apple-account subscription handling and in-app purchase plumbing
What remains hard
- Execution quality
We also improved overall performance, reliability, and the interface.
First-year cost
No published price
Terraguard does not publish a price we could read, so there is nothing to compare against. What building costs is below.

Runnable build prompt
Build a minimal TerraGuard-like iOS app with a Node.js + Express backend, Postgres for structured data, S3-compatible object storage for photos, and a hosted vision API (eg. OpenAI/Replicate) for image triage. Core features in scope: iOS photo capture and upload, per-animal species-aware profiles, UI for photo timeline and simple logs (feeding, weight, shedding), send photo+context to a vision model and render a 4-level triage result, recurring reminders with local push notifications, and one-button PDF export of last 30 days (weight chart, feeding log, photo timeline). Out of scope: training custom models, multi-tenant billing/Apple IAP server-side reconciliation, App Store submission polish, and advanced husbandry calculators. Include error handling for failed uploads and model calls, background retry for uploads, unit tests for backend endpoints, and end-to-end UI tests for core flows.
How we checked
How the score was reached
- Partly verdict base52
- 3/3 assessment runs agreed+4
- Evidence score56
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
