What we measured on a device
This audit is a desk review of store listings, privacy labels, developer pages and independent articles; no app was installed or measured on a device for this report.
How we decided
Each app was scored 0 to 5 on eight criteria: core task fit (Q1, 0.20), accuracy and reliability (Q2, 0.15), offline use and no account (Q3, 0.15), privacy (Q4, 0.15), ads and price (Q5, 0.10), accessibility and localisation (Q6, 0.05), maintenance (Q7, 0.10) and risks (Q8, 0.10). The weighted total is the sum of score times weight. If the top two totals differ by 0.3 points or less, the result is a tie; no tie is broken by opinion. Every score cites a source read on 2026-11-05; unverifiable claims are marked unverified and scored 0 or 1. This was a desk review of store listings, not a device test.
The person we evaluated for: hikers who need a compass with no signal. What they need to get done: read a bearing within 2 degrees without network; works in airplane mode; calibrate with figure-eight.
| ID | Criterion | What is checked | Weight |
|---|---|---|---|
| Q1 | Core task fit | How completely and directly does the app do the persona's main task? | 0.20 |
| Q2 | Accuracy and reliability | Is the output correct and stable? Evidence, not impressions. | 0.15 |
| Q3 | Offline use and no account | Does the core task work without network and without creating an account? | 0.15 |
| Q4 | Privacy | Data collection, trackers, permissions, App Store privacy label / Google Play Data safety. | 0.15 |
| Q5 | Ads and price | Advertising, price, in-app purchases including hidden or recurring ones. | 0.10 |
| Q6 | Accessibility and localisation | Accessibility support and number of supported languages. | 0.05 |
| Q7 | Maintenance | Date of last update, supported OS versions, developer responsiveness. | 0.10 |
| Q8 | Risks | Security issues, deceptive practices, unexplained permissions. | 0.10 |

- The price, star rating, required Android version and languages of NorthPin on Google Play were not shown.

This is a desk review of store listings read on 2026-11-05 using the US storefronts; no app was installed or measured on a device, so no bearing accuracy was tested. Privacy labels and Data safety sections are developer declarations. Store pages were read through a text extraction tool, so most quotes are marked as paraphrases. Apps were chosen from search results and one independent article, not from a complete survey. Ratings, prices and updates can change at any time.
