## What is Pace Ruler?

This simple tool utilizes GNSS (Global Navigation Satellite System) to survey distances on foot. The survey results, or tracking data, can be conveniently checked using an iOS map and are easily shareable via file sharing.

Settings:

- Remove Ads: This option removes ads via in-app purchase and displays a toolbar.
- Units: Choose between meter, international foot, or U.S. survey foot.
- Distance Calculation Methods: Options include iOS Default, Haversine, Hubeny (Simple Formula), Bowring, or Hubeny (Original). Bowring's method offers the best accuracy.
- Reference Ellipsoid: Choose between WGS84 or GRS80.
- GNSS Accuracy: Specify the allowed range of error.
- Automatic Shut Off: If there's no movement for about 5 minutes, surveying will stop automatically.
- Do Not Use Thumbnail: This option hides thumbnails.
- Use Light Mode for Maps: The map is displayed in light mode even if you are using dark mode.

Notice:

Continued use of GNSS running in the background can dramatically decrease battery life.

### 2/5 — Not accurate

*2024-07-11, version 2.7.3*

I tried this app and also compared it with a hand held measuring stick and it was off by 80 ft

### 1/5 — Wrong distances

*2024-06-18, version 2.7.3*

The distance is incorrect than what factual distance walked.   Do not use this app

### 2/5 — Not Wanting to Work

*2023-03-30, version 2.7.1*

I liked this app on an old work phone. I downloaded onto mine so I can see how much wire I will need. It’s not calculating anything of mine. I get the Initialize button and when I hit it and start walking it doesn’t work at all. I also get cancel but I’d like to use this app like I did. So maybe if that gets fixed I’ll leave a different review.

### 1/5 — Doesn’t work

*2022-11-17, version 2.6*

Just throws you in a feedback loop of doing nothing at all.

### 4/5 — Worked better than I expected

*2021-07-15, version 2.5.3*

I’m doing wind sprints on a desert trail and wanted to measure the distance I am sprinting each time. I used the app to measure in meters and it ranged between 121.5 and 122.2 meters. Seems to be consistent and accurate.

For shorter distances it varies wildly.

### 5/5 — Perfect for long distances

*2020-12-12, version 2.5.1*

I used it to measure a property that was about 467 feet long in the app and with a rough measurement using a tape measure. I was able to calculate the app was only off by 5-10 feet off which isn’t much in terms of long distances,

### 1/5 — Needs alot of work

*2015-03-08, version 2.1*

I was trying to figure out how far I was triple jumping earlier today... I noticed the measurements of jumps very close together were ranging from 32-40 ft.  This made me wonder how inaccurate this app was.

I went home and walked 12 paces.  I got a range of 7.6ft to 13ft.  This app needs alot of work before I'd use it to calculate any distances.... 

Back to the old fashion ruler😄

### 4/5 — Regla

*2013-06-27, version 1.1*

Muy buena, hay que ponerla en la ultima opción de "calculation method" para que ande bien. Gracias al creador.
