## What is Custom Running Intervals?

This is a flexible custom interval timer and training scheduler with historical analysis, and you are the only one who has access to your data! As a runner, I’ve had challenges finding a running timer that can manage my more involved interval combinations.  Custom Running Intervals allows you to build variable activities with repeatable blocks of intervals.  Intervals can be by time or by distance with 3 intensities - walk, steady, and fast.  You can repeat your intervals a specific or indefinite number of times, for a defined amount of time, or for a given distance.  With an inexpensive upgrade, you can create as many combinations of repeatable sets in the variations you choose, build a training plan on a calendar, see results of past runs, and export results to other apps.  Also, your data is only available to you - even I can’t see it.  Your data will only exist on your phone, or in your own iCloud storage if you choose.  If you save your data to iCloud (by default), you can view the results on any other iPhone or iPad that shares the same iCloud account.

Features:
1. Configurable intervals - distance (miles, kilometers), time (hours, minutes, seconds).
2. Configurable repeat blocks of intervals - # of times (or until stopped), distance, time.
3. Clone activities (use an existing activity - repeats and intervals - as a basis to create a similar activity).
4. Apple Watch monitoring and control and heart rate (iPhone app must be started).
5. Configurable settings.
6. Audio cues by voice, tone, or both (in Settings).
7. Pause, Resume, or Stop an activity, Skip repeat blocks.
8. View current elapsed time, distance, interval progress, overall pace.
9. End an in-progress repeat block (and proceed to the next).
10. Results by interval and repeat block, as well as default distance unit (each mile or kilometer).
11. Results (including steps, time, distance, and pace) available immediately after run.
12. Map view to verify GPS location prior to starting run.
13. Map view of running route in results including markers by mile/kilometer and pauses.
14. Helpful on-screen guide when creating first activity and configuring.
15. Activities and results stored in iCloud for synchronization across devices and data loss prevention.

Apple Watch
If you have an Apple Watch, you can also start, pause, and stop an activity in progress from the watch.  NOTE: the Apple Watch app (included with your iPhone download) communicates with the iPhone app, so the app must be started on both the watch and phone to use the watch app.

Apple Watch Features:
1. View existing activity configurations.
2. Start an activity (if iPhone app is started).
3. Pause, Resume, or Stop an activity.
4. View current elapsed time, distance, interval progress, overall pace.
5. End an in-progress repeat block (and proceed to the next).

Available Full Features (In App Purchase)
1. Configure an activity with multiple repeat blocks for more complex intervals (standard version allows one repeat block)
2. Add planned training runs on a Training Calendar for a selected custom interval (free version allows up to 5). 
3. View and filter a graph of your pace over time for activities (free version allows up to 5 past runs).
4. View the results of your runs on the Training Calendar including a map of the route. weather conditions, elevation, pace, and heart rate.
5. Create repeatable training plans to easily add planned runs to the Training Calendar.
6. Sort your past results by date, total time of run, distance, and pack.
7. Export your results (current or history) in GPX format for importing to other trackers.
8. Fix GPS for anomalies.
9. Import results in GPX format from any tracker app.
10. Track miles run on your pairs of shoes.
11. Manually enter results for a run if you forget to track.
12. Manually edit the time and distance for a run.

14. Track a run on a cruise ship.

### 1/5 — Does not work😖

*2024-12-07*

I just downloaded this app on my iPhone 14,I set up an interval then presses the SELECT button to commence the timer, and behold, this action exited the timer!
How about fixing this John!

### 2/5 — Good ideas but needs work

*2020-12-12*

The customization of intervals is awesome but there are a few issues that need to be fixed.

1. During an activity if you leave the current running activity there is no way to open it again. You are forced to begin a new activity, yet the first one is still running. 

2. It is unreliable as to whether or not the interval prompts will work when the screen is off. More times than not, when I closed my screen, the activity paused itself until I opened my screen.

3. When creating intervals the keyboard gets in the way so you can’t see what you are entering.

**Developer response:** Thank you for trying the app and for sharing your experience.  I personally use the app 3-4 times a week and haven’t seen the same behavior, but I’d like to better understand your issues.  If you have a few moments, I’d appreciate your visiting the support site and submitting a feedback form with additional information including your version of iOS, your iPhone model, and a few more details.  I realize that it might be asking a lot, but I would appreciate the opportunity to improve the experience for you and others.

### 2.6.1 — 2026-07-31

There were 3 bug fixes:
1. Cruise Runs - Pausing when running in cruise mode stopped distance updates which caused incorrect distance and pace in the results.
2. Results - Adding notes to a run incorrectly marked the run as 'Manually Edited' which is only intended to represent manual changes to time or distance.
