iPhone app recording issues

We've seen a recent increase in the number of iOS users reporting GPS issues when recording but we aren't quite sure of the cause. This means the app freezes or stops mid-recording which results in incomplete data and missing portions of your activity. To help us investigate the issue, please try the troubleshooting steps below and let us know if it improves your future recordings:

  • Try turning your phone completely off then on.
  • Try turning location services off then on. Location services are located in settings > privacy > location services (turn off/on).
  • Try turning off wifi before and during recording. 
  • Close all other open applications before recording and if you open another app during your activity, navigate back to Strava afterward.
  • Lastly, sometimes recording data quality can be improved by giving your phone more time to acquire satellites prior to starting your activity. Try opening Strava when you have a clear and unobstructed view of the sky and wait a few more minutes than normal before starting your activity. 

Update: We've received reports that updating to iOS 11.3 has helped to improve GPS recordings on Strava.

  • Does this problem also apply to Apple Watch recordings, paired to an IPhone?

  • Fyi I've tried all the things on the list here and still hour an "as the crow flies" activity report today. Best of luck! -Jen

  • @Ken, we're mostly referring to the iPhone app recordings. If your watch uses the phone's GPS then this known issue should include you too.

    Sorry to hear @Jen, if you haven't already you're welcome to start a support ticket with us so that we can try further troubleshooting.

  • I’ve been having a lot of gps issues also. I suspect it has to do with Apple intentionally slowing down phones. I have iPhone 6. It just started acting up in the last few months on both Strava and rwgps. Taking it off auto pause seems to help a little but it’s not a complete fix.

  • I noticed this issue on Tuesday, since then 5 out of 5 recent recordings were half-complete. I tried turning the phone on and off but it didn't help. I will try with location services now and see if it changes something. I am not sure if the last point would make a difference (acquire satellites signal) since recording works fine at the beginning but then it stops mid-journey.

  • I've now had a similar problem on 2 runs this week (tue and today). It says GPS acquired but then doesn't seem to log the distance on the 2.7km. It does how ever log the time and knows an activity is happening.
    I know I ran 5k (I followed a preplanned route). It knows it took 27:31 mins but thinking I only did 2.3km

    I have taken screen shots if you need to see them


  • After turning the location services on and off it got better - recorded almost entire trip for me. However it still doesn't show what it saves, when I ride it shows the speed as 0 km and distance as 0 km and then the almost full distance appears when I save the activity. I say almost full because today it again lost the signal for the last ~300m.

  • I've encountered similar problems on my last three runs this week. I have tried most of the suggested troubleshooting steps above but I'll now try location settings before my next run and report back.

  • I’ve lost significant amounts of data on 3 of 5 rides since the last Strava update, including twice on one ride today. The app clearly turns off at some point so no data is recorded. Today’s second occurred after I closed the app, shut off my phone, and restarted both. I did not turn the location off and on. I originally thought that the problem occurred when I stopped at an intersection, but this second one occurred during a downhill. Other than your update, I had downloaded the latest update from Apple, which was designed to address two critical vulnerabilities. A side effect of this was that the devices could slow down. I think that happens. So the problem may lie with the latest Apple update. Hope it gets fixed soon.

  • This is exactly the issue that is happening to me too! It has done so for the last 4 rides I've done! I have taken to entering my data in manually to maintain accuracy. Will try the trouble shooting options suggested, and comment again with the result.

  • As said before I've had this problem (on 2 runs now) but it also happened when using google maps for navigation, it must be an apple issue

  • So after resetting location settings on my iPhone all seems to be well again. Had two successful runs now so fingers crossed it remains stable. Good luck to everyone 👍

  • same here just started happening to me last two weeks
    app also freezes and shuts down
    started happening before the last iPhone update

  • I turned the location on/off and lost less data than usual. Asking Strava to recalculate the distance left me 1km short, but other parameters did not improve. Just went for a 2.5 mile walk. A bar shows up on the profile, but the activity recorded 1min 10s, no distance. Apple just released a new update. I’ve downloaded it—fingers crossed.

  • Turning phone and location services off and on again didn’t work

  • I have given up using the app and now only manually input which really ruins the experience for me. I tend to run a 5k 5x per week and if I trusted the app, it picks up between 2.5 - 3.5k of my run and therefore gives erroneous timings.

    If it isn't resolved soon, I fear having to look for a new app.

  • Potential solution for some of you.

    Ok, I had a lot of the issues you all are speaking about. Intermittent recordings and even no recordings, just time.

    The fact is, a lot changed on my iPhone 6 in a short period. Bare with me: I replaced my screen at an after market shop, Real nice guys. I also bought a new case for my phone, an otter case for iPhone 7 to replace my worn out otter 6 case. It fit nicely and allowed all the ports and camera to be used. I went with it since the 6 cases aren’t really being stocked. Finally, I started using my wife’s Fitbit which was getting dusty in her night stand.

    First, I conducted the suggested location tracking resets with no luck.

    Second, I went back to the screen replacement store, they must have knocked loose the GPS antenna. They opened it and checked it for free, Claimed no problems and that the antenna is built in the board for my model.

    I Did the resets again, tapped on the phone like an old tv with rabbit ears, tried running with the app open on the screen the entire time, tried with Fitbit vs strava tracking, ran with and without music and even drove my car slowly around the neighborhood while tracking. Strangely, the car thing worked but I think my car gps was helping the very weak signal I had on my phone. Worked in the car should work without, wrong.

    Finally, MY SOLUTION: 5 days ago, I started a run and thought I’d test my luck with Fitbit. I realized 1/2 mile down the road i had tracked no distance, only time. I stopped in frustration and removed the new case and BOOM, signal to full power. Fitbit shows GPS signal in bars. If strava has that, I’ve never seen it but it’s never been important to me. Anyway, Could it be...YES, the remainder of my run tracked nicely. I’ve probably got 4-5 rides or runs since then through strava. They’ve all tracked nicely.

    Good luck, I know it’s frustrating.

  • Hello everyone,

    We are also tracking how the iPhone's wifi connection may be affecting the GPS signal. We'd be interested to hear if disabling wifi before and during your recording improves the data.

  • Gonna try turning on "ask to join other networks" under wi-fi. Maybe other networks are confusing fitness apps. Will try this before turning off wifi. Although I still think it is something apple did.

  • Two rides now & nothing recorded. Starts normal, says GPS acquired. Shut screen off like normal, place in pocket like normal. Then when I’ve return home & open my phone to finish it’s only recorded about 50 yards. Possibly when I’m back into WiFi range. Very frustrating. :-(

  • 3 runs in a row I've had major GPS issues with the app, i'm no hard core athlete but do find it most frustrating not being able to see my progress, I have an iPhone 6S, last two runs despite hearing the app working when uploading it has recorded no activity. Might it be linked to recent IOS updates? Like others I really hope a solution is found soon before I give up on it.

  • I've tried all suggestions and Strava will only have the time running and won't track run even though it has GPS signal. I will try disabling wifi while running (I am pretty sure i might have already done this as i don't tend to have wifi on the phone). Its getting frustrating so I am looking for another app as I also have a Garmin watch and that is failing to upload to Strava no matter what I do!

  • Had it freeze up on every run of 2018. I tried all of your resets and running with it out of its case.
    No change.

  • Just happened to me too after following these steps. Have only had one activity recorded this year. Turned phone on and off, had WiFi off, waited till I saw it had a GPS sync before I started running. Didn't not track anything. iPhone 6s.

  • Suffered for weeks now, tried everything poss. Are premium accounts suffering too??

  • Same here. Issues started around 2 weeks ago. Has always worked perfectly before on same device. iOS updated to 11.2.4 around that time so likely the cause.
    I start strava and the timer runs but no distance recorded. When I disabled auto pause I managed to get it started tracking, but it gave me some very random split times.
    My running buddy also having same issue - strava time runs but not recording distance. This seems to be a general fault with the app and iOS phones. What is the plan to diagnose and roll out a fix to the app..?!

  • So, two things seem to be helping me so far. fingers crossed.

    1. I turned auto-pause off. Because often the phone would not resume the ride after a short break.

    2. I turned on ask to join new networks. Seems like several times the ride would get cut off at the same spots. Maybe the phone was trying to pick up someone's network or a construction company or something near that area. idk

  • Finally a successful record! I used 2 phones: an 8 with the latest Apple updates and my old 5 that I can’t update past 10.3.3. I didn’t download the latest Strava updates on the 5. I opened Strava (My Feed), turned off my WiFi (Bluetooth not on anyway), then went to Record. I also used Beacon on the 8. Did one phone at a time. Left the house and started to record. It was a cold ride for about an hour so I didn’t look until I got home and stopped recording—but the ride on each phone was essentially identical, and both matched my bike computer pretty well. Looks like a WiFi issue. Will try again tomorrow. Anyone know how to delete a second recording of the same ride without deleting both rides?

  • I did every step you suggested (off/on, gps connection early, no other apps, location services off/on). It didn’t work. Same issue it starts timer but no distance tracked. I also updated to the latest iOS but no change. Strava worked perfectly on this device for a year, this issue started in mid January.
    When I TURN OFF AUTO-PAUSE it starts working ok.
    My mate is having the same issue with Strava on his android phone so it is not just an iOS thing.

  • Note that I have had issues just recently as well on my iPhone 6s. It is a Strava specific issue as I run Cyclemeter on my phone at the same time, and it records everything just fine. Very weird.
