It needs to be able to be very accurate and it needs to be able to clic on the location and navigate in Google if it’s need it. I use this for my kids safety and is not that accurate, it lacks more options that are important. And also I’m paying for this service so you guys really need to consider improving the app. ### 2/5 — Worked for a day *2024-07-18* the app worked great for a day. afterwards app wouldn’t let us go in and said “error starting syncup tracker”.. no matter how many times we clicked “retry”. we tried uninstalling the app and reinstalling it.. it then wanted us to setup the trackers again even though we used the same login.. we put the info in manually (imei and iccid) because the trackers were already in the vehicles.. once these were put in all it did was show the buffering icon and nothing happened. idk if the app is down or what..(we tried on multiple phones too) but an app for tracking needs to be reliable. returning the trackers if the app doesn’t start working. ### 5/5 — Stolen trailer *2023-12-28* Around thanks giving day my trailer was stolen from a job site and thanks to the gps keeping record of last location I could recuperate my stolen trailer in less than 15 minutes right after me finding out it was stolen. **Developer response:** Thanks for the feedback and we're happy you found your trailer! ### 5/5 — Tracking basically anything! *2023-12-06* These trackers are exactly what I was looking for, I had find my family app but it’s slow and not that accurate. This will alert me any time the tracker detects movement and will get me up to the minute of the exact route that’s being taken; and the best part is it’s totally undetectable to the person or thing your tracking. The only downside is u do have to charge them fairly often, I was worried cuz they say there only good for 7 hours but they stay charged for a day or two. So if u want to track basically anything (the tracker itself is about as big as a cc just a LOT thicker) I TOTALLY recommend!! I LOVE this product! ### 5/5 — App freezes up *2023-11-23* App freezes up when entering password with 13 or more characters ### 4/5 — Tracker *2023-11-15* When it works it’s great and it doesn’t always work won’t track goes offline a lot doesn’t record tracking this is the fourth one we’ve had so far ### 5/5 — Customer *2023-07-11* This product has been helpful to me in many ways. I am able to leave it at home when the children are there. I take it to work with me. I just like it. ### 5/5 — Amazing tracker and works great! *2023-07-10* This is an amazing LTE tracker and works great. It gives me an accurate location and helps me to track my stuff. I will recommend it to my family and friends. ### 5/5 — My motor scooter *2023-06-21* I finally have peace of mind sleeping at night. I used to wake up thinking my beautiful brand new motor scooter would be gone due to someone stealing it. Now I have the Syncup tracker and it will notify me if there’s any movement and show it’s exact location. I dare someone to steal it now.! ### 5/5 — Very accurate *2023-04-26* Locations are very accurate ### 3/5 — Fix *2023-04-05* It doesn’t snapshot movement automatically and save it for you like if your asleep and are unable to track. ### 5/5 — Chad *2023-02-14, version 1.13.1* It very nice but the tracker needs to pin point fast ### 2/5 — Awesome (Not Really See Update) *2023-02-13, version 1.13.1* I don’t know why this device isn’t more popular or why there are negative reviews. Works great for me. Got four from T-Mobile. Followed initial startup and setup. Downloaded app. Set up area boundaries for home, work and school. Notifies me when our vehicles come or go from each. Rarely is the accuracy a little off where the tracker shows its position a couple hundred feet from where it is. Response time is usually good. Rarely more than a minute delay. Battery life is about 5 days with normal usage. Charges from 5% to 95% within an hour. You could use in vehicles, backpacks, luggage, computer bags, clothes pockets, or on a pet collar. I’m super impressed. Highly recommend. If anything, they could try to improve the precision and response time over the next updates. Edit1: Reducing from 5 to 2 stars after my monthly bill went up by $100. TM charges to use these and the billing comes in the form of a fee per text message that these gizmos apparently send out. They didn’t mention that when giving us the free trackers. Nope. I canceled the service and returned. They were a fun toy for free, but they aren’t accurate enough and update with too long a delay to pay anything for these, let alone $25 per tracker per month. Edit2: TM: I already got the charges fixed. These devices added lines to our plan with numbers we had never seen and sent texts at a rate of 2 cents per message. You are being either deceptive or ignorant with how that work. Since returning my Syncup Trackers, I got AirTags that work better for $0 per month. ### 5/5 — Not loud enough *2022-12-26, version 1.13.0* It works great, but you simply can’t hear it if you’re more than 5 feet away. ### 4/5 — Works good but takes too long to refresh sometimes *2022-10-09, version 1.11.0* UPDATE: I am happy that I received help after voicing my experience with the tracker and they ended up figuring out the reason for the tracker not charging, and there seemed to be an issue with the charging cord. They sent me a new one and it started to work again. What was weird is that this issue happened multiple times and would charge if there was still battery left, so I guess if the charger is defective and the tracker has no power left at all, it wouldn’t work properly. It only would work if there was some battery left. I am so glad to finally have this issue resolved! The only reason I updated my review to 4 stars instead of 5 now is because the tracker really lags sometimes and there were days where it would take 10 minutes to refresh. Other than that, it does work as intended. I am absolutely so sick and tired of my sync up tracker just not working if it ever dies/ runs out of battery!!! This is now the THIRD time I am having issues after it runs out of power! The first time, I didn’t use for 2 weeks and when I put it to charge, it just stopped working and had to get a replacement. It works fine until I accidentally let the replacement run out of power, since I wasn’t using it for when school was out, and when I tried using it again, same thing! I let it charge for a couple days, but it just wouldn’t turn back on! Then I had to get ANOTHER replacement for same thing!! Now, I forgot to charge over the weekend and it’s only been offline for a few hours, I put it on the charger… low and behold… not turning on!! This is just ridiculous!! I MUST always remember to charge and NEVER let it die, or else I have to keep replacing it, and process for it is sooo long too!! It takes so much of my time to do it! I am not only mad at this stupid tracker for not working just because it didn’t get charged right away, but also mad at myself for letting it die knowing this may happen yet AGAIN!! Ugh! I’m so mad I tell yah!! Like I can’t believe no one else having this issue, but yet it’s happened to me 3 times in a row now! Ridiculous! ### 5/5 — Eow *2022-09-19, version 1.11.0* I’m like to use the syncup tracker app ### 5/5 — Muy bien *2022-09-14, version 1.11.0* Muy bien ### 3/5 — Useful *2022-09-11, version 1.11.0* I use this for tracking my baby’s car seat. I do wish the light detection worked better. ### 4/5 — It really works *2022-09-08, version 1.11.0* It has been accurate and reliable, even in sheltered areas. The battery life is rather disappointing though. ## Most critical reviews (10 lowest-rated) ### 1/5 — App won’t open *2023-11-01* After downloading the app it freezes when I type my password in. Happens when autofilling or manually putting it in. I’ve deleted and redownloaded the app and rebooted my phone multiple times and still can’t log in. The app always freezes and crashes at the login page. ### 1/5 — Worthless *2022-08-29, version 1.11.0* This thing goes offline everyday rendering it useless. Customer service is not helpful at all. ### 1/5 — Motion alert feature not working *2022-03-22, version 1.0.6* The Motion Alert has stopped working. The feature turns itself off after being turned on. Needs bug fixes and improvements. This is sub standard. ### 1/5 — Frustrating *2022-03-02, version 1.0.6* I’ve only had tracker a month and it ran up my bill $200 plus. Next bill has been adding up again. Turned it off and well going to have to cancel service to it. Very disappointed, I had to upgrade to this new tracker cause previous one was not going to work and well was not expecting it to cost me this much. Makes no sense to be charged for text messages on a tracker when already paying for data service. Wonder if anyone else has had this issue, but apparently I’m the first. This is very frustrating and disappointing. App doesn’t even send me notifications. **Developer response:** Hi Cordova, sorry to hear about the issue your experiencing. This does not sound normal. For questions about your billing please call Customer Care at 1-800-937-8997 ### 1/5 — I don’t live in Canada *2022-02-09, version 1.0.5* Any time I try to set a geo fence it says the address is in Canada and doesn’t work. The only alerts I get are for low battery. There are serious issues with the app and the people at t-mobile say it’s been terrible working with these things because of horrible support. The app doesn’t work properly and the developers haven’t fixed it. **Developer response:** Hey FFFanatic101, sorry to hear about your current issue. Can you email us at syncuptracker@t-mobile.com so we can learn more about what is happening and help fix the issue. ### 1/5 — No Spanish? *2022-01-17, version 1.0.5* This app doesn’t have Spanish functionality which limits it for use for Spanish speakers. Is there an update coming for it or is it just stuck on English only? ### 1/5 — I can’t access *2021-12-06, version 1.0.5* I can’t open the app it’s telling me it’s already active in a different account it’s not other way for me to go back for different options ### 1/5 — Great product; app has issues *2021-08-18, version 1.0.3* The product works great when the app works. For some reason I’m consistently getting a blank screen every time I open the app. This happens frequently but not always. I can shutdown the app. I can delete it and reinstall it. Nothing works but then POOF one morning it’ll work again. It defeats the purpose of the tracker if the app isn’t working. **Developer response:** Hi Mrose34, sorry to hear about your issue. Can you email us to discuss the issue further at syncuptracker@t-mobile.com ### 1/5 — App issues *2021-08-12, version 1.0.3* No, but the app does not work. Reaching out to “T-Mobile Team of Experts” did not help either. Complete waste of money and time. ### 1/5 — App required rebooting phone to work *2021-07-28, version 1.0.3* Had to reboot phone for it to work. App hung up after downloading and launching ## Most praised reviews (10 highest-rated) ### 5/5 — Found a thief *2024-09-21* I am very pleased with the GPS tracker because it helped me find a thief in my company who stole a very valuable tool and denied it over and over when I asked about where that tools at however because he had no idea that it was had a GPS track after denying it multiple times to my face I confronted him about that the tool had a tracker device in it and I was able to locate the tool going from the place of business to multiple places and also he ended up at a pawnshop however the battery did die so it stopped tracking but it was good enough that I was able to recover my stolen tool ### 5/5 — About my mom *2024-08-09* So, she is in her first stage of dementia and it’s really hard to keep track of my mama even though she’s got my dad there. I’m still 2 1/2 hours away from her. Never when I thought that this time would come, and I am so grateful that there are devices out here up until I can uproot and move up there with my parents to take very good care of them. I am so grateful for this device and for all the people at T-Mobile that help me set it up,. 🙂❤️ ### 5/5 — So far good *2024-07-12* Location accuracy is only off by about 20ft so it should be fine since I have it tracking my car. ### 5/5 — So far good *2024-07-10* Location accuracy is only off by about 20ft so it should be fine since I have it tracking my car. ### 5/5 — Great product to use *2024-06-22* This is a great way to track your miles on your vehicle when you use your car for traveling for work and not the company vehicle. Very helpful tracking for your mileage reimbursement. ### 5/5 — Use as dog tracker *2024-03-29* I use three of these trackers to keep up with my three dogs when I take them to the country for daily walks. I don’t think they were designed for this but they work better than any other trackers that I have used. I put them in small ziplocks (my dogs like to play in the creek) and put them in collar pouches. There are features I would like to see added but, overall, they work very well. They allow the dogs roam with peace of mind for me. ### 5/5 — Far more accurate *2024-03-27* Excellent more accurate and little bulky for my small dog but managed to make it work. Plus you can’t beat the subscription cost of $2 (on a promotion) for tracking. ### 5/5 — Sun up tracker *2024-03-26* Other than the issue with saying onboarding one night and not showing the location it’s a good app just needs some time to be stable ### 5/5 — Moving tracker *2024-03-17* Would like to see the tracker in moving status permanent instead of having to keep turning it on **Developer response:** Thank you for your feedback! To keep the Tracker in "moving status" permanently, you can enable Quick Tracking mode in the Advanced settings when editting the Tracker profile. This way, you won't need to manually refresh the location each time you open the app. The SyncUP Tracker team ### 5/5 — Works as intended! *2024-02-25* Love my trackers! I always forget my bag and belongings so it’s nice to stick one of these in there and they have a battery life of about 5 days or so. Charges pretty quickly too! Go by your local T-Mobile store and check them out! I got them as a bundle! 🤴🏾🙈💵 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
