I’m glad they quietly admitted defeat but they’ve left every early supporter out in the rain. Shame on them. I work in tech and have not seen such disregard in a long time. The earlier generation has a BT antenna. Make it work. -- Ajkarnas, 2025-02-20 ### ****- "Karoo is excellent but needs HealthKit support" This app and the Karoo computer has been getting some great updates lately. Please add native HealthKit support. That’s the key missing piece that holds me back from a full recommendation for Karoo. -- Paulnerd, 2025-01-10 ### *---- "No Karoo 2 support" Why in the world would you not make this backwards compatible with the Karoo 2? This has been a feature that has been asked for for so long. Why would you alienate your loyal customers? Please fix this horrible oversight. Your biggest competitors have had this functionality for years. -- lubdubrn, 2024-11-10 ### *---- "Karoo 2" Doesn’t work with the Karoo 2. What hardware limitation exists in the Karoo 2 that it can’t be used from this app? It smells of planned obsolescence to me. So much for being a Hammerhead fanboi. Time to move on… -- cygnl7, 2024-10-05 ### *---- "Karoo 2 Not supported" Excited they came out with app only to find Karoo 2 not supported. -- djs21-79, 2024-09-26 ### *---- "No Karoo 2 support" Disappointing that hammerhead hasn’t made app support available for the Karoo 2. Way to leave your loyal customers out in the cold. -- Dynort, 2024-09-03 ### *---- "Short-sighted" I won’t even consider upgrading my Karoo 2 to the K3 until SRAM commits to making this app compatible with the population of K2 devices that otherwise work perfectly well. -- Switching to Weather Bug, 2024-08-09 ### ***** "Very Happy" When my original Karoo 1 battery finally died I updated to the new 3rd generation Karoo. I love it and and love this app. Being able to read text messages on the Karoo is wonderful, quick checking how charged it is when I'm too weak to get out of bed is fabulous, but my favorite feature is sending POIs markers from my map apps. It's quite handy when I get lost, I'll get out my phone, find the address and send it to the Karoo and be on my way. While I'm looking forward to future features, I'm delighted at where it's at now. Most of the negative reviews here are from disgruntled K2 owners, and I understand, I know its disappointing that the K2 isn't supported, but that's no reason for one star reviews. I'm delighted with this app and proud of how far Hammerhead has come over three generations, I'm excited to see how far they can go under the SRAM brand. Right-on yall, keep up the good work! -- Sighing Mage, 2024-08-03 ### ***-- "Love the product but not the App" I was extremely impressed with how well and quickly the Karoo paired with my third party components. I don’t like how the only way to assess the ride data is through Strava which does not always provide the most accurate depictions or go as in depth of the workout. I think that this is something that the app would be better utilized for. The details that Wahoo provides is impressive and something that is very replicatable. Why have all these things on my display if I can’t see any of it afterwards? -- ¿ñÿgmā?, 2024-07-30 ### *---- "Brand new K2 not supported" Seriously, no support for the K2 I bought a couple months ago? Setting up for the first time for a 7 day bike-packing trip and already no app support. Pretty good way to loose SRAM customers! -- BackCountry717, 2024-07-30 ### *---- "Another hacked off K2 user" Yes, I like the K2, but it’s despicable that the phone app only connects to the new “Karoo”. And it’s double despicable since we already know the K2 is bluetooth capable and Hammerhead can release software updates on the fly. Note to SRAM marketing knobs, this ISN’T the way to build customer loyalty. -- Schmuck in a truck, 2024-07-24 ### *---- "Worthless K2 and app" Completely useless K2 now that they’re K3 is out. I re-downloaded the app only to find it has nothing for the K2 I just spent $500 six months ago. Then my PW stopped working and now I can’t log in to website. Though the site keeps telling me it’s sending me an email to reset my PW, nothing arrives. Nothing in spam either. I’m so frustrated with the whole system I think Im going to take the loss and get a Garmin like the rest of the TDF followers in my group are using. SRAM should be ashamed of this technical mess. It is everything BUT user friendly. -- joe.sonja, 2024-07-18 ### **--- "Karoo 2 doesn’t connect" I was so excited to see that Hammerhead finally had an iOS app. To my disappointment this only works with the Karoo 3 apparently, not the Karoo 2 that I bought for $400 just six months ago. Since I won’t be throwing away my basically new K2 any time soon, this app is useless. Hopefully they will make it compatible and I’ll be changing this review in the near future. Still like my K2 though. -- JonnyNC, 2024-07-13 ### *---- "Only latest Karoo supported." This is an absolutely a garbage strategy. Disrespectful to customers to say the least. And folks with latest version now seems like will also be left behind when the new karoo comes up... -- ffc1902b, 2024-06-22 ### *---- "Unable to Pair New Karoo" The only way to use the app is to scan the QR code, but this doesn’t work. When I attempt to scan using the app, nothing happens when placing the QR code within the camera field. I am able to sync the device to my account if I use the native camera app, but the companion app is unavailable to use. -- mattrmay, 2024-06-12 ### *---- "Evidently no loyalty to customers" I have a Karoo 2 that’s a little over a year old, and now there is no support app if I get a new phone or want to use a tablet. I bought the Karoo because of its reputation and usability internationally. Now not so much. -- Thequietguyonthebike, 2024-06-07 ### *---- "Doesn’t work with Karoo2" I don’t see any good reason this does not work with the Karoo 2. This “only compatible with Karoo” nonsense, feels like a money grab. -- Studyfortruth, 2024-06-03 ### *---- "Doesn’t work with new Karoo" Refuses to pair, says requires the new Karoo (which I just bought). -- TRC1956, 2024-06-01 ### *---- "Does not work with Karoo 2" Disappointing, even more so because Hammerhead sent me an email to go try the new companion app. -- Andy "nickname taken" R., 2024-05-31 ### *---- "Inexcusable to not support previous hardware" There’s no good technical reason for the lack of support for previous devices. This is just a naked attempt to drive users to purchase a new device that they don’t need. I was considering upgrading, until now. -- occipitr, 2024-05-30 [View all Hammerhead Companion reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Hammerhead Companion Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Free | Germany | Health Fitness | #475 | ## Apps Similar to Hammerhead Companion -
