A little clunky but works well enough. Installed on my iPad and it does not connect to Bluetooth. App settings does not show Bluetooth permissions, only microphone. Needs update for it to work properly with iPads. ### 1/5 — Does Not Work on iPhone *2024-03-21, version 1.21* Connects to iphone via official apple lightning to 3.5mm headphone jack adapter, and recognizes device in app, but does not transmit any data. ### 2/5 — Not soo much *2024-02-16, version 1.21* Ithe app worked great until I updated to iOS 16 and 17. Now it does not send the data to my phone… ### 1/5 — Does not work on iPhone 12 *2024-01-22, version 1.21* Tried everything and although says connected it doesn’t record strings or anything! Doing some research it seems most folk with updated iPhones/ lightning connectors can’t get it to work! Any chance of bug fix ?? ### 1/5 — Not working *2024-01-22, version 1.21* So far this has not worked I do have a brand new iPhone 15, and a brand new iPad. It’s not working on either one some of them. Other reviews seem like it may work on older phones and iPads. I hope Caldwell will get this issue fixed to where it will work on all devices. I think it would be very nice to be able to use the app to record averages and the shot groups. Come on Caldwell get your act together. ### 1/5 — App doesn’t support newer iPhone OS *2024-01-19, version 1.21* Advertised the app all over the box. But it doesn’t work. UPDATE THE APP OR DON’T CLAM IT WORKS WITH IT !!!! Finally working without app. Found it is sensitive to amount of light coming in. So if there’s not enough light or too much ERROR or nothing shows up. By the time you finally get it to show a reading ur done shooting all ur ammo. Really disappointed with this “chronograph “ for as long as it’s been available one would think some of bugs would be worked out. ### 1/5 — Doesn't work *2024-01-18, version 1.21* It won't pick up the chronograph via Bluetooth or plugged into my phone. Heaven forbid I have to write my velocities down. IPhone 13 mini. ### 1/5 — New update fixed ios16 but lost old data *2024-01-15, version 1.21* It now loads with ios16 and sees the chronograph but won’t record any data from the chronograph. Was a great product but it now is useless. ### 4/5 — iPhone connections *2023-12-27, version 1.21* On 12/27/23 I discovered that the adapter for iPhone to Chronograph was not working properly Never got the App to recognize the chronograph, connected indicator on app always Red Removed the connection at my iPhone and flipped it over and plugged it in, Indicator turned Green Repeating many times, Working one way, not the other Connection at iPhone bad or adapter connection bad, will mark adapter side that works and test in the field, Seems like the app should work now ### 1/5 — App doesn’t work *2023-12-20, version 1.21* Doesn’t work! Bought iPad adapter, but doesn’t recognize the Chronograph. iPad 102 OS 17.1.2. Real bummer. ### 3/5 — It works…sort of *2023-12-18, version 1.21* I was excited to use this app with my new chronograph and according to Caldwell’s website and the chronograph manual all items should’ve worked with my iPhone 12 Pro Max. Of course I had to use an adapter in order to connect to the chronograph. And after a lot of troubleshooting nothing worked. Even though the indicator on the app was green showing it was connected, it still didn’t work. So I tried it with my old iPad. It worked great! I do wonder what happens when I upgrade to a new iPad. Will it not work then. Not sure what part is the problem: the phone, the chronograph or the adapter in order the connect the cable to the phone. ### 1/5 — A waste of time *2023-10-18, version 1.21* App has not been updated and will not work on newer iPhone! ### 1/5 — App is useless *2023-10-02, version 1.21* Not even sure why they have this app, it doesn't do a thing! It tells me the phone is connected, and that's it, doesn't show any readouts, nothing! It's useless! ### 1/5 — iPhone *2023-09-23, version 1.21* Won’t work at all with I phone 14 is junk needs updated glad I wasted my money on the chronograph ### 1/5 — App will not log data *2023-09-17, version 1.21* This app shows it is connected to the iPhone but it doesn’t record any data ### 1/5 — Junk *2023-09-14, version 1.21* Groups not recorded. Ballistics info can't be added manually. Weather data won't work. ### 1/5 — Would not suggest product *2023-08-23, version 1.21* This app will not communicate with an IOS 16 or above as stated. Very dissatisfied with product do to this along with it being very finicky to operate in daylight. ### 1/5 — This absurd! *2023-08-22, version 1.21* How can y’all keep selling this product, with a worthless app. Fix it! I’m about to wash my hands of all Caldwell products all together and I have been using them for years. How many YouTube channels need knock this around before y’all make it right! I’m about to join in myself. DO SOMETHING or stop screwing people out of there hard earned money! I’d give this app no stars if possible and the Chronograph itself maybe two. If y’all want anything that’s worth the money go anywhere else seriously it’s a joke. ### 2/5 — Works but screen layout poor and a bit buggy *2023-08-13, version 1.21* Compared to say the FX Radar app ( which was terrible to start with ) the screens are poorly laid out and not that intuitive. Would help if the FPS screen was larger in use. Strange bugs ( unless I’m doing it wrong ), I shoot air rifles mainly in .177 but when you go to add new ammunition data it rounds .177 to .18 ! ### 1/5 — Bought adapter and still doesn’t work *2023-06-28, version 1.21* Purchased an adapter for it to work with the latest iPhone but I still don’t get any readings. ## Most critical reviews (10 lowest-rated) ### 1/5 — App Doesn’t Connect iOS *2026-07-03, version 1.21* I don’t often use my Caldwell chronograph while shooting. However, I have never once yet successfully connected the App with the chronograph for the many years I have owned it now. Despite having all settings “enabled” along with Bluetooth enabled. Caldwell clearly doesn’t care or support their product either by the lack of effort and numerous negative feedback. ### 1/5 — Does not connect to IOS 16. *2026-03-31, version 1.21* I am unable to connect my chronograph to my phone through the app. Even with all of the correct settings. ### 1/5 — Could’ve been great *2025-06-19, version 1.21* No way to stop and then restart a string. You have to waste time waiting for your firearm to cool off before you can continue. As opposed to being able to shoot strings from several firearms during a session. No way to load your firearm/string information before hand. ### 1/5 — Not for. iOS *2025-04-28, version 1.21* Simply does not work with newer version of ios. ### 1/5 — Huge disappointment *2025-03-23, version 1.21* The app doesn’t connect via Bluetooth, nor does it work plugged into the chronograph, no point in downloading. ### 1/5 — Doesn’t work *2025-02-25, version 1.21* App won’t read any data from my chronograph at all, shows connection as green but doesn’t display the speed ### 1/5 — Needs updating *2025-01-11, version 1.21* Works with iPhone X, but not with the newer iPhones! I give the chronograph four star, works 90% of the time! ### 1/5 — Does not work with newer iPhone *2024-06-05, version 1.21* Worked with iPhone 7 after I bought lightning connector. Finally got a chance to use it again and showed connected but occasionally said it was not connected to iPhone 13. Seeing other reviews this has been an issue that devs refuse to fix. Had to use one shot at a time and record results. Basically a chunk of plastic without all the data perks now. ### 1/5 — Does not work!!!! *2024-04-13, version 1.21* The physical chronograph itself works well, but the app doesn’t work at all even with the appropriate permissions allowed. I can open the app and it acknowledges that a chronograph is connected, but the app won’t recognize or register a single shot despite the chronograph showing a speed reading. Don’t waste your time! ### 1/5 — Will not connect with my iPhone 15 Pro *2024-04-03, version 1.21* I’ve tried everything to get shots read and it will not register any shots. The chronograph works great but the app is worthless to me at this point. (Got adapter for 3.5mm jack) still no luck connecting! ## Most praised reviews (10 highest-rated) ### 5/5 — Fix This App!!! *2023-06-25, version 1.21* Doesn’t work anymore. Since the newest iOS it wont connect via cable to the chronograph. I didn’t pay $100+ for the hardware for you to just not update the software. There’s people still buying this and it just doesn’t work. Fix this! Unacceptable ### 5/5 — New update fixed ios16 but lost old data *2022-11-28, version 1.21* Hi thanks for fixing ios16 compatibility. It however doesn’t see my saved groups. I have data going back a few years. Can you fix this please? ### 5/5 — Works on the XR with the apple adapter. *2019-09-01, version 1.18* I didn’t expect it to work from the older comments. I had no trouble using the apple lighting to headphone adapter. ### 5/5 — Love the app but... *2019-02-26, version 1.18* Now this app does exactly what I need from it but would love to add savings a picture of my group as well. ### 5/5 — Great app to track *2018-09-07, version 1.18* I have used this app on an old iPhone 5s and it works as expected. I have 5-6 different handloads ranging from simple 9mm and .40 to 5.56 up to .308. It's great to keep a description of the components used, COL, and powder weight to compare other variations. ### 5/5 — Love it! *2018-08-31, version 1.18* Works great on my iPhone 6s Plus and my iPad 2. Such an easy way to track the data quickly! ### 5/5 — Caldwell Cronograph *2017-11-24* Unboxed the unit, checked out all the parts, read the instructions, charged the battery, hooked everything up, turned it on and took some shots. Everything worked exactly as advertised. Couldn’t be happier and I’m glad I made the purchase. ### 5/5 — Camera *2017-05-10, version 1.18* I called...after you save the group open it up and hit the EDIT now the camera is available. Next after you take the picture you touch the pic and tap the points ### 5/5 — Chrono works as expected *2017-01-14* I bought this to measure my reloads and this chronograph works great. Tripod is sturdy, whole unit and app works great. The only downside I would have to say is the app in which we can add brands of cartridges and bullet size. It does not want to add three digits for bullet size. It will use the first two digits only. For example if I would insert 0.224 it will show 0.22 and for 9mm I would but 0.355 it would put 0.36. Also the app will not add to and existing brand. If I wanted to add Federal brand of cartridge it will create a new field. Also could add plated bullets brands or just played bullets to the app. ### 5/5 — Works Great! *2016-07-07, version 1.18* Chronograph shipped with a bad cable and did not work to start with. Call tech-support they shipped a new cable right away and everything works great! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
