Caldwell Precision Chronograph App Reviews

Does the app need an update after iOS 16.0? The app simply dosen't want to load anymore.....

Have the G2, tried synching using bluetooth didnt work until I read the constructions and sync'd up within app... Program worked great, after each group I saved and created a new group using a ladder affect to test loads in .2grn increments. I cannot seem to get the app to email me the saved groups data though. All the data is there and it goes through the motions to email or send sms but I never get the email or sms message?????

Does not work on Iphone 8 with iOS 11.2.5

I cannot get the environment conditions to come up on the app. It gives me a "N/A" for both temperature and pressure.

Works fine outside, slight hiccup in range you need to use the lights, wish it would rotate on my iPad as it is easier to read, haven't managed to connect to my Samsung Galaxy A5 yet. Outside on the range it worked great, gave me all the info I needed help in getting my reloads better.

Purchased the chronograph that this app is intended for and tried downloading the app and it just shows up a dark icon as if its still downloading or waiting to be. I tried to delete it and it wont come off my phone. Try to download it again and it just says "open" in the App Store as if it is downloaded. But when you hit open it does nothing! Very Disappointed to have paid that much money for the chronograph and cant get the app to work!

Version 1.18 refuses to load. I had previous versions and worked fantastic. So now i have lost everything. Thanks

Have had it out twice now and would never register anything when using the supplied phone cord. Bluetooth never would connect. Had to delete and reinstall the app because after I tried Bluetooth, it kept trying to connect with Bluetooth and wouldnt recognize the cord was plugged in. Will try it a third time whenever I get back out, but not holding my breath. Pretty worthless so far.

I opened the box and check that all the parts were there, they were. I read the instructions until I understood each step, then I took it out and gave it a try. I connected the 15 cord and opened the app on my iPhone 6s, turned on the chronograph all in the correct sequence listed in the instructions. Everything worked flawlessly the try, the only option I didnt try was the Bluetooth option. At this time it was not necessary since I had the 25 cord supplied with the unit. Im 100% satisfied with my purchase, I may invest in the lighting kit if it becomes necessary. Great product, I would recommend it to a friend for sure. RedDog

I dont know what you other guys are using but it worked perfectly for me on a iPhone 5c (iOS 7) and on a iPhone 5s (iOS 9). The only problem I have had is the factory cable attached to a Lifeproof adapter, fixed that with a 3rd party male to male threaded for Lifeproof case data cable.

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!

Overall this app does exactly what it claims to do. It records each shot velocity and keeps a running history of all shoe strings. Adding target pictures with each string is a nice touch. The weather updates currently do not work. It appears there was a change in this version to use weather underground, but temp and humidity show as n/a after a few second delay while the app tries to get current conditions. I shot 15 strings of 5 shots on Friday. Had 2 errors in reading and had to restart the chrono twice. I think those were chrono/weather problems - the app kept working. Suggestions for the developers: - when I start a new group and the chrono is connected, start recording. Dont make me tap "start" - fix weather lookup (Im guessing you know about that) - add humidity and altitude lookup along with temp and pressure. We have to write these down, so if you are collecting 2 of the 4 necessary environmentals, you may as well get all 4 automatically (or use absolute/station pressure & temp & humidity) - you have two fields for "notes" on each shot string. These are probably going to be for the firearm and the ammo. How about making a list where I can enter the firearms and loads and choose or not. I think this is what you are trying to do with "templates", but the UI of templates doesnt really match how most apps work so its not as intuitive to use as a customized list for each notes field. - show the notes fields all the time ... Dont hide them and make me tap the arrow to show the info Thanks

This works fine on iPhone6s with the cord plugged in. You must turn off Bluetooth (in the app! Not just your device settings!) before it will recognize a cord connected device, which is a bug the developers should fix. Recorded data well, with the cord being removed and reinserted several times as we switched stations during the day. Highly recommended, it is simple and works well to relieve the mundane effort from data recording. Took shot data at faster than one per second. Bright sunny day at over 95deg F. May not be the most accurate device, but seems good enough for my needs.

Everything works fine except I havent figured out how to use the camera and group size. Does this require a Caldwell Target Camera? Zero instructions came with the app.

I didnt have a problem with connection to my ipad. I had a problem connecting it to my iphone, but it was my fault. When you open the app for the first time, it will ask permission to access the mic. I clicked no and it wouldnt connect until i gave the app permission. The only thing that keeps it from 5 stars is the app will not rotate when you rotate the ipad. Very frustrating when i have it in the keyboard dock. If they fix it, it would be 5 stars all the way.

Overall, I am happy with this app, but I do have three recommendations for improvements (see below). I have been using this app with the caldwell chronograph and an iphone 6 (w/ IOS 8, 9, and now 10), connected together with the headphone cord. I like how the app stores the strings, allows you to edit them, add comments to them, and even email them for later editing in excel. My three recommendations for improvement are: 1: Allow the user to manually override the temperature and baro. press. Last night at the range, there was a 5degree difference between what temp that the app was pulling from the weather service, and what my thermometer was measuring. In the past, I have also seen differences beween my barometer reading, and the pressure that the app is pulling from the weather service. When these differences occur, there is no way to override it, so you just have to make a note in your log book, email youself the string, then manually edit it in excel. 2: Add a configuration setting where the user can choose to allow the phone to enter sleep mode or not. I have found that if you plug in the headphone cord first, then launch the app, the phone will stay on during the whole shot string and not go into sleep mode. launch the app befor plugging in the phone cord, the phone will go into sleep mode (after a short period of not touching the screen or buttons) and it will miss shots. Even if you plug the cord in first and launch the app. (to keep it from going into sleep mode), but then later unplug the cord (for example, to walk downrange and take a pick of your group size), and plug the cord back in without closing and restarting the app, the phone will start go into sleep mode after a short period of inactivity too. 3. Add the ability to manually add a shot to a stored string. The app lets you edit or delete a stored shot from a string, but it will not allow you to add a new one. This ability would be handy when a shot is missed because the phone went into sleep mode. This has happened to me a few times. When the phone sleeps, the chrono will read the shot and display the velocity on its screen, but the app will not store it because the phone was sleeping. In these cases, I had to record the shot(s) in my log book, then manually calculate the correct the average, SD, and spread because I was not able to add it to the string.

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.

Tried to connect this to my iPhone and also my IPad , when connecting to Bluetooth it states Pairing unsuccessful "CaldwellCrono not supported" pretty sad you release a product and it does not work like expected.

The app works well but would be nice to connect it to Dropbox.

This app wont work if I turn the location services on.
