Change the reading to j (joules) by tapping on the reading in end column and the reading is compatible to the readings of the chronograph although showing it to be “j”. Other than that an excellent app Would have given 5 Stars otherwise. Hope this can be corrected. ### 2/5 — Good device poor app *2025-02-22, version 1.3.0* The chrono is good but the app is poor as the data doesn’t match what is given in the chronograph, correct power on the device but the app says the power is lower than the device ### 1/5 — Airforce one *2025-01-09, version 1.3.0* As other users say the app is not accurate. If the maker of the app just check their maths I think it may work properly. ### 2/5 — Ft-lbs Well out! *2024-09-01, version 1.3.0* App and Chrono readings aren’t the same. FPS match on both Chrono and App but Ft-lbs couldn’t be any different. It’s atleast 6ft-lbs different. Chrono is 100% correct (AirForceOne Chrono), I know this as I checked against another Chrono. Also the App crashes often. Can’t seem to find an app that will pair to my Chrono that is stable and shows CORRECT readings. ### 1/5 — Just terrible *2024-08-22, version 1.3.0* Considering what a great little chronograph this app is absolutely applauding. So many faults to list. Biggest one pellet energy levels are different on the app to the unit. AirAbility ### 2/5 — Readings *2024-08-16, version 1.3.0* It’s shows a different ft-lbs reading on my Chrono than on my phone app….fps is correct on both Chrono and phone ( they match) but ft-lbs are 2 different readings and way off 🤷🏻‍♂️the actual Chrono works on my r10 but the Chrono is way out on my co2 pistol. I’m not sure if it’s an app issue or not but it definitely doesn’t like co2 pistols! ### 1/5 — Excellent device let down by the App. *2024-07-30, version 1.3.0* Fortunately, the device can be used independently from the App as it at best basic and at worst almost unusable. The instructions imbedded in the App itself are poorly written and a trial and error approach is required when attempting to set up and use the App. Not a problem for me, but anybody wanting to record and list the results remotely for later analysis will be extremely disappointed. ### 1/5 — Problem *2024-07-10, version 1.3.0* Still finding it hard to set grains up for 9.65 And average readings still showing metric not f/s and fb ### 4/5 — New update… *2024-04-20* The new update 1.1 is really nice as the app does not crash anymore when saving data and connection to Bluetooth. The only thing is outdoor/indoor mode can’t be changed from the app anymore so u have to press the + button on the chrono. Other than that this is a really nice accurate chrono paired with the app. ### 3/5 — App Crashing… *2023-09-17* Hello, the app keeps crashing if you use any functions like read data, connect to Bluetooth, saving and seeing data. (09/16/23) Otherwise the app works great and the chrono is very accurate. ## Frequently asked questions about Orcair Chrono ### What is Orcair Chrono used for?
