I have tried everything to no avail, I have concluded that this app is not compatible with IPhones. ### 5/5 — Works well with my READ fitness watch *2020-02-26, version 1.82* No issues connecting via Bluetooth. Seems to track my distance more accurately than my iPhone by itself. My READ smart watch is basically a glorified pedometer (which is all I need)with the extra feature of being able to utilize the remote camera feature through this app. This is one of the main reasons I purchased the READ watch and I can snap a photo with the push of a button wirelessly from the watch. Very happy with what is provided because I don’t use the alert features, which causes my watch to beep when there is a phone call, and do not want my watch connected at all times via Bluetooth. One note; in first setting up the app you’ll need to enter your height and weight in metric units, so make sure you have that information available when starting the app for the first time. Update: could the developer add a timer feature which causes a five second delay between pressing my watch button and the app taking a photo. I don’t want to have my hand on my watch in every time I take a photo of myself. ### 1/5 — Garbage *2020-02-08, version 1.81* This app connected initially, but had the wrong time displayed on my watch. I couldn’t get the time to change through the app, so I deleted it and attempted to connect it again. No luck, and it hasn’t connected since! Throw this app away! It’s bull@&$!. ### 1/5 — READfit *2020-01-30, version 1.81* Does not work no features on here even to see incoming tex ### 1/5 — Watch and App *2019-12-31, version 1.81* It is nothing more than a watch and app you you can get at Walmart. Advertised as great. But it’s not. Wished I’d got a Fitbit. I’m sending it back. Thought it was different. App locks up and have to turn phone off and back on to get it to work. Sooo disappointed. ### 1/5 — Please fix profile issues *2019-11-19, version 1.81* Can’t update profile information . Willing to give you guys an chance to fix issue before negative rating. ### 1/5 — Trash *2019-08-21, version 1.80* It won’t reconnect ### 1/5 — Garbage *2019-08-16, version 1.80* Down loaded the app and it doesn’t have all the features it says it does. It only has the sports tab feature. Also when I connected my smart watch to it connected fine the first time. Somehow it got disconnected and won’t reconnect. Needs to be fixed. ## Frequently asked questions about READfit ### What devices does READfit support? READfit is available for iPhone, iPad, and iPod.
