Just tried to return to it … but it seems like the log in server is out… stupidly signed out and now I can’t log back in. :/ ### 3/5 — 建议 *2023-10-18, version 1.2.4* 建议增加定时开关机。 ### 4/5 — Software seems to be improving but too early to say *2022-08-19, version 1.1.0* I will give it four stars for now and update this review after using it for a while. ### 4/5 — App doesn’t show battery level when charging *2022-04-21, version 1.0.13* Like the idea a lot and it’s been useful. Minor quibble is the battery level of device is buried in settings and it doesn’t show you battery level while charging. ### 2/5 — Potentially Useful Device *2021-05-21, version 1.0.9* ... but poorly supported by the app. For instance, with the promise of reducing distraction, the app's Deep Work function is filled with distractions and expects you to concentrate while inhaling twice and exhaling once keeping pace with a metronome. Poor use of colors often making data and messages unreadable: light yellow font against a white background. On the history page, a blue graph tracks yellow data, blue also represents both calmness and tension. There's no thought of colors having consistent meaning. And that history, date specific page has tacked-on graphs of current data no matter what day the page heading says is displayed. Inefficient and inaccurate graphing. The app's history info that could be expressed in a simple graph is spread over four pages of meaningless shapes which to fully understand requires manual calculations. Indications shown in an hour may have occurred completely in another hour. A simple graph of focus might appear as a flat zero line or as maximally high with no vertical scale to warn users. The exact same data usually looks different in today's view of it from yesterday's view. The cumulative graph of focus often fails to match the data it's accumulating. The help text is wordy and redundant. With poor navigation: like straight line sequence with the only path to reach a specific topic is to start at the beginning again. At the end id a section you have to click a button to display the button to click to move ahead. They have a 100+ page document that tries to explain the app's use. It's necessary because of the app's design weaknesses. The document explains a page-sized flow chart in nearly a dozen places. The flow chart's message is that habits are habitual which doesn't require the flow chart or the 50 pages explaining it. Unfortunately this exhausting list is not exhaustive. There is much more wrong with the app. The Foci device, worn clipped to your waistband, can operate without the app. It vibrates to indicate various attention failures. Unfortunately the vibration is so weak I rarely feel it. ### 4/5 — Couple bugs but app functions great on main features *2021-03-02, version 1.0.9* My purple circles do not show any data when tapped, unlike the other colors which function properly on the daily focus circles screen. Also would love to see practical strategies when the different levels of approaches are suggested when encountering various loops. Like when it says check focus level 3 or whatever - would love a button that gives you a quick stands saying the practical advice we might find in the booklet - so if I am not with my booklet in that moment I can still try to fix my behavior then and there. ### 3/5 — A+ for the Foci device, but D for the app design *2021-02-09, version 1.0.9* The Foci device is amazingly accurate at picking up on how focused you are, but the app design is confusing and the font is tiny. I’ve had my Foci for a year now and still only understand the main page of the app that shows my real-time focus. I don’t understand and can’t find many of the other pages and can’t find any documentation to explain these other pages. Wish the developers would look at the Fitbit app to see how to design a clear, easy to understand app. This Foci app seems to be designed by nerds for nerds. ### 4/5 — Great App But Needs Dark Mode *2020-12-05, version 1.0.7* Overall a great app, but I would love to see dark mode made available for when I’m doing meditations in a dimly lit room. As one of the first backers of Foci they’ve come a long way. I’d love to see how this application evolves over time. It does take some time for the machine learning component to reflect more precise information. Patience is needed in the beginning, but worth the effort when used daily. Make dark mode available or let the user choose their own background color or upload their own background image and I’ll give the app 5 stars. ### 2/5 — It’s quite hard to set up *2020-12-02, version 1.0.7* I just received my FOCI from Indiegogo which I was really excited about. However, the pairing/ installation process was a pain. The app didn’t recognize my device and could only get there by removing and reinstalling the app four times. Also, it’s impossible to place my product without hurting my nails and impossible to remove the device without damaging my pants.. :/ So far not satisfied, but let’s see how this goes and I’ll update my review. ## Most critical reviews (10 lowest-rated) ### 1/5 — App stopped working *2026-01-12, version 1.2.4* The app just stopped working and I have tried to report the problem but the website is down too ### 1/5 — Setup Failed *2025-04-16, version 1.2.4* I have a brand new Foci and every time I try to sign up in the app, it says “Sign up failed. Please check your network settings and try again.” It does this on every single phone I’ve tried. I didn’t spend $100 for something I can’t use. Get back to me with fix or I reserve the right to file a court action against you in my jurisdiction. ### 1/5 — Unable to log into account *2025-04-08, version 1.2.4* Cannot access account or update device. ### 1/5 — Servers offline *2025-01-01, version 1.2.4* After using app for a few years, suddenly unable to log in. All attempts at contacting customer service fail. Appears out of business. ### 1/5 — Device synching is a big problem *2024-10-07, version 1.2.4* Even though it works fine once properly linked and synch but it goes disconnected or ran out of charge for few weeks there’s no way to get it back to normal. Then it becomes a garbage. No physical buttons ### 1/5 — Sadly won’t even load *2023-03-12, version 1.2.4* I get a white screen whenever I try to open the app. Rebooted the phone, uninstalled, reinstalled still nothing. Now I have a wearable that does nothing ### 1/5 — App opens, white screen, app crashes *2023-03-12, version 1.2.4* App opens, white screen, app crashes. That’s all. Device is now useless. Had it for two days. Great business model: sell device, confirm activation, provide no service. ### 1/5 — Full of bugs that make it unusable *2020-12-08, version 1.0.7* I have owned a device since the beginning. The developers put very little effort into fixing bugs. I have had several recurring bugs. Eg, the device gets associated with ‘another’ account, without me changing any login details, and I have to reset it and go through the lengthy machine-learning process again. Currently the device stays at zero percent focus no matter what I do. Contacting the developers just leads to excuses, like ‘your app is not up to date’; which it is. This was an extraordinary idea based on research — however lazy developers have ruined the implementation. ### 1/5 — Feels like a beta *2020-10-05, version 1.0.7* Really feel like I got a beta product which is a bit annoying. Nothing about how to use the product is clear, including the exercises in the app which don’t have clear instructions (as well as fade out before you’ve had a chance to read and digest them). As a result it’s not clear if it’s actually doing anything. The status in the app never seems to match what I’m actually doing or feeling so I can’t say if the device is actually working. Really cool idea but seems too early to have released. Hoping it gets better with firmware and app updates in which case I’ll be glad to update my review. But at this point this device is generating more frustration then focus. ### 2/5 — I’ve LOVED the foci so much since it first started but… *2022-10-08, version 1.1.0* I was an original backer of the first Foci. It helped me not only see trends in my daily energy levels. It actually was part of the reason I was diagnosed with narcolepsy. It would show massive amounts of fatigue throughout my days but I didn’t “feel” tired. Little did I know my normal level of energy was similar the amount of energy a person has after a 24 hour shift of hard labor. I was so thankful for this being so important to my life I quickly backed the foci 2 as soon as I could! But now the app and device has gone down hill so much. I’ve sent so many requests for help that usually just get marked as solved without ever responding. Right now the app will not update your deep focus time unless you close the app completely and reopen it. It can be annoying when you just want to see how your day is going. My latest issue of my foci 2 not vibrating at all for any of the streaks I usually have 2, the focus slip and fatigue. This is a massive issue for me because the fatigue notifications helped track and warn of narcoleptic sleep attacks. I know it’s not designed for that purpose but it really helped me track it. I reached out through the app feedback on the 29th I’ve sent 3 messages adding info to the issue as I find out more and still have heard nothing back… I seriously love this device so much but it’s almost become unusable and it’s so upsetting. ## Most praised reviews (10 highest-rated) ### 5/5 — 还会出新款吗燕子 *2025-12-26, version 1.2.4* 这个小玩意陪伴了我很久，如今它的电池已经不行了。上网一搜索大多的帖子都停留在了五年前，甚至七八年前，淘宝店也只有几年前的二手老款在卖。 今天我拆开了它，我想给它换个续航更好的电池，现在的蓝牙耳机的电池都可以续航很久了，40毫安的电池在现在真的显得太无力。如今我的设备都已更新到typeC充电口，我常常找不到它的充电线。 作为一双内观自己的眼睛，它没有替代品。如今网站已关闭，店铺已消失，app也登录不上，但我还是很想念曾经的小憩，和激动人心的金色心流时刻。 foci还在运营吗？有类似或者更好的产品吗？这个带我开始调整呼吸，开始冥想的古早AI设备，对我的人生有特别的意义。 ### 5/5 — Live activities *2023-12-19, version 1.2.4* Live activities would be really cool ### 5/5 — Great *2023-11-11* I love foci it’s really an amazing device. ### 5/5 — Excellent!! *2023-05-02, version 1.2.4* Love this companion app for use with Foci 2 wearable biorhythm productivity tech App does a superb job calibrating and monitoring my biorhythms in order to learn how to actively modulate my emotional state ### 5/5 — If you committed, it’s amazing. *2022-09-12, version 1.1.0* If you invest the time and use the app the way it’s intended it’s a game changer. You will learn how your body works and be able to focus better and for longer. 👌🏻 ### 5/5 — Great Innovation *2022-02-08, version 1.0.13* I started using Foci a year back and amazed to see impact on improving focus .So many improvements lately augmenting the capability and hope to see Foci improving life in a distracted world .Keep up the great work and looking forward to see more impact with updates 🚀🙏👍 ### 5/5 — Great product but here are the recommendations *2021-09-30, version 1.0.9* Guys your product is great for the price point Here are some of the recommendations 1. When is the update 20 coming out 2. Add a ML switch on/off button to turn off the device so as to not collect false data while standing up 3 I HATE REALLY HATE to take off the device while not sitting sometimes I even forget. Please guys there should be a turn off button in the app to turn the device off when not in use Otherwise it is a great product it is very very accurate and I love its focus feedback training ### 5/5 — Enjoying thus far! *2021-04-15, version 1.0.9* I’ve had it only shortly so it isn’t super calibrated to me yet, but I’m liking it! Hoping that maybe you could add an Apple Watch app so I can have a visual for when my focus changes. ### 5/5 — Awesome update! *2021-04-11, version 1.0.9* Well done guys! Have had Foci for a few months now and it just keeps getting better and better! Super impressed by the new emotions tracking from this release. Was wondering is there a way to have records for the negative states? Keep up the great work and can't wait to see what comes next! ### 5/5 — Studying for exams *2020-10-17, version 1.0.7* I got my FOCI for studying for this summer’s exams, and it was a big help in terms of alerting me when I was getting distracted (especially the vibrations), also when I was tired and needed to take a break. Now just started final year of Uni, and checking FOCI and using the biofeedback are key parts of my library routine! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
