Quite often have to unpair socks and re pair. Biggest bug bear is it only works with FaceID. So if you are in ski gear you have to strip off to alter any settings. If I could use my passcode it would be great. ### 3/5 — Socks go warm *2026-01-25, version 1.6.3* So far no issues and keeps my feet warm. Rather unintuitive app interface at times though. ### 4/5 — heated socks app — works great *2026-01-03, version 1.6.3* Use this app with my heated socks when I’m hunting, that works fine. Connect every time with the socks set the temperature easy to use not fancy just a basic app. ### 2/5 — Good Socks - Poor App *2025-12-09, version 1.6.3* The socks heat well. The app worked the first year, but now it will no longer connect to the socks. ### 2/5 — Help *2025-11-28, version 1.6.3* Please upgrade your app so it works. Love the socks!! ### 2/5 — アプリを開くと何故かiPhoneのVOLが上がる *2025-02-21, version 1.6.2* 2025/2現在、なぜかこのアプリを開くと、iPhone本体の音量がMAX近くになる。修正お願いします。 ### 4/5 — Toasty *2025-01-23, version 1.6.2* Love these socks, keep my whole foot warm. Must have boots on though. Great that I can access through phone. Used them all winter last year. Docked a star due to the app quit working this year. But I just deleted it and reinstalled and we’re back in business, hopefully it stays working. ### 4/5 — Funktioniert soweit *2025-01-04, version 1.6.2* Über das App-Design und die Übersetzung kann man sich streiten aber prinzipiell funktioniert die App so wie sie sollte. Bin soweit zufrieden. ### 1/5 — Poor *2024-12-29, version 1.6.2* The app doesn’t work ### 1/5 — No Updates *2024-12-22, version 1.6.2* Worked at first, but seems to break with iOS updates. App crashes on open now. Been like that for months. I need the socks during deer season. Maybe they’ll fix the app, maybe they won’t, but too late for me regardless. Can’t depend on it. Useless. ### 4/5 — App löschen und neu installieren *2024-12-22, version 1.6.2* Hat bei mir geholfen ### 1/5 — App no longer works *2024-12-22, version 1.6.2* App crashed w every time ### 1/5 — App geht nicht mehr *2024-12-13, version 1.6.2* Schade um die Socken ### 2/5 — Turns on it own *2024-12-13, version 1.6.2* Turns on before I turn them on so feet heat up too hot. ### 2/5 — The app crashes on iOS 18 on iPhone 15 *2024-12-02, version 1.6.2* When i had an Android the app worked Ok. Since moving to iPhone the app crashed on launch. PLEASE FIX ASAP. Not usable without app while snowboarding. Reaching socks with ski or snowboard gear on is not very easy ## Most critical reviews (10 lowest-rated) ### 1/5 — THIS APP IS STUPID *2026-05-12, version 1.6.3* The registration to leave a review/feedback doesn’t work unless you have something random and if you use a phone number it won’t work at all if you have a united states phone number because the area codes skip right over it it’s like they are not made for Americans. WHAT THE HECK!!!! ### 1/5 — Keine Verbindung *2026-02-26, version 1.6.3* Die App funktioniert nicht richtig und dem Support interessiert es anscheinend gar nicht. So ein Müll ### 1/5 — Junk App *2026-01-24, version 1.6.3* Do NOT buy these socks simply because the app DOES NOT WORK!!! ### 1/5 — HORRIBLE *2026-01-19, version 1.6.3* HORRIBLE!!! Didn’t even make my feet warm. The app was weird. Would not recommend ### 1/5 — Probleme mit Bluetooth Verbindung *2025-12-13, version 1.6.3* Jedes Mal, wenn ich die App starte, findet sie keine Verbindung zu den Socken. Leider auch nicht über Gerätesuche. Mein Workaround: App deinstallieren + neuinstallieren, danach funktioniert‘s einwandfrei. Sehr nervig aber wenigstens geht es dann. ### 1/5 — App won’t work *2025-01-19, version 1.6.2* The socks are great, but if you can’t manually get to them to turn them on you’re screwed. App will not open and I don’t have the option to update. ### 1/5 — App Not Working *2025-01-09, version 1.6.2* App is not working for IOS 18 ### 1/5 — Very poor *2025-01-09, version 1.6.2* The finding of the heated socks is awful. 99.9% of the time it can only find one sock. You spend ages turning it off, on, off, on and attempting to scan repeatedly in an attempt to connect. It’s pretty useless. ### 1/5 — Doesn’t open. *2025-01-05, version 1.6.2* It’s not working anymore the app. Work last year but not anymore ### 1/5 — App startet nicht mehr *2025-01-05, version 1.6.2* Nicht mehr nutzbar ## Most praised reviews (10 highest-rated) ### 5/5 — Норм *2026-02-21, version 1.6.3* Сделайте плиз чтобы заряд отображался в процентах ### 5/5 — Всё отлично *2025-07-19, version 1.6.2* Приложение использую с греющими стельками. Один ьольшой вопрос - а где отображается разряд аккумуляторов? Это очень актуально! Добавьте пожалуйста! ### 5/5 — Keine App-Steuerung ?! *2024-12-03, version 1.6.2* Die Socken kommen bei mir jetzt das zweite Jahr zum Einsatz und ich bin total zufrieden (Ski) Derzeit hatte ich ebenfalls das Problem das die App nicht gestartet wurde - Abhilfe war die App einmal zu deinstallieren, neu installieren und dann hat die App-Steuerung einwandfrei funktioniert! ### 5/5 — Neu installieren. *2024-11-27, version 1.6.2* Falls die App abstürzt: Löschen und neu installieren. Hat bei mir geholfen. ### 5/5 — Amazing *2024-11-17, version 1.6.2* I love how its so simple and easy to navigate 😄 ### 5/5 — Die app ist sehr gut aber es wäre schön wenn man eine Akku anzeige hätte *2024-01-08, version 1.5* Die app ist sehr gut aber es wäre schön wenn man eine Akku anzeige hätte ### 5/5 — Got the socks for Xmas *2024-01-04, version 1.5* I live in these socks & honestly the app is so cool, I like that I can set a timer for my socks lol I can’t tell if they sell products other than socks, if I could find some I would buy them, 10/10 ### 5/5 — Need current sock temp *2021-12-27, version 1.3* Current sock temp and battery life would be nice. If sock drops below certain temp the app should send an alert. So far I love them. It’s been two hours. One sock did disconnect. Just needed to close and open app and it reconnected. ### 5/5 — Just downloaded and tried app-Works perfect *2021-12-22, version 1.3* After reading the negative reviews I almost did not download app as I was able to turn on and monitor the soaks without the app (lights on battery tell you temp setting). I decided to go ahead and try the app, I ignored signing up, scrolled through the tutorials and the app connected the socks. Super easy to raise or lower temperature, set timer, and even express heat. ### 5/5 — Good *2021-11-26, version 1.3* Does what it says, controls the temp on the socks. Easy to use. Everyone else needs to lower expectations. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
