It needs an update. ### 1/5 — Disconnected but says connected *2025-03-08, version 3.8.2* Why does it constantly say it’s connected when in fact it’s disconnected? ### 1/5 — Bug regarding on and off *2025-02-04* VPN is not turning off despite turning it off from the control Centre, it automatically reconnect somehow, so I always have to go back to the app and log so that I am not accessing personal things on company’s VPN ### 1/5 — complicated and bad *2024-12-31, version 3.8.0* very complicated. It makes my connection unstable and also I feel like hacked into my phone:) ### 1/5 — Complete garbage *2024-10-17* Ever since the company made us start using this one. It has been nothing but garbage does not maintain its connection. Have to re-authenticate regularly says it’s connected and then it’s not doesn’t work but well with zoom meetings says I have no Internet access sometimes sometimes I have to disconnect the VPN and then go on the zoom meeting, trying to get company to change total garbage ### 1/5 — Awful *2024-10-11, version 3.7.3* Our company forced us to use this malware. Time to look for a new job. ### 1/5 — Disconnected but says connected *2024-08-26* Why does it constantly say it’s connected when in fact it’s disconnected? ### 1/5 — Garbage *2024-07-08, version 3.7.2* If there ever was a piece of garbage app made this is it Forced to use it for work. useless ### 1/5 — Has always been a mess *2024-05-07, version 3.7* Barely worked before and now REALLY doesn’t work. Gr8 job! ### 1/5 — Never great, but now unusable *2024-03-12, version 1.9.12* Connecting to a VPN from this app was always a challenge, not so much because of security but because of the buggy way it interacts with the OS, and the inscrutable way in which it decides to actually re-authenticate a login. As of the most recent updates, though, it's become almost completely unusable. It wreaks havoc with wifi connections - disconnecting perfectly usable wifi and throwing my device back to LTE, and then, with internet access gone, refusing to connect to the VPN. It will show as "Connected" but mysteriously not allow any connections, nor prompt to log in. "VPN on demand" does not appear to actually communicate with the app anymore. And there are no error messages to explain anything that's going on. It's garbage. Complete, utter garbage and frustration. What I don't understand is why it's so useless on iOS when the Mac version continues to function perfectly well. ### 1/5 — unable to uninstall *2024-03-05* poor ### 2/5 — VPN always shows connected *2023-12-23, version 1.9.11* The VPN always shows connected when I disconnect. I have to log out in order to disable it. What’s a better when of doing that? ### 1/5 — This company should shut down *2023-10-15, version 1.9.10* This company does not know to make appropriate VPN software. It takes hours to comedy to the internet and get authenticated ## Most critical reviews (10 lowest-rated) ### 1/5 — No reason for certain blocks *2026-08-07, version 4.5.1* Blocks regular use items like Amazon Music. ### 1/5 — Erratic *2026-07-28* It need a big update, it can’t drain the battery this fast plus how it fails to connect multiple times, with my 17 pro max is a nightmare, with my 12 pro max works better. ### 1/5 — Too many conflicts *2026-02-25* This vpn causes CarPlay to crash and conflicts with many other apps. Sunbelt needs to drop this app ### 1/5 — Drains battery *2026-02-12* Zcaler consumes way too much battery in the background especially using on the iPhone air. I have had to disable it. Can the developers look into this battery drain, most of my friends also have this same issue. ### 1/5 — Battery hogging *2026-01-29* It running in background all the time, and consuming battery. For older devices it is nightmare. ### 1/5 — Can’t turn off VPN *2026-01-05* There’s no clarification on how I can stop the vpn, very shoddy UI ### 1/5 — Client connects / disconnects often - local servers throttle traffic - since Aug 2025 *2025-10-22, version 4.3.6* Client connects / disconnects often - local servers throttle traffic - since Aug 2025 - changed providers and countries even from Canada to US - nothing changed. App is fine - backend needs to be looked at. ### 1/5 — VPN always on and consuming lot of battery *2025-10-12* VPN always on and consuming lot of battery ### 1/5 — The Glacial Guardian of Your Data (and Battery) *2025-08-08, version 4.3.4* If you've ever wanted to experience what it's like to browse the internet through a melting glacier, zScaler is the perfect app for you. Imagine a security solution so committed to safety, it slows your connection down to pre-broadband speeds — just to make sure every packet gets a proper pat-down by digital customs. Speed Let’s address the frozen elephant in the room: performance. zScaler operates at the speed of trust… which apparently is slower than erosion. Opening a webpage feels like watching continental drift — fascinating in theory, excruciating in practice. Need to quickly check your email? Better send a carrier pigeon, it’ll get there faster. Privacy Installing zScaler on your phone is like inviting a mall security guard to live in your house. Yes, they’ll watch over things — but they’ll also go through your fridge, read your texts, and maybe take notes on your playlists. Full device VPN? Sure. Certificate installation? Why not. SSL inspection? Of course. At this point, it’s unclear who the client is protecting you from — but it’s definitely not itself. Battery Life While zScaler claims to keep your phone secure, it also helps you disconnect... permanently, by draining your battery faster than Instagram on a 5G loop. One moment you’re sending a WhatsApp message, and the next you’re frantically searching for an outlet in a coffee shop to charge your phone. Final Thoughts If you enjoy slow connections, questionable privacy trade-offs, and having your phone run hotter than your firewall logs — then zScaler is the tool for you. It's like carrying an overzealous IT auditor in your pocket, complete with a clipboard and a deep mistrust of your DNS queries. ### 1/5 — Terrible *2025-04-17, version 4.3.0* Always asking to re-authenticate and doesn’t let you. ## Most praised reviews (10 highest-rated) ### 5/5 — Works well *2026-06-09, version 4.5.1* No issues observed ### 5/5 — Works great now a days *2026-06-08, version 4.5.1* All previous issues have been addressed ### 5/5 — Fantastic work *2026-01-28, version 4.4.3* Although older versions had flaws, the latest version is superb and runs seemlessly with minimal battery consumption, no lag on wake up and no issues I’m aware of. Great work Zscaler. ### 5/5 — Good mobile implementation of the ZCC *2026-01-12, version 4.4.3* Works very well. Similar experience to the desktop client. ### 5/5 — App works exactly as it should *2024-09-22, version 3.7.3* App does what it’s supposed to do. Creates a iOS system wide VPN and then routes traffic through it. Some of the bad reviews are likely from people who don’t even understand the basic concept of a VPN, but are forced to use it for work - and then are frustrated because their device is behaving in a way they don’t understand, but is perfectly consistent with VPN. Contrary to what others said…..yes, you can go into the VPN sections of Settings and toggle this on and off just like any VPN app and switch between it and potentially other VPN apps exactly as you’d expect. ### 5/5 — Keeps my iPad safe and allows me to access corporate resources *2024-09-08, version 3.7.3* Very stable. Fast internet access on both my iphone and ipad. Battery life impact is minimal since all the agent does is intercept packets and decides whether to send them to the internet or to corporate resources. ### 5/5 — An Admin’s Perspective *2023-12-21, version 1.9.11* Zscaler is going to get negative reviews, because the people using it are the people it is securing. Security is rarely convenient, but I find the trade off in convenience here to be acceptable. It connects without issue, and speeds are acceptable. Also the ability to configure it via Intune to automate the setup process is *chef’s kiss* ### 5/5 — Working great *2022-08-30, version 1.8.8* Seamlessly connect to both internal app and secure my connection to the internet. ### 5/5 — The App is Working Properly *2021-09-06, version 1.8.6* I am going to say, that the app is working OK. I have no issues logging into Zscaler. Keep making more VPN features. ### 5/5 — Works as mentioned *2020-07-26* Secure VPN with great speed. App interface is also easy to understand. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
