I only use it because I have to ### 3/5 — It works ok *2026-08-12* The one and only flaw for me, it signs me right out. Before either DoorDeck, I stayed signed for a few days and it was very convenient, specifically with everyday use. ### 1/5 — Older version was much better *2026-08-10* Unlocking runs very slow in comparison to the older version of the app. Also regularly has bugs that require a relog to give accounts access. I should not have to wait two minutes for a door to unlock when I scan a code / NFC and the location based unlock should not be buried under 4 buttons to get to when you have it listed as a favorite. ### 1/5 — Kicks you out weekly and forgets devices *2026-08-03* One of the worst physical security applications I have used **Developer response:** Hi Marimbas123, I’m sorry to hear you’re experiencing these issues. Could you please contact us at support@doordeck.com? We’ll do our best to resolve them. ### 1/5 — Just Awful *2026-06-24* Horrible experience using this app. Two biggest issues: - constantly logs you out - favorites are buried 4 interactions deep What’s the point of having favorites if I have to change screens and press three times to use it? I’ve gone back to just using my physical key because it’s more efficient. ### 1/5 — Great concept, rubbish execution *2025-04-22, version 5.3* Just doesn’t work, at least not quick enough to prevent rage setting in. And that’s before you’ve even got into the office! ### 1/5 — Shocking *2022-03-16, version 5.1* The app should do one thing right - open a door - but it manages to complicate that with regular login failures, and an onboarding screen that appears every time you log in. Support suggested it’s a Wi-Fi / 4G issue but I have Wi-Fi disabled and I still get stuck in front of the door once every three times. Very frustrating to use and the rest of the office agrees ### 1/5 — Appalling *2021-09-24, version 5.0* This app has literally one function and it can’t even do that well. It keeps logging out randomly (even with Wi-Fi off), every time you log in it shows the instructions as if it’s the first time, the widget doesn’t show anything but text even if I have favourite keys, sometimes you have to log out and log back in cause the keys don’t work… Seriously I’d rather have a physical key ### 2/5 — Nicer UI but still high failure rates *2019-10-23, version 3.4* Need to try about 5 times to get GPS verified. If GPS api doesn’t work well for you, why not just try collecting a list of Bluetooth and Wi-fi devices as alternative verification solution? ### 4/5 — Had issues - but was resolved by developer *2019-10-12, version 3.3* Encountered some issues but these were resolved by the developer who helped me out at 12am in the morning. Thanks Marwan - appreciate the help and quick support. ## Frequently asked questions about Sentry Interactive ### How does Doordeck work?
