Not impressed ### 1/5 — Unbrauchbar dafür 2 € im Monat gespart *2023-07-16* Sorry, aber wenn man nur mit Airlineaccount akzeptiert wird, kann er sich die App hier sparen. Adresse 2x abgelehnt und auf Erklärung nicht reagiert. Danke auch 👎 **Developer response:** Hi, CTOT app is only available to aviation employees, we invite you to use other publicly available tools if you are not working in aviation. ### 1/5 — Can you fix the bug, please. *2023-07-11* Doesn’t find all the flight. **Developer response:** Hi, Please send an email to contact@ctot.app if you encounter any issues with the app. Kind regards ### 1/5 — Useless app *2023-05-30, version 5.4.5* Unusable app, just gets stuck on the logo for hours. Unusable waste of money. ### 1/5 — Registration process really bad *2022-08-19* It’s not possible to register with a private email address, really bad. I’m an airline pilot and don’t have a company email address **Developer response:** Hi, Unfortunately the data is not open to the general public. Therefore it is not possible to approve accounts with a private email address. I can only suggest that you contact your airline and ask for a professional email address. ### 1/5 — Doesn’t work *2022-07-26* After inserted the code, get a white screen. Tried to reinstall but no changes. **Developer response:** Hi, could you send an email to contact@ctot.app to sort your login issue ? Best regards ### 1/5 — Can’t use the app *2022-07-20, version 4.8* My activation request goes un-answered. Can’t use the app. ### 1/5 — Doesn’t respond to activation request *2022-07-09, version 4.6* Have downloaded the App but developer doesn’t respond to activation requests… ### 2/5 — Yet another subscription *2023-09-22* The app subscribes to the nuisance of asking a subscription for everything. Thereby excluding occasional users who would need it only a few times per year. The trial period had expired before I even had an opportunity to try it out. Deleted the app again. ### 2/5 — Payment/subscription issues *2023-08-25, version 5.6.2* This app was handy while it worked on the free 1 month trial. However, when it came to subscribing via Apple Pay, the payment took a number of failed attempts before it could be processed. When it was eventually accepted and the money was taken, it was not recognised by the app. It tried to restore purchase, but this remained white and did not function. Unfortunately unusable. ## Most praised reviews (9 highest-rated) ### 5/5 — Excellent *2023-10-19* Super outils pour suivre les nombreux slots. Je suggère une petite amélioration, l’ajouter en complication sur Apple Watch. On garde le système des pastilles (verte et rouge) avec l’heure CTOT est là je pense qu’on atteint une appli ultime. ### 5/5 — Excellent ! *2023-08-26* Super appli facile à utiliser et très réactive. Bravo Serge pour ce Dev ! ### 5/5 — Nice App *2023-07-06* But please sort messages from most recent to oldest. Like this we don't have to scroll to the bottom each time we want to check for new messages. Thanks :) ### 5/5 — Great slot awareness and much more information *2023-06-12* The app is really good, always ahead of the ACARS data and you can see your filed route and the sector which is likely to cause the CTOT. You can also check if you are on a CDM airport and you can even see if the controller has sent a ready message. ### 5/5 — Useful for line operations *2022-07-16, version 4.7* For the sake of a couple £/€ a month this app makes the day to day airline pilot life that little bit simpler. We can see slot delay reasons etc all in the app and see which sector is causing it as well. Well worth it. ### 5/5 — Super *2020-07-25* Appli très efficace pour connaître un éventuel CTOT suffisamment en amont pour anticiper ### 4/5 — Great app for handlers but a arrivals section would help *2022-12-31, version 5.2.8* Fantastic app to help handlers that shows all departures, use to show up to 12 hours before but has been cut back to 6, the 12 helped with planning. A arrival sections/filter for each airport would also help, means that we could get a rough ETA for aircraft landing rather than scrolling through the various apps. Great app, easy to use, regular updates and would recommend for any handling company. ### 4/5 — Bel outil d’information *2022-10-03* Super outil découvert récemment. Je l’utilise en ligne et l’info des slots est génial avec la carte du secteur concerné ! ### 4/5 — Excellent app *2022-10-01, version 5.2* From day to day ground ops when out on the go this app is a lifesaver. My 1 suggestion is we don’t often use ICAO airport codes, we still do but not to to any sort of excessive degree. So a filter with airport departure ctots with IATA codes would be fantastic. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
