Well I’ve downloaded to iPhone but it is literally just a black screen on opening ### 1/5 — Just a black screen *2025-05-15, version 4.6.4* It instals and once clicking yes to allow notifications I just get a black screen with no further prompts or notifications. Looks like I’ll be doing the challenge without the app :( ### 1/5 — Useless app *2024-09-28, version 4.3.0* The app provides zero extra information than the event website - it actually only opens the website inside the app. Absolutely useless. ### 1/5 — Doesn’t work. Don’t bother. *2023-05-17, version 3.8.2* App downloads. Open and gets stuck on load screen. Don’t bother. ### 1/5 — Terrible App *2021-09-23, version 3.2.10* If i could give a “no star” rating I would. This is the worst app I’ve ever used. Just had a message to say my event has had updated details and to refresh in the app (why it can’t auto update I don’t know) Ive refreshed and the same amount of zero information is there- despite the event originally being planned for February! I don’t know how much they've paid their App developers, but they need their money back as it’s awful ! ### 1/5 — Don’t waste your time! *2021-04-17, version 2.8.1* I don’t normally write reviews, but this app is a complete waste of time, poorly developed, you can’t update or view your event details, every email they send they say download our great app! No it’s rubbish. ### 1/5 — Action Challenge Aoo *2020-08-31, version 2.8.1* I have wasted hours attempting to download this App to my mobile phone but it just doesn’t download. Why not have all the info on the web site as it used to be - that worked perfectly. This is the second year in a row I have tried to download this App without success! Totally frustrated by it ! ### 1/5 — Doesn’t work *2019-09-12, version 2.6.7* Have entered the North Downs Challenge. When I was first notified of the app I installed in and put in the code. Nothing. Thought it might be teething problems so left it. We’re 2 weeks away from the challenge and I still can’t get it to work. ### 1/5 — Awfull *2019-04-26, version 2.6.7* This app is terrible ### 5/5 — I love this app *2018-09-06, version 2.6.1* . ## Frequently asked questions about Ultra Challenge Series ### What is the Ultra Challenge Series app?
