Very disappointed! ### 2/5 — It takes FOREVEr *2024-04-08* Takes forever to download .It says 3 min then it says 8 min. FIX IT. ### 1/5 — Audio Did Not Work *2024-04-08* Had to reset audio for the end of the totality to be alerted. Beginning of eclipse, totality and max totality did not work. ### 3/5 — Nice app but… *2024-03-02* The developer has forgotten landscape mode for us that have an iPad sitting in a Smart Keyboard. Which makes it very awkward to use the app without removing/installing the keyboard every time. Most developers forget about users that prefer and use landscape mode. ### 5/5 — “Out of this world!” (but not our solar system) *2023-10-14* Nine Cents en Beats 1 en New Phone sumisión envías Walker Janeth como tú ### 5/5 — Informative and fun *2023-10-08* This app makes it easy to track the upcoming eclipse from any location, and provides interesting graphics to show what is actually happening. ## Frequently asked questions about One Eclipse ### What does the One Eclipse app do?
