The eStudyUniverse app is built to keep working when the connection drops, which matters when data is expensive or patchy. What you have already opened stays readable, downloaded papers and videos play from the phone, and actions you take offline are saved and sent when you reconnect. Some things still need a connection, and this page lists them honestly.
What works without a connection
| You can | Condition |
|---|---|
| Browse subject and paper lists | If you opened them recently while online |
| Read past papers | If you saved them for offline use |
| Watch video lessons | If you downloaded them |
| Play practice sets | If you loaded them while online; they are graded when you reconnect |
| Continue a timed exam | If it was started online; answers are saved and sent later |
| Reread AI Tutor conversations | Conversations you have already opened |
| Write to the AI Tutor | Your message waits and is sent when you reconnect |
What is saved and sent later
Twelve kinds of action are stored on the phone and sent automatically when the connection returns, including:
- video and lesson progress;
- answers and flags during a timed exam, and finished exam attempts;
- answers to practice sets played offline;
- messages and photos for the AI Tutor, and renamed conversations;
- daily goal ticks and profile edits.
A banner shows “Syncing” and then “Changes synced” when everything has gone through, and a thin bar tells you when the phone is offline.
What needs a connection
- AI Tutor answers (your question waits, the reply comes once you are online);
- competitions, leaderboards and anything played against other students;
- opening a list or page for the first time;
- signing in;
- searches you have not run before.
Maths formulas can look plainer offline, because the maths fonts load from the internet.
Getting ready before you go offline
- On Wi-Fi, open the subjects you plan to revise so their lists are stored.
- Save the papers you need for offline use from the paper viewer.
- Download the video lessons, choosing the smaller copy where offered to save space.
- Load a practice set or two in the subjects you will work on.
Storage
Downloads are listed under Profile, in Downloads and Bookmarks, where you can open or remove them. Up to three download at a time. Downloads stay on the phone when you sign out; they are cleared if a different account signs in on the same phone, or if you clear the app’s data.
Limits worth knowing
- Offline means “what you already loaded”. Nothing new can be fetched without a connection.
- Scores arrive later. A practice set played offline is graded when you reconnect.
- Only exam bookmarks are queued. Bookmarking a paper while offline may not be saved.
- Waiting photos take space. Photos queued for the tutor are kept on the phone until they are sent.
