Start a chest log in under a minute
Open the Fortnite chest tracker and choose a session label and a mode. No account or Epic Games sign-in is required. The tracker starts at zero; it does not read your match history, connect to Fortnite, or count openings in the background.
- Choose what you are counting. Use your own openings for a personal log. If you are keeping a shared squad log, agree on who reports each opening so the same chest is not counted twice.
- Add your openings. Press +1 chest for one opening, +10 for ten, or enter a whole number in the batch field. A batch is a convenience for catching up after a match.
- Set a personal goal. Enter the total you want to reach. The progress bar compares your lifetime logged total with that goal. It is a logging milestone, with no connection to an in-game reward.
- Correct mistakes with Undo. Undo reverses recent edits in the current page session, up to 40 steps. Undo history is not saved after a reload.
Keep sessions and lifetime totals separate
The lifetime total adds together your logged openings. The session counter covers the run you are recording. New session clears the session counter and session label while keeping your lifetime total, goal, and reward checklist. Give the new run a useful label, such as “Tuesday solo” or “Squad run 2.”
Choosing Solo, Duos, Trios, or Squads is a label for your records. It does not multiply a counter or detect teammates. For example, if four players report 15 distinct openings each, enter a combined batch of 60 only when those openings belong in the same log. Entering 60 and then multiplying it by four would overcount.
Mark the rewards you actually receive
The reward checklist starts with personal tracking categories. Mark a reward as found after you observe it in Fortnite, and unmark it if you made a mistake. Add a custom reward label when your session needs a different item or category. Avoid personal information in labels.
A found mark records your observation. It does not grant an item, prove ownership, list the entire current loot pool, or synchronize with an Epic account. A category is a checklist entry, so finding a Gizmo several times still occupies one marked entry. This is different from a per-drop frequency study.
Use the odds calculator carefully
Open Drop odds, select the reported Pirate Shop Access preset or enter a custom “1 in N” rate, then set the number of eligible attempts. Use my total copies your logged count into the calculator; use it only if your log contains the chest openings to which the selected rate applies.
Leave the multiplier at 1 unless you have a source for a different rate in the mode and event you are modeling. The calculator estimates the chance of at least one result under a fixed, independent per-opening model. It cannot predict a reward or make the next chest “due.” Read the Fortnite chest drop-rate guide for the assumptions and examples.
Save, back up, and move your log
Your browser stores the tracker locally under chest-ledger-v1. It is available again in the same browser profile on the same site origin when local storage is permitted. Another browser, a private window, a different device, or a different hostname has separate storage. Browser cleanup can erase it. The storage message tells you when saving is unavailable.
- Choose Export backup to download a JSON snapshot of your current totals, settings, and checklist.
- Keep that file somewhere you control. It includes the session and custom reward labels you entered.
- On another device or before restoring, choose Import backup and select the JSON file. The tracker validates the file and asks before replacing the current log. Import replaces the current state; it does not merge two sets of openings.
The calculator inputs and undo history are not included in saved tracker state. Multiple open tabs on the same origin can detect changes to the shared local record, but this is browser-local behavior, not device synchronization.
Share a summary or clear the tracker
Share summary prepares a short text report of your count and checklist progress. Your session label and custom reward names are omitted. Depending on browser support, it opens a share sheet, copies text, or displays text for manual copying. You choose where to send it; there is no public leaderboard or automatic community upload.
Reset data asks for confirmation before removing this tracker's local record. Export a backup first if you want to retain it. Reset does not remove downloaded files or summaries already shared. See Privacy for the data-handling details.
