Coming from another tracker or a spreadsheet? Moving takes about a minute, because most of what you have done is already in the game.
Most of your progress lives in the game, not in another site. Enter your name and Cape Tracker reads your skills, XP, quests and Adventurer’s Log from the RuneScape API, then ticks every cape requirement those already meet. From then on it takes a reading every night, so your XP history keeps building even on days you do not open it.
Enter your name →Anything the game does not report, you ticked by hand somewhere. If that was on the RuneScape Wiki, Settings takes its backup file, or names pasted straight from a wiki page, one per line. You see what will be ticked before anything changes.
Open Settings →Choose a cape and Cape Tracker lists what is still missing, roughly how long each part takes, and lets you line it up in your own order with milestones.
Choose a cape →The RuneScape API only reports where you are today, so your history here starts with your first sync and nothing earlier can be filled in. Sync on two different days and your charts start; after that a reading is taken every night, so the XP charts keep growing even on days you do not open the tracker.
Your progress is saved on the device you use, with a daily cloud backup. To carry it to a phone or another computer, use the sync link under Settings → Backup & sync. See how your data is kept.
