Tracepedia holds three encyclopedias: WildTrace (200 wild animals), AviTrace (200 birds) and StarTrace (100 constellations) — 500 entries in total. Pick one from the home screen and tap any entry to read it.
Open the comparison view and choose two entries to see their figures side by side — speed, size, weight and the rest, lined up so the difference is obvious.
Quizzes are built from the entries you can read. Answer as many as you like; there is no timer and nothing to lose by getting one wrong.
You can attach your own note to any entry. Notes stay on your device and are never uploaded.
153 of the 500 entries are free to read. Full Access is a one-time purchase that unlocks the remaining 347, and it also covers encyclopedias added in future updates.
Full Access is tied to your Apple ID. On a new device, open the Full Access screen and tap Restore Purchases.
No. There is no account and nothing is uploaded. Your notes, quiz results and collection progress live on this device only, so deleting the app deletes them.
The app interface is available in 17 languages. Entry text is currently translated into English, Japanese and several others; where a translation is not ready yet, the English text is shown.
