- Icons and names for points of interest and house numbers, with a place sheet - Every function works with only a touch screen (on-screen keyboard for text fields) - Small dot in the top-left corner while background work runs - Smooth drawing of a turned map once it stops moving - Browsed tiles move into a download instead of being fetched again - Downloads use one connection; tiles are prepared in idle time - Fix tiles staying coarse when memory is short - Smaller label font (39 KB instead of 80 KB) - App data in appdata/ (Tactility main, November 2026)
- Routes for walking, cycling and driving, found on the device from the downloaded maps - Route preview with walk, bike and car buttons; default mode in Settings - Turn-by-turn following: next turn and street, distance and time left, off-route recalculation, arrival - Without a GPS fix, the start is chosen on the map, at the screen centre or at an approximate position - Prepared tiles split into geometry, label and routing files: maps open and label faster - Key hints only on boards with a keyboard
- target.platforms: esp32s3 and esp32p4 - README: version 0.4.0, ESP32-P4 in the requirements

Maps 0.4.0 (beta): offline vector maps and navigation for Tactility
An offline map app for Tactility. It downloads OpenStreetMap vector tiles from OpenFreeMap by itself, stores them on the SD card and draws them on the device. It also shows your position, records tracks, imports GPX files and calculates walking, cycling and driving routes, without a connection once the map is downloaded.
This is a beta: At this point, the LilyGO T-Deck (and T-Deck Plus variant) is the only officially supported device. Although M5Stack Tab5 has been reported working. (see Known limits).
