==== 2. Why adding GPS is absolutely worth it ====

You’re not just doing this to keep the app alive — you get a ton of extra signal:
# Distance & route insights - Integrate with CLLocationManager: - Accumulate total distance - Optionally store a low-frequency “breadcrumb trail” (e.g. every 1–2 minutes) for a post-drive map. - These can feed: - “You drove 240 km today” - Per-session stats (avg speed, max speed, etc.)
# Speed validation / redundancy - Combine: - CMMotionActivity.automotive - GPS speed - Use speed thresholds to: - Ignore weird .automotive when the user is walking near a road - Detect “moving but not driving” vs “clearly driving” - You can also use speed drop + long stationary intervals to auto-pause/end sessions if the user forgets to tap Stop.
# Weather at route segments (if you want to get fancy) - If the product ever wants weather: - Grab the start location and maybe a few intermediate points - Fetch weather when online (current or historical depending on API). - Then you can show “You drove X km in rainy conditions” etc. - This fits nicely with your offline-first stance: store location points locally, only fetch weather opportunistically when online / user views history.
# POIs & “break suggestions” (future idea) - With GPS + distance + time, you can later add: - “Suggest nearby rest stops after 3.5h driving” - “Log where you took breaks”

All of that turns “we just need 4h timer” into a useful driving log, which makes your permission requests much easier to justify.
