Where the next app actually wins.

Decade-long Navionics loyalists who are publicly posting exit notices over the $49.99/yr hike and the "subscription loop" lockout switch the week their renewal bills — they have already named the price ("Charge 9.99 a month") and the escape app (Orca, "free") in their own reviews, so conversion is a one-tap, offline, no-login navigator with an anchor alarm.

Offroaders bouncing off onX's "survey → hard paywall → surprise charge" funnel adopt a browse-everything-free trail map with App-Store-managed billing — onX's entire 1★ volume is self-inflicted funnel abuse (payers are enthusiastic), so a real free tier converts the exact people onX repels at the door.

UK and Med motorboaters locked out at sea by Navionics' login + subscription loop, and billed "4 subscriptions of £40" for charts that used to be one, switch to a fully-offline no-login navigator with a single all-region price — and unlike the US, the UK storefront is where Navionics is already fading, so the base is leaving with or without you.

UK multi-drop couriers stuck with Delm8 — an app whose users have logged 23 unmet feature requests while a fifth of recent reviewers rate it 1–2★ — switch to a faster optimizer that ships the backlog they're already writing, and the Navigation entry wall in the UK is only ~14,104 ratings, so the chart admits a newcomer.

Realtors, foresters and timber cutters paying $99/yr for LandGlide defect the moment a rival shows a per-county "data last updated" date and undercuts to ~$30/yr — the stale-data and black-screen complaint clusters have run unfixed for two years, so the trust is already gone, only the alternative is missing.

US drivers already paying MapXplorer $14.99/week for "3D live map + radar alerts + CarPlay" that doesn't work switch to a $2–3/mo app that actually ships the trio — this is a pre-validated, refund-seeking funnel, not a cold market.

TR EV drivers juggling single-network operator apps rated 1.30–1.68★ adopt one cross-network finder with live availability, broken-charger reports and lira-per-kWh — EV charging is the fastest-accelerating lane in TR Navigation and the chart is wide open (churn 11.3/week, the highest of the three markets).

İstanbul/Bursa riders who literally miss the bus because of Moovit's interstitial ad, then get told a bus is "1 dakika" away for 37 minutes, switch to a TR-first, zero-interstitial planner wired to municipal feeds — 62% recent negativity at a #3 grosser, in a market where the entry wall is only ~1,614 ratings and local-language rivals are absent.

Sailors who love Savvy Navvy but abandon over 90%-complete offline downloads, auto-renew-after-cancel charges, and £89 annual-only pricing switch to a passage planner with true offline mode and a seasonal/monthly plan — this is the best-loved marine app in the cell (126×5★) that has simply stalled on billing trust, so the affection is real and portable.
