⚑ Review opportunities · 4where users are leaving the leader, and what a new app could take

Three of the four qualifiers this month are TR — for an indie, that concentration is the headline, not a footnote.

TradingView: Track All Markets (UK) — 46 recent 1–2★ (46% of 100) · Top Grossing #2
  • Users hurting on: mobile bugs — charts/indicators failing to load, daily reinstalls (14, "The only way to rectify this is reinstalling the app. Which you have to do multiple times a day.") [confidence: high]; AI-only support with no human escalation for premium payers (8, "Support bot won’t connect me to agent or make a ticket even though I’m on premium.") [confidence: high]; retroactive plan limits (6, "now they want me to upgrade to a higher tier just to keep my watch lists over 100") [confidence: high]; invasive KYC to view charts (3) [confidence: med].
  • Your opening: ship a mobile-first, fast-loading charting + watchlist app with no retroactive plan limits and reachable human support, aimed at TradingView's steady (0.54) but 46%-angry UK base — you win on reliability and trust, not indicator count.

cross-checked: kept 4, cut 5 (all five "asking for and NOT getting" request items — iPad app, mobile-only layouts, bigger screeners, onboarding helpline, delete confirmation — verified verbatim but each backed by a single review, below the 2-review floor; KYC cluster downgraded to med at 3 supporting reviews)

ForInvest: Piyasa Analizi (TR) — 26 recent 1–2★ (52% of 50) · Top Grossing #4
  • Users hurting on: updates that delete watchlists and strip data columns (8, "Her güncellemede sayfam’da takip ettiğim şirketler siliniyor" — every update wipes the companies I follow) [confidence: high]; free live data revoked + upsell banners at 549 TL/mo (8, "Her şeyi paralı yaptınız, ücretsiz üyelik masal") [confidence: high]; iPhone overheating/freezing (4, "telefonumun aşırı derecede ısınmasına ve kasmasına neden oluyor") [confidence: med].
  • Your opening: a lightweight, cool-running BIST market-data app with locally-persisted watchlists and one honest price for live data takes users from a fading leader (growPotential 0.04) whose paying customers are publicly announcing their move to Matriks.

cross-checked: kept 3, cut 4 (all four request items — persistent watchlists, single-screen home, affordable real-time data, denser phone layout — verified verbatim but single-review each, below the 2-review floor; overheating cluster downgraded to med at 4 supporting reviews)

BJK SuperApp (TR) — 25 recent 1–2★ (50% of 50) · Top Grossing #7
  • Users hurting on: paid priority ticketing that collapses at the on-sale minute (13, "15 dakikadir karakartal+ ayricaligiyla bilet almak icin bekliyorum, app calismiyor") [confidence: high]; registration/password/phone-change flows broken for days (8, "3 gündür şifre yenileyeceğiz ne nfc çalışıyor ne dilekçe dönüşü yapılıyor") [confidence: high]; ID-number KYC just to read club news (2) [confidence: med].
  • Your opening: honest caveat — this incumbent is official and captive, so you can't peel its core users; the exploitable wedge is the adjacent tooling its failures create (a reliable Turkish match-ticket drop/queue-status alert app spanning Passo + club apps) while BJK's spiky, event-driven inflow (growPotential 0.99, r2 0.62) keeps generating angry ticket-day cohorts.

cross-checked: kept 3, cut 1 (the lone request item — account recovery for a dead phone number — verified verbatim but single-review, below the 2-review floor)

Gedik Trader (TR) — 69 recent 1–2★ (34% of 200) · Top Grossing #9
  • Users hurting on: outages during market hours and a delete-and-reinstall routine (15, "saatlerce süren kesintiler. Piyasa açıkken akıl alır gibi değil") [confidence: high]; a 20-years-dated UI missing per-stock % P/L (15, "Rezalet bir tasarım 20 yıl öncesine ait") [confidence: high]; dead price alerts (4, "GÜNLERDİR… ALARM UYARI GELMEMEKTEDİR…!") [confidence: med]; password prompts on every open (5) [confidence: high].
  • Asking for and NOT getting: a % profit/loss column — requested in 7 separate reviews across three years and never shipped [confidence: high]; in-app money transfer (5) [confidence: high].
  • Your opening: trading is captive to the brokerage, but the engagement layer isn't — a broker-agnostic BIST portfolio companion with % P/L everywhere and alerts that provably fire peels the daily-use surface off an incumbent whose 0.92 growth band masks a stagnant +13 ratings/mo base and three years of ignored, identical complaints.

cross-checked: kept 6, cut 2 (execution notifications and TradingView-style charts — verified verbatim but single-review each, below the 2-review floor; dead-alerts cluster downgraded to med at 4 supporting reviews)
