Böyle bir uygulama için abonelik sistemi de ancak bizim yerli yazılımcının fikri olabilir. Silme vakti gelmiştir. ### 5/5 — Fast and practical for travelers *2026-01-24, version 3.1.0* I’ve been using Koin for years while traveling and it’s one of the fastest and most practical apps for converting coins and currencies. It’s incredibly efficient, easy to use, and perfect when you need quick conversions on the go. Highly recommended for travelers. ### 1/5 — Para rklenmiyor *2022-09-16, version 2.0.2* Program çalışmıyor ülke para birmi eklemek istediğimde kapanıyor ### 1/5 — Güncelleme sonrası sorun *2022-08-18, version 2.0.2* Yıllardır ağız tadıyla kullandığım bu uygulama ile son güncellemede darma duman oldum. Sürekli hata veriyor. Uygulamanın son gücellemesi sonrası bütün favori para birimlerim gitti. Amerikan Doları uygulama içinde güncellemeden sonra çıkmıyor. Ayrıca para birimlerini tıklayınca favoriye eklenmeden uygulama kapanıyor. Uygulamayı sildim yeniden yükledim yine aynı hatayı veriyor. Acil yeniden güncelleme şart. Arasan kaç zaman geçti hala uygulmayı kullanamıyorum para birimini tıklayınca uygulama birden kapnıyor. Silip yüklüyorum hala aynı hatayı veriyor. Acil güncelleme ### 1/5 — Geçmiş olsun *2022-07-11, version 2.0.2* Güncellemeyle birlikte uygulama içi ücretli oldu, hayırlı olsun. Onu geçtim, bedavayken eklediğim kurlar silinmiş, şimdi TL eklemeye çalışırken uygulama çöküyor. Yani güncelleme kodunuzda, tahminimce, bir hata var ne eklediyseniz. Uygulamayı siliyorum ancak para verip kullanmak isteyenler kullansın istiyorsanız haberiniz olsun çalışmıyor. ### 1/5 — Y *2019-05-12, version 2.0.0* Eskisi daha güzel ve anlaşılanilirdi ### 5/5 — Love the new design🎉 *2018-11-16, version 2.0.0* The new design is stunning! ### 5/5 — Amazing App *2018-11-16, version 2.0.0* I recommend this app to everyone. Beautiful design and very useful app. Working perfectly smooth:) Great Job. Thanks ### 1/5 — Eski tasarım daha iyi *2018-11-16, version 2.0.0* Yeni tasarımla tam bir facia. ### 5/5 — Muhteşem *2018-08-09, version 1.1.1* Mağazada ki en iyi döviz kuru uygulaması, arayüz sade ve kullanışlı, tamamen ücretsiz ve reklam yok. Çok hızlı açılıyor. ## Frequently asked questions about Travel Currency Converter Koin ### Does Koin have ads?
