## Obo Reviews in Indonesia

### ***** "Keren"
Aflikasi Obo menurut saya sangat membantu untuk belajar bahasa Jepang dari dasar. Materinya dimulai dari hiragana dan katakana, kemudian lanjut ke kosakata, tata bahasa, sampai kanji, jadi cocok untuk pemula yang benar-benar ingin belajar dari awal.

Saya suka karena bisa belajar secara bertahap melalui aplikasi dan mengulang materi kapan saja. Buat yang sedang belajar bahasa Jepang secara mandiri, aplikasi ini cukup membantu untuk membangun dasar sebelum lanjut ke materi yang lebih sulit. 🇯🇵📚

-- アンッガス, 2026-04-27

### ***** "sedikit saran"
apknya bagus bgtt! membantu dalam belajar bahasa jepang. tapi aku mau kasih saran biar kalo kartu yang “masih sulit” dipelajari tuh masih dalam lingkup belajar atau siklusnya ngulang di 1 waktu yang sama (pas pake flascard kan kalo kartunya udah dipake semua biasanya ada tanda centang buat nandain selesai). nah kurleb kayak di apk anki yang ada 3 nomor berwarna (biru:baru, merah:intervar pendek, ijo:interval panjang). ini sangat membantu buat ngejar target hafalan kotoba salam sehari. semoga admin paham dan bisa ditambahkan fitur barunya😃🙏
