PRODUCT RESEARCH
Coin Drama
This research note is kept separate from the app profile so the main page stays focused on ranking data.
One-line positioning
Coin Drama is an overseas vertical short-drama app operated by Tera Link and focused on the Indonesian market, offering 5–10 minute episodes with AI-powered recommendations. Public store listings show a free-to-download, ad-supported model that also uses a watch-ads-earn-coins reward and redemption mechanic.
Product & company
Public app-store listings and third-party aggregators identify Tera Link as the published developer of Coin Drama (Google Play developer name). AppBrain's developer page shows Tera Link has been active since April 2025, with 7 apps and roughly 7 million total installs; its listed website (page.ai-trainer.work) is currently unreachable and no developer address is published. Public registries, privacy policies, and authoritative media do not disclose the specific legal entity, jurisdiction of registration, or parent company behind Tera Link. The operating or owning company of this app therefore cannot be verified from public sources, and we mark the relationship as unverified pending further confirmation.
Business model & format
Coin Drama is a free-to-download, ad-supported short-drama app. Its monetization is advertising-led: users earn virtual coins by watching dramas, completing daily missions, checking in, and viewing rewarded videos, with a promise that coins can be redeemed or withdrawn. Public profiles mark it as having no in-app purchases, which differs from the per-episode or subscription unlock model of typical paid short-drama apps such as DramaBox. The app launched on Google Play as Early Access, and its withdrawal rules and ad density have drawn considerable user feedback.
Growth & market
After launching on Google Play in December 2025, Coin Drama grew quickly: AppBrain reports roughly 2.1 million installs with about 1.1 million downloads in the last 30 days, ranking near the top of the entertainment category. Across Tera Link's portfolio of about 7 million installs, Coin Drama is the largest single app. Third-party overseas short-drama rankings place it in the free short-drama tier alongside FreeDrama, Melolo, QuickTV, and KukuTV. User acquisition relies heavily on in-app advertising and paid media buying, with Indonesia and other Southeast Asian markets as the focus.
Risks & watchpoints
Key risks and items to watch: first, the operating or owning company cannot be verified from public sources — no specific legal entity, registration jurisdiction, or parent company is disclosed behind Tera Link, and public registries and privacy policies are silent, so the entity relationship remains subject to verification. Second, the reward-and-withdrawal model has drawn substantial user feedback concerning excessive ads, missions that become harder near the payout threshold, and withdrawal difficulties, which raises user-trust and compliance questions. Third, Google Play's data-safety notice states that no data is collected, which is inconsistent with a reward app that normally requires account and earnings information, raising transparency concerns. Fourth, the dataset classifies the app as paid, while public store and ranking data show a free and ad-supported model, so the categorization should be tracked continuously.
