| r/LearnJapanese | ~272,000 | Yes (limited) – Allowed only via weekly “Materials & Self-Promo Wednesday” threads. After posting there and getting positive reception, devs can request mod approval for a one-time front-page post. | Must follow the subreddit’s self-advertising process: post in Wednesday thread first, then mod-review before any standalone post. Product should genuinely help learners; kana-only apps are explicitly disallowed. |
| r/LearnKanji | ~3,300 | Yes – No explicit self-promo rule posted; relevant learning tools are generally welcome. | No formal promo policy given the small size (3k members). General Reddit self-promotion etiquette applies (be transparent and don’t spam). Ensure the content is on-topic (Kanji learning). |
| r/rhythmgames | ~45,000 | Yes – Self-promotion is allowed if occasional and on-topic. | Limit frequency: posts about your own game should be infrequent and relevant to music/rhythm gaming. Excessive or spammy promo may be removed or result in a ban. Use appropriate flair (e.g. “Mobile Rhythm Game”) when posting. |
| r/iOSGaming | ~245,000 | Yes (on Saturdays) – Developers can promote only on “Developer Saturday.” Self-promo posts are permitted during the 24-hour Saturday window. | No promo on other days (will be removed). Posts should include an App Store/TestFlight link (only iOS games). The sub marks these with a “Developer Saturday (Self-Promo)” flair. Breaking the rule (posting outside Saturday) risks an immediate ban. |
| r/languagelearning | ~3,300,000 | Yes (very strict) – Promotional/resource posts are permitted but heavily moderated. Preferably share in the weekly “Share Your Resources” sticky thread. | Strict criteria: Your app/resource must support multiple languages (they generally do not allow single-language learning tools). It must be available (released) and offer free features (no paywall just to demo). New members with no prior participation cannot post paid products. Even if allowed, limit frequency – roughly one self-promo per month (more only if previous post was very well-received). Strong focus on quality and transparency: be upfront that you’re the developer and engage with any feedback. Expect removal or banning if the post is low-quality, overly commercial, or you haven’t followed the guidelines. |
| r/MobileGaming | ~76,000 | Yes – Developers can announce new mobile games (iOS or Android). The community regularly discusses new releases, and dev posts are accepted under “New Release” flair. | No dedicated self-promo rule posted. In practice, devs often share games freely, but quality and relevance matter. The mods even run occasional “Game of the Day” events where mobile devs submit their games to be featured. As always, avoid spam and ensure your post clearly describes the game (including a link to the App Store) to engage the community. |
