Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Self-promotion occurs frequently but is safest when framed as a story/lesson or posted in dedicated promo threads — consider checking with mods if unsure.
Links
The rules clearly allow links. A plain-text mention still often outperforms a URL from a young account.
What this community rewards
Dominant post formats: showcase, story, discussion
Write first-person, medium-length posts (a few short paragraphs). Lead with a milestone, metric, or a direct question; include concrete numbers/screenshots and a short lesson. Tone: candid, humble, and slightly celebratory. Posts that read like a story with learnings or a clear ask (feedback, users, tips) get upvoted; blatant one-line ads or link-only posts risk backlash.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked September 2026. Rules change and moderators have the final say: verify at r/appbuilding's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
