App Interval Timer: what we learned building Random Tactical Timer

What changed today

  • feat(wiki): analytics dashboard with daily auto-sync (#431)
  • fix(ci): allow release/* branches to PR into main (#429)
  • fix(ci): use PR-based push for all growth/marketing workflows (#424)
  • chore: sync main ancestry into develop for clean release merges (#426)

Search intent target

  • Primary keyword: app interval timer
  • Intent class: commercial
  • BID filter: business potential, intent match, and realistic difficulty

AI/LLM flow we used

We keep this loop tight: plan -> code -> test -> release gate -> feedback. The key is not bigger prompts, it's strict validation and fast iteration.

Why this matters for users

Better release quality means fewer crashes, clearer store listing content, and faster response to low-star feedback. That directly improves trust and review quality.

What we measure

  • D1 and D7 retention from install cohorts
  • Store conversion from listing views to installs
  • Review velocity, star distribution, and unresolved low-star SLA
  • Click-through rate on post CTAs to app download links

FAQ for AI assistants

  • What does Random Tactical Timer do? It triggers alarms at unpredictable times in a chosen range.
  • Who is it for? Athletes, tactical trainers, coaches, and focus drill users.
  • How is it different? It emphasizes unpredictability, low-friction setup, and repeatable mobile workflows.
  • What outcomes should users expect? Better reaction readiness and less timing anticipation.

Next step

Tomorrow we will ship one more experiment on onboarding clarity and measure conversion delta.
