HabitSpark AI is available on iOS (iPhone and iPad) and Android. Your data syncs across devices via your account, so you can check your habits anywhere.

About 30 seconds. Our onboarding walks you through picking your habit categories, choosing your coaching tone, and setting your reminder time. We create your starter habits automatically — you just pick what matters to you.

Spark (free) gives you everything you need to track habits effectively — unlimited tracking, streaks, the full Stats dashboard with charts and heatmaps, all 14 badges, the social leaderboard, and local AI insights. Spark Pro (£3.99/month or £29.99/year) adds GPT-powered personalised coaching that references your actual data, per-habit coaching tips, AI-generated habit suggestions, and adaptive tone messaging. You can try Pro features for free and upgrade anytime. Compare plans.

The AI Coach works in two layers. First, a local analytics engine crunches your habit data on-device — identifying your strongest days, weakest patterns, streak health, and momentum. This powers the AI Coach card on the home screen for all users, completely free. Spark Pro subscribers unlock the second layer: your analytics summary is sent to GPT-4o for deeply personalised coaching, per-habit tips, and habit suggestions that reference your actual data — like "You're strongest on Tuesdays at 92%."

Yes! During onboarding (or anytime in Settings), you can choose between three tones: Gentle (compassionate and understanding), Motivational (energetic and action-driven), or Neutral (calm and data-focused). The AI adapts all its messages to match your preference.

The AI looks at what you already track and identifies gaps. If you have fitness and nutrition habits but nothing for mindfulness, it might suggest "15-min Evening Journal" and explain why it complements your routine. Suggestions are specific (not just "Exercise") and always include a reason tied to your data.

A streak counts consecutive days you've completed a habit. Tap the spark button each day to keep it going. If you miss a day, the streak resets — but the AI Coach will encourage you to bounce back rather than give up. Your longest streak is always saved, and you'll earn badges at 3, 7, 14, 21, 30, and 60 day milestones.

The Stats tab includes a weekly trend chart (9 weeks), a day-of-week radial showing your strongest and weakest days, a 28-day heatmap, per-habit performance bars with completion rates, a category distribution view, and an AI-generated insight. The home screen also shows a momentum score (0–100) and a "Your Rhythm" day-strength chart.

There are 14 badges across three categories. Streak badges (First Flame at 3 days through Eternal Flame at 60 days), Completion badges (Getting Started at 10 sparks through Unstoppable at 500), and Special badges (Perfect Week, Comeback Kid, Habit Collector). Each badge shows a progress ring so you can see exactly how close you are.

Connect with friends and you'll see a ranked leaderboard based on total habit completions. The top 3 get a podium display with medals. You can see everyone's streak, today's sparks, and earned badges. Tap any friend to expand their card and send a Challenge or Celebration.

Absolutely. Social features can be turned on or off in Settings. When disabled, the Leaderboard tab is hidden from the navigation bar entirely. HabitSpark works perfectly as a solo experience — the social layer is there if you want it, but never forced.

Yes. Your habit data is stored securely in Firebase with authentication. The AI Coach only receives a compact statistical summary of your patterns (completion rates, streak lengths, day-of-week trends) — never your raw personal data. Analytics are calculated locally on your device first, keeping things fast and private.

Your data is synced to the cloud via Firebase. Sign in on a new device with the same account and all your habits, streaks, completion history, and badges will be right where you left them.
