I Will Be

Read full description

IWillBe is a daily affirmation practice built around one simple question: Who are you becoming? You write a single identity anchor - "I'm becoming the calm parent" or "the writer who shows up" - and the rest of the app personalizes around it. Affirmations call you by name. Practice sessions are framed by who you're becoming. Every meaningful action counts as a vote toward that identity. WHAT'S INSIDE β€’ Daily affirmation feed with 5 personalized cards each morning β€’ Personalized AI affirmations generated from your identity statement β€’ Practice mode with optional narration in a calm, natural voice β€’ Home Screen and Lock Screen widgets that show your identity anchor and vote count β€’ Solid, gradient, photo, and video themes β€’ Streak counter (streak is consistency; votes are commitment) β€’ Favorites, history, and custom collections β€’ Share affirmations as image cards PREMIUM ($47.99/year, 3-day free trial) β€’ Unlimited custom affirmations β€’ Premium photo and video themes β€’ AI affirmation regeneration β€’ Ad-free forever PRIVACY β€’ Your identity statement and answers stay on-device unless you use AI generation β€’ AI generation sends your identity statement, optional first name, pronouns, and topic preferences to our server and Anthropic; it does not send your email, contacts, or precise location β€’ PostHog provides pseudonymous product analytics with no named profile and no cross-app tracking Privacy policy: https://iwillbe.illustrious.dev/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Calfmaxx

Calfmaxx turns calf raises into a real training system. Calfmaxx requires a paid subscription. A free trial is available; after the trial, all features require an active Calfmaxx Pro subscription. Most people skip calves or do them with terrible form. Calfmaxx fixes both. Prop up your phone, step into side view, and the camera counts every valid raise β€” full range only. No cheating. No guessing. Rep counting runs entirely on your device. Your camera feed is analysed in real time and immediately discarded β€” nothing is recorded, saved, or uploaded, and no video ever leaves your phone. What you get with Calfmaxx Pro (subscription required): β€’ Automatic on-device rep counting with form feedback β€’ Daily ranked challenge (60-Second Burnout) with Today, This Week and This Month leaderboards β€’ Weekly boss fights that carry damage across sessions β€’ Soleus and single-leg variations β€’ Streaks, ranks, and a transparent Calf Score β€’ Simple β€œStart Raise” sessions for everyday volume Your Calf Score combines your best Burnout, training consistency, and lifetime volume so you can see real progress β€” not just vanity metrics. Whether you’re trying to fix skinny calves, build diamond shape, or finally stop neglecting your lower legs, Calfmaxx makes the work measurable and addictive. No equipment needed. Just you, your phone, and honest raises. SUBSCRIPTION Calfmaxx Pro is required to use the app and is available as a weekly or annual auto-renewing subscription.
