Share when you are free, without showing what you are doing. Alto Calendar builds one Busy/Free calendar out of the calendars you already keep. It carries only the blocks: when you are busy, and when you are not. No titles, no locations, no guests, no notes. Then you share that one calendar with your partner, your family or a friend, using Apple's own calendar sharing. They see when you are free. They never see what you were doing. They can make one too, so you can both see when everyone is actually free. - one Busy/Free calendar, built from any calendars you pick - event details never leave your device: only the blocks are shared - see today and tomorrow as a summary or a timeline, with everyone's blocks merged - declined invitations and anything marked free are ignored, so you are not shown as busy when you are not - all-day events are ignored by default, and you can turn that on - refreshes in the background as your calendars change - ask Siri “When is Sarah free?”, or check from Spotlight and Control Center - invite from Contacts; the person you invite is shown how to share back - no account, no sign-up, no server. Your calendars stay in iCloud, where they already are Free to share with one person. Alto Calendar Pro, one purchase, shows everyone who shares with you and counts down on the Lock Screen.

In the Myers-Briggs Type Indicator (MBTI), the perceiving (P) personality type is flexible, open to new experiences, and adaptable. People with a perceiving personality type tend to have a lot of spontaneous ideas and impulses. They might act on them without rational analysis, leading to distractions and a scattered focus. 「IdeasTick」 helps you build a “slow system” by creating an objective “repetition judgment mechanism” that allows those fleeting ideas to settle. Over time, impulsive thoughts are verified and transformed into rational decisions. Core Features: - Unlimited Events Tracking - Automatic iCloud Backup - Home Screen Quick Addition Use Cases: - Feeling tired of the repetitive nature of your job and considering quitting every month? Record it and visualize how strong your desire to leave is. - Wondering if a professional training course is worth your time? Record it, and once the “certification thought” reaches 10, take action. - Have an idea for a side business but want to hold off on acting immediately? Record it, and once the count hits 10, analyze its feasibility. - Trying to quit smoking gradually? Track your weekly cigarette count and visualize your progress with helpful feedback. 「IdeasTick」 is perfect for situations when your ideas start accumulating. When the thoughts start counting, life is much easier. Product Advantages: • Anti-fragmentation Management: Turns scattered thoughts into a visual decision-making tool. • Lower Trial-and-Error Costs: Filters out 90% of impulsive ideas through time and reflection. • Data Privacy: Your thoughts are exclusively yours, stored locally on your device and iCloud, ensuring your privacy.
