Bom Calendar - Period tracker, from bomcomes, is an iPhone app that helps users log menstrual cycles and pregnancy progress in daily life. It pairs cycle and ovulation prediction with a built-in planner and to-do list, offering day-to-day hormone-based insights about mood, memory, and energy. The app includes Pregnancy Mode, BMI and weight logging, customizable calendar views, and PDF export for medical consultations. It targets people tracking fertility or pregnancy who prefer a single health-and-schedule workspace.

Bom Calendar combines menstrual tracking and daily planning in one daily view

The app merges traditional cycle and ovulation tracking with a schedule and to-do list, so health entries sit beside appointments and tasks. Predictions use calculation methods from the American Board of OBGYN, which the developer cites for cycle and pregnancy-window estimates. Daily hormone-based notes explain shifts in mood, memory, and physical energy, turning calendar days into actionable context for planning work, exercise, or rest.

Account integration and exporting support continuity across devices

Bom Calendar requires iOS 15.0 or later and runs on iPhone and iPad; account sign-up via email, Google, or Apple unlocks auto-backup and restoration. Users can generate professional PDF reports intended for medical consultations, and a secure sharing function lets a partner view selected calendar data. These options make switching devices or preparing for appointments straightforward if an account is used for backup.

Customization fits people who prefer tidy, personalized displays

The calendar display can be personalized with colors, icons, and visibility settings so users can mark symptoms, fertile windows, or appointments at a glance. Reviews note a clean, organized design that avoids clutter, which reduces onboarding friction for users who prefer a simple, readable layout. The app also includes weight logging and automatic BMI calculation to keep routine health metrics in the same view.

Medical-standard predictions and daily hormone notes aid practical planning

Predictions are tied to established obstetrics guidelines, which supports predictable cycle estimates and pregnancy probability windows. Pregnancy Mode supplies weekly development updates and tips, shifting the app’s tone from cycle forecasting to ongoing pregnancy reference. Daily hormone insights explain likely changes in energy and focus, so users can plan demanding tasks or rest periods with the calendar’s context in mind.

Privacy and data handling emphasize account-backed backups and controlled sharing

Data continuity depends on signing in with an email, Google, or Apple account for auto-backup and restoration, a model the app endorses for safe transfers between devices. The sharing feature lets users selectively share calendar information, and PDF export provides a portable, printable record for clinicians. The app does not claim on-device-only storage as the primary backup path; account-based backup is central to data portability.

To sum up, Bom Calendar suits routine-focused users who want context-aware health planning

To sum up, Bom Calendar is a practical choice for people who want predictive cycle context woven into daily scheduling; its medically grounded estimates and readable presentation help plan work and self-care around likely hormonal effects. Users who prefer strictly local-only backups or who use non-iOS devices should consider whether the app’s account-backed workflow and iOS requirement match their needs.
