⭐ Prioritize & Remind
Focus on what matters most.
With A5 Journal, you can star important entries to highlight key moments, tasks, or records.
Starred entries are easy to access and help you quickly filter out the noise.View only your important entries directly from your journal page,
or see all starred entries in one place within the search section —
making it simple to stay organized and focused on what needs attention.
Reminders
Never lose track of what comes next.Set reminders directly from your entries so you don’t forget important follow-ups,
tasks, or notes for the future. When a reminder is added,
the entry is clearly marked, helping it stand out when you return to it.All reminders can be accessed through the notifications bell, where you can view upcoming, active, or past reminders —
and manage or delete them as needed.
Why this matters
A journal shouldn’t just store information — it should help you act on it.By combining prioritization and reminders, A5 Journal turns your entries into a system you can rely on —
helping you stay organized, proactive, and in control of what matters most.
Attachments + Exports
Capture what matters, exactly when it happens.
With A5 Journal, you can attach photos directly to your entries — either by taking a picture in the moment or selecting one from your library.
Each image is stored alongside the entry it belongs to, creating a clear and complete record of events.This means your notes aren’t just words — they’re supported by real visual context.
Whether it’s a site condition, an issue, or a key moment, everything is documented together, in one place, and in order.
Some moments need more than words.With A5 Journal, you can attach supporting files to your entries — giving your written record visual or documented context.Attach:
• Photos
• Screenshots
• Supporting imagesEach attachment is stored alongside the original entry and becomes part of that permanent record.No substitutions.
No silent replacements.What you attach stays attached.
Your records, ready to share — without losing integrity.
A5 Journal allows you to export your entries as JPEG, PNG, or PDF files, each with a visible watermark.
This ensures that your records remain clear, time-based, and difficult to alter without it being noticeable.Exports are designed to reflect your entries as they were originally recorded — preserving structure, timestamps, and attached images.
Whether you’re sharing documentation, keeping backups, or providing records when needed, your information stays organized and dependable.
Share responsibly. Preserve integrity.Entries can be exported as image files.Why images?Because image exports:
• Preserve the exact layout
