HiDay
Voice Diary
Free · In‑App Purchases
HiDay opens each day with a fresh greeting and keeps your voice or text entries together with the weather of the
moment — privately, with no developer servers anywhere in the loop.
▷ A different greeting, every day
· Weather is captured with each entry (powered by Apple WeatherKit on iPhone, iPad, and Mac for accurate local data)
· Add your own background photos — applied instantly. Tap a thumbnail to switch, long-press to delete
· Soft card tone keeps your text readable even over rich photo backgrounds
▷ Security is the default
Every entry lives only in an encrypted on-device database (SQLCipher · AES-256). No developer server exists; no
accounts, no logins, no telemetry, no ad SDKs.
▷ Sync only through your own iCloud (optional)
Sync between iOS, iPadOS and macOS via your own iCloud Private Database. With one option on, the body itself is
encrypted again before it leaves the device — only ciphertext reaches the cloud.
▷ App lock
Lock the app behind Face ID, Touch ID, fingerprint, or your device PIN. The app re-authenticates every time it comes
back from background.
▷ Photo backgrounds + glass UI
7 bundled landscape photos rotate each launch. You can add your own. A frosted glass card floats over the photo for a
hand-set, paper-like feel.
▷ Pro (1-month free trial)
Bring your own Gemini key (BYOK) and unlock Old Friend mode (a one-line check-in informed by your past entries), AI
insights, AI voice, and random recall stories. The first month is free for everyone; after that it is $4.99 / year.
▷ Your data is yours
Delete the app and everything goes with it — entries, metadata, BYOK keys. Manual JSON export / import is built in so
you can leave with your own data at any time.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Small reasons to come back every day.
• A moon that fills with each day you write this month.
• A soft chime and gentle tap when you save — the day is sealed.
• An evening nudge that learns your usual writing time, with today's weather.
• Last month gathered into one keepsake page.
• Easier reading: larger text, roomier lines, a soft tint of that day's weather.
Fixed: the weather cloud no longer covers your words while writing; prices no longer stick on "loading"; Settings now shows why an AI line didn't appear.
