### 5/5 — Awesome!!!

*2026-08-01*

The developers of this program are so responsive.  I asked for certain modifications to help the program work for me.  The features were added right away and the developer reached out to me to walk me through the changes.  This program syncs perfectly with the apple calendar.  All you have to do is set an alert for your event within your calendar and CalSyncAlert sets an alarm that does not turn off until you manually turn it off. I will no longer miss important events!  Thank you so much!

**Developer response:** Thank you so much — this genuinely made my day. Being able to add the changes you needed and walk you through them is exactly why I built CalSyncAlert. So glad it's helping you never miss an event, and I'm always around if anything else comes up. 🙏

### 1/5 — Has some core problems

*2026-05-06*

Doesn’t do or have an option to do full screen alerts for before the event only the start time. Mine doesn’t output sound, so overall not helpful for my needs

**Developer response:** Following up on our earlier reply — version 1.8 is now live on the App Store. It lets you set a custom advance notification time for each event, so you can get a full-screen alert before an event begins, not just at the start time. This directly addresses the pre-event alert issue you raised.

If the sound still doesn't play after updating, it's usually a system setting — please check that the Ring/Silent switch isn't set to Silent, Focus/Do Not Disturb is off, and Settings > Notifications > CalSyncAlert > Sounds is enabled. If it still happens, please reach out via the support link in the app and we'll investigate.

We'd really appreciate it if you'd give 1.8 a try. Thanks again for helping us improve CalSyncAlert.

## Version history (last 5 releases)

### 1.15 — 2026-08-17

v1.15 — Fixes for alarm cancellation and notifications.

• Fixed alarms still ringing for an event you had already deleted.
• Fixed "Dismiss" on a notification also removing the same event's other alerts.
• Fixed the snooze duration setting being ignored, so snooze was always 5 minutes.
• Fixed notifications arriving up to a minute earlier than the set time.
• Fixed a next alarm being scheduled after you turned alarms off.
• Reworked widget refresh so the display stays more consistent.
• The Shortcuts action name now appears in your own language.

Thank you for using CalSync Alert.

### 1.14 — 2026-07-29

v1.14 — Several fixes so your alarms fire reliably.

• Fixed alarms continuing to ring for a calendar after you deselected it.
• Fixed alarms keeping their old time after you changed the alert timing.
• Fixed some notifications not being scheduled when you have many events.
• Permission prompts and VoiceOver labels now appear in your own language.

Thank you for using CalSync Alert.

### 1.13 — 2026-07-02

v1.13 — Use your Calendar's own alert timings, per-calendar.

• New "Follow each event's alerts" mode: for any calendar, CalSyncAlert can now use the alert times you set on each event in your Calendar app — so dentist appointments can alert a day ahead while daily standups alert 15 minutes before, all straight from your Calendar.
• Any alert time works: even values that aren't a preset (like "10 minutes before") are honored exactly.
• The redesigned settings sheet stays open while you toggle multiple alert times.

Thank you for using CalSyncAlert!

### 1.12 — 2026-06-25

v1.12 — Multiple alarms per event, redesigned list view and widget.

• Set multiple alarms for the same event (e.g. 1 day before + 15 minutes before). Each alarm fires independently.
• "Upcoming Alarms" list redesigned: alarms are now grouped by the day they fire, with the alarm time shown prominently alongside the event time.
• Skip is now per-alarm: silence one alarm while keeping the others.
• Widget redesigned to prominently show the next alarm time with a Today/Tomorrow tag and countdown.
• All times now displayed in 24-hour format for consistency.

Thank you for using CalSyncAlert!

### 1.11 — 2026-06-24

v1.11 — Day-ahead reminders and an easier-to-tap calendar list.

• Per-event alert timing now includes "1 day before" and "2 days before", so you can be reminded a day or two ahead — perfect for appointments, deadlines, and birthdays.
• In Settings, each calendar row now has a clear bordered card, and the per-calendar timing button is larger and easier to tap — so you won't accidentally deselect a calendar when changing its alert timing.

Thank you for using CalSyncAlert!
