Birthdays slip because they live in too many places: an old calendar, a social network, a note on the fridge. A birthday reminder app puts them in one list and reminds you early enough to buy a gift, not just late enough to feel bad. Describe the reminders you want, the AI agent builds the app, you test a reminder in the emulator preview, and you download the APK. The list stays on your phone.
What your birthday reminder app will have
- Upcoming — the next birthdays in order, each with a photo, the date, "in 12 days" and the age they will turn.
- Today banner — on the day, the person at the top with a Send wishes button.
- Person page — birthday, group, notes, gift ideas with a Bought checkbox, and past gifts so you never repeat one.
- Add person — name, photo, date and group, with the year optional for people who keep it quiet.
- Calendar — a month view with a dot on every birthday.
- Reminders — a week before and on the morning of the day, as local notifications.
There is no account and no server: the list, photos and notes are saved on the phone and work offline.
Features you can ask for
- Reminder times per person: a month ahead for someone who lives far away, the same morning for a colleague.
- Anniversaries and other yearly dates with their own icons.
- Message templates with the person's name filled in.
- Groups with colors and a filter on the home screen.
- A milestone badge for round birthdays, such as 18, 30 or 50.
- A gift budget note and a gift ideas list you can add to all year.
- A yearly overview showing how many birthdays fall in each month.
Ideas to make it yours
Reminders work the same way in any app, and the to-do and habit tracker guide explains how to describe repeats and times. For another take on dates that matter, the plant and pet care reminder guide uses the same local notifications for watering and vet visits.
Get it on your phone
- Press Build this birthday reminder app and sign in with Google. The agent starts building right away.
- Add a few people in the emulator preview and fire a reminder from the Simulate panel to see how it reads.
- Ask for changes in plain words: "sort by next birthday, not by name", "add a Neighbors group", "show the age in bold".
- Press Download APK and install it on your Android phone. Allow notifications when the app asks.
- To share it on Google Play, build the signed version; the APK builder page explains the steps.
After installing, add a test person whose birthday is tomorrow and set the reminder for a minute from now. Seeing it fire on your own phone is the best check there is.
Reminders that actually fire
A birthday reminder app is only as good as its notifications, so it is worth knowing how they work. The app schedules each reminder on the phone itself as a local notification. On a real Android phone it appears at the set time even when the app is closed, with no internet needed. The first time you open the app it asks for permission to send notifications; if you tap No, nothing will arrive, so ask the agent for a friendly screen that explains why before the phone's own prompt. Some phones with aggressive battery saving can delay notifications from apps you rarely open, so opening the app now and then helps. When you edit a date, the app reschedules that person's reminders automatically, and the week-ahead reminder gives you time for a card, a gift or at least a call.
Frequently asked
Will I get the reminder if the app is closed?
Yes. Reminders are local notifications, so on a real Android phone they fire at the set time even when the app is closed. In the emulator preview you trigger them from the Simulate panel to check the wording.
Can I add many birthdays at once?
Paste a list into the chat, one person per line with the name and date, and ask the agent to load it as the starting list. You can also ask for a quick-add screen that takes a name and a date in two taps.
What about people born on February 29?
Say how you want it handled, such as a reminder on February 28 in other years, and the agent builds it in.
Can the app track anniversaries too?
Yes. Ask for event types such as birthday, wedding anniversary, work anniversary or a pet's birthday, each with its own icon and reminder times.
Is my list private?
Yes. With the idea above everything stays on the phone: there is no account and nothing is uploaded. Install it with Download APK and your list never leaves your device.
