Desktop Contact Manager App with Groups and Birthday Reminders

A desktop contact manager app with groups and birthday reminders is a single-user desktop application that stores names, phone numbers, email addresses, birthdays and notes in one searchable place, organises contacts into groups such as Family, Work, Friends and College, and lists upcoming birthdays inside a configurable reminder window. Most people still keep contacts scattered across a phone address book, old notebooks, email signatures and chat histories, so finding the right number means searching several places, and birthdays are remembered only when someone else posts about them. A dedicated desktop manager removes that scatter: every contact lives in one local database, groups keep personal and professional circles separate, instant search matches names, numbers and companies, and the birthday panel counts down the days to each upcoming birthday so greetings are planned instead of missed. The result is a practical desktop utility that demonstrates GUI design, local database operations, search, sorting and date arithmetic in one complete, explainable build.

This is a built-to-order software project: the desktop application source code, local database schema, demo build, project report, presentation and viva preparation material are prepared fresh for you.

Comparison

Builder note (from the actual demo build): the birthday panel sorts by days-until-birthday rather than by calendar date, so a birthday 3 days away outranks one 300 days away. Calendar sorting buried the nearest birthday at the bottom of the list during the demo build, which is why the countdown ordering was chosen.

End to end, the Desktop Contact Manager App with Groups and Birthday Reminders works as a loop from typed input to stored record to visible result. The user enters a contact through the add-contact form or imports a CSV file, and each record is validated — a name is required, and phone and email formats are checked — before it is written to the local SQLite database with its group label and birthday. When the user searches, the app runs one text query across the name, phone, email and company fields and returns matching rows ordered by name; when the birthday panel opens, it compares every stored birthday against today's date, computes the days remaining with past birthdays rolled to next year, and sorts the ones inside the 30-day window soonest first. Editing or deleting a contact updates or removes the same database row, and CSV export writes the table back out in the same layout it imports.

1. The user adds a contact through the form (name, phone, email, birthday, group, company note) or imports a CSV file; validation checks that a name is present and that phone and email formats look correct.
2. The validated record is written to the local SQLite database with its group label and birthday stored as fields on the same row.
3. The contact list renders from the database, filtered by the sidebar group or showing all contacts, and clicking a row opens the detail pane for that contact.
4. Typing in the search box runs one text query across the name, phone, email and company-note fields and refreshes the list to matching rows ordered by name.
5. Opening the birthday panel compares every stored birthday with today's date, computes days remaining with past birthdays rolled to next year, and lists the birthdays inside the 30-day window soonest first.
6. Editing a contact updates the same database row and deleting removes it; starring toggles a favourite flag that the Favourites view collects across groups.
7. Export writes the current contact table to a CSV file in the same 5-column layout used for import, so the data round-trips without loss.

Contact grouping, instant search, birthday reminders and CSV portability are the four capabilities that define the Desktop Contact Manager App with Groups and Birthday Reminders. Grouping keeps Family, Work, Friends and College contacts separate while still searchable together, so one list serves personal and professional life without mixing them. Instant search matches a typed fragment against names, phone numbers, email addresses and company notes in the same pass, so the right contact appears after a few keystrokes instead of a scroll through hundreds of entries. Birthday reminders turn a stored date into a countdown: the panel sorts upcoming birthdays by days remaining within a 30-day window, so the soonest birthday always appears first whatever the calendar month. CSV import and export complete the set, letting contacts move in from a spreadsheet and out to any other tool without retyping, which is what makes the app genuinely usable rather than a classroom exercise.

• [Contact groups] Every contact belongs to one group — Family, Work, Friends or College in the demo build — and the sidebar filters the list to that group in one click, while All Contacts still searches across every group.
• [Instant search] A single search box matches the typed text against names, phone numbers, email addresses and company notes at once, so a fragment of any field is enough to find the contact.
• [Birthday reminder panel] The panel compares every stored birthday with today's date, rolls birthdays already passed this year forward to next year, and lists the ones inside the 30-day window soonest first, with the days remaining shown for each.
• [CSV import and export] Contacts import from a CSV file with Name, Phone, Email, Birthday and Group columns, and export back out in the same layout, so the whole address book moves between tools without retyping.
• [Add, edit and delete contacts] The add-contact form validates each record before saving — a name is required and phone and email formats are checked — and any contact can be edited or deleted from its detail view.
• [Favourites] Any contact can be starred, and the Favourites view collects starred contacts across all groups for the handful of people called most often.
• [Local SQLite storage] All contacts live in a single local SQLite database file on the user's machine, so the app works with no account, no server and no internet connection.

Optional customization (not in the base build): cloud sync across devices, multi-user login, an SMS or email greeting sender, and a mobile companion app. Future scope: duplicate detection and merge, contact photo attachments, and recurring event reminders beyond birthdays.
