Ranked list
The 6 best anniversary reminder apps in 2026 — and the free way to do it without one
Anniversaries are the underrated special case. For birthdays, iPhone and Android ship an automatic answer: put the date on the contact and the Birthdays calendar does the rest. For your wedding anniversary, the day you got together, the anniversary of a parent's death, or fifteen years of a friendship, no such automatism exists. Apple's Contacts app does have an "anniversary" date label, but unlike a birthday it does not flow into the calendar on its own. So anyone assuming the phone will simply speak up gets blindsided on exactly the dates where forgetting costs the most. This list ranks six ways to fix that — from a free open-source app, through the built-in trick of a yearly repeating event, to apps that attach the anniversary to context rather than just a ping. Prices and features were checked against publicly available sources in August 2026; where vendors bill differently by region, we say so instead of pretending there's one number.
How we ranked — and our bias
Full disclosure: Endearist is our own product, and this page says plainly that a repeating calendar event covers the bare ping for free. We ranked by what makes anniversaries different from birthdays: lead time (an anniversary usually needs planning, not just a message), event types beyond birthdays, context about the person, and platform coverage — weighed against price and setup effort. The free built-ins compete as regular entries. All details were checked against publicly available sources in August 2026. App-store prices move by region and promotion, so check the current price before you commit. No affiliate links, no paid placements; every entry names at least one real drawback.

Endearist
Our product · not releasedAnniversaries on the person, not in the calendar — with the context that makes the message personal
Best for: People who want to say more on the day than "happy anniversary"
Strengths
- Important dates live on the contact — right beside notes, journal entries, and your reach-out cadence for that person
- Any occasion, not just birthdays: wedding day, the day you met, a death anniversary, a work milestone — with no custom-field workarounds
- The relationship journal turns the date into a story: what happened last year, what you last talked about
- Local-first on iOS, Android, macOS, Windows, and Linux, with optional E2E-encrypted sync
Weaknesses
- Clearly overkill if you're tracking exactly one anniversary a year — a repeating calendar event handles that
- The free tier caps at 25 contacts
- No home-screen widget yet — reminders surface via the app and push, not a widget like Birday's
Pricing: Free up to 25 contacts. Pro Lifetime €69 once, Pro Cloud Light €4.99/mo (€49.99/yr), Pro Cloud €9.99/mo (€99.99/yr).
If all you want is to not forget your wedding anniversary, scroll to rank 3 and create a yearly event — that's free and it works. Endearist wins this list for the case beyond that: anniversaries almost always involve several people at once (a partner, parents, long friendships), and that's exactly where a bare list of dates turns into an obligation. When the date sits next to last year's notes, you don't write "happy anniversary" — you write something that shows you remember.

Birday
Open-source Android app that explicitly handles anniversaries — not just birthdays
Best for: Android users who want lead time and privacy without paying for either
Strengths
- Explicitly supports several event types: birthdays, anniversaries, name days, and death anniversaries — precisely the gap the built-ins leave
- Any number of advance notifications, configurable to any number of days ahead — the point where anniversaries differ from birthdays
- Open source and ad-free on F-Droid and the Play Store, with no account and no forced cloud; imports from contacts or calendar
- CSV or JSON backup plus a note field per entry — your data stays portable
Weaknesses
- Android only — no iOS version, no desktop, no sync between devices
- Deliberately limited to reminding: the note field is a note field, not a relationship layer
Pricing: Free and open source (F-Droid / Play Store), with no in-app purchases.
On Android this is the best free answer on the list, and more clearly so than it was for birthdays: because Birday treats anniversaries, name days, and death anniversaries as first-class event types, it solves exactly the problem Apple's and Google's automation skips. Add configurable lead time, no account, and no tracking. iPhone owners should read on — for everyone else, the question of whether to pay for an anniversary app is now answered.

Apple Calendar + Contacts
The free built-in route: a yearly repeating event with an advance alert
Best for: Apple users with a handful of anniversaries who want to install nothing
Strengths
- Free and already there: create the event, set repeat to yearly, set the alert to a week or two before — done
- Two alerts per event are possible — one with lead time for planning, one on the day itself
- Syncs via iCloud across all Apple devices, with no third party and no extra account
Weaknesses
- The "anniversary" field in Contacts won't save you here: unlike a birthday it does not flow into the calendar automatically — you create the event by hand
- No context: the event knows something is happening today, but nothing about what it means
- Scales poorly — twenty anniversaries means twenty hand-made events, each maintained separately
Pricing: Free — pre-installed on every iPhone, iPad, and Mac.
For one to five anniversaries this is the honest answer, and it costs nothing. The one thing to know is the trap: plenty of people dutifully fill in the anniversary field on the contact card and then wonder why no reminder ever arrives — that field is documentation, nothing more. The route that works is a calendar event repeating yearly with an alert one to two weeks ahead, because unlike a birthday, an anniversary nearly always needs planning.
-
Google Calendar
The same built-in route on Android, web, and iPhone — with a Google account
Best for: Android and Google-account users who want reminders across platforms
Strengths
- Free with any Google account: create the event, repeat it yearly, set a notification with lead time
- Works wherever your account is — Android, web, iPhone, and desktop browsers, with no separate app purchases
- Multiple notifications per event, both weeks ahead and on the day itself
Weaknesses
- As with Apple: no automation for anniversaries, every event is manual work
- No context and no weighting — your wedding anniversary looks like a dentist appointment
- Everything lives in Google's cloud; to avoid that, use Birday or Endearist
Pricing: Free with any Google account.
The Google counterpart to rank 3, recommended just as honestly. Its edge over Apple is platform independence: the same event reaches you on an Android phone, in a browser at work, and on an iPhone. The limits are identical — manual work per date, no context, no grading by importance. For a manageable number of anniversaries it's still the most sensible free option.

Cardhop
An Apple contacts app with birthday and anniversary notifications built in
Best for: Apple users who want a better address book anyway
Strengths
- Anniversary notifications are built in — it's the one Apple app here that doesn't treat anniversaries as manual work
- Works on your existing accounts (iCloud, Google, Exchange): Flexibits runs no contact cloud of its own
- Strong widgets and natural-language input — useful if you're in your address book daily
Weaknesses
- For anniversary reminders alone the subscription isn't worth it — a repeating calendar event does the same for free
- Apple platforms only: no Android, no Windows, no web app
Pricing: Free basics. Flexibits Premium ~$4.75/mo billed annually (~$57/yr), bundled with Fantastical.
As with birthdays: nobody should subscribe to Cardhop for anniversaries alone — the free calendar event at rank 3 does the same job. The difference is that here Cardhop does something Apple's built-ins genuinely can't, namely surface anniversaries automatically. If you want the best address book in the Apple world anyway, that capability arrives as part of a bundle the Fantastical pairing makes reasonable.

Cupla
A shared couples calendar with countdowns to the anniversary — visible to both of you
Best for: Couples who want the anniversary on both people's radar
Strengths
- Countdowns to key dates like anniversaries are a core feature, not a by-product of a calendar event
- Both partners see the same thing — which fixes the most common reason anniversaries get missed: one person wrote it down, the other didn't
- Pulls existing Google, Apple, and Outlook calendars into one shared view, plus shared task lists for the planning
Weaknesses
- Built for couples only — the wrong tool for anniversaries among family and friends
- The free version limits how far ahead you can look, which stings on a year-long countdown specifically; the full feature set is paid
- iOS and Android only, no desktop app
Pricing: Free tier with a limited look-ahead window; Premium is a subscription (monthly or yearly, app-store price varies by region), with a 14-day trial.
The special case for a specific problem: if your anniversary goes wrong because one of you is holding it in their head and the other isn't, a shared calendar with a countdown fixes more than any reminder app on a single device. That's exactly what Cupla is built for, shared planning list included. For anything outside the couple — parents, friends, old colleagues — you'll want something else from this list.
Frequently asked questions
- Why doesn't my iPhone remind me about anniversaries?
- Because only birthdays flow automatically from Contacts into the calendar. The "anniversary" field on a contact card is documentation and triggers no notification. To actually get reminded, create a calendar event that repeats yearly and set the alert to one or two weeks ahead — or use an app like Cardhop, which surfaces anniversaries on its own.
- What is the best free anniversary reminder app?
- On Android: Birday. It treats anniversaries, name days, and death anniversaries as distinct event types, is open source and ad-free, needs no account, and allows any number of advance notifications. On iPhone there's no comparable free equivalent — there, a yearly repeating calendar event is the best free answer.
- How far in advance should an anniversary reminder fire?
- Unlike birthdays, a ping on the day is usually not enough, because an anniversary tends to need planning — booking a table, buying something, taking time off. Two reminders work well: one about two weeks ahead for planning and one on the day. Apple and Google Calendar both allow two alerts per event; Birday allows any number.
- Can I track death anniversaries and other remembrance dates the same way?
- Yes, and it's one of the reasons a dedicated setup earns its place. Birday carries death anniversaries as their own event type, and Endearist treats every important date on a contact equally. With calendar-event solutions it's worth setting the alert differently than for happy occasions — a few days before, say, so the day itself doesn't open with a notification.
