The Best Private Sex Tracker Apps of 2026
Looking for the best private sex tracker apps? One of the six below is our own app, Intimassy, so read this page knowing who wrote it.
On iPhone, Nice and xTracker have the strongest listings. Spicee is the playful couples one. Clue is a huge cycle tracker that covers the basics on the side.
- Intimassy (Android, iPhone and Apple Watch): encrypted, 13 fields per entry, health records and cycle tracking. Ours.
- Nice (iPhone, iPad): no account, data on the phone per its site.
- xTracker (iPhone, iPad, Mac, Watch): STI and period trackers built in.
- Spicee (Android and iPhone): games and challenges for couples.
- Sex Tracker & Calendar (Android): a calendar and statistics, kept on the phone.
- Clue (Android and iPhone): a cycle tracker with a Sex Life section.
Every figure here comes from the public store listings, checked in October 2026. Every row is built the same way, from what the listing says and nothing more.
Two notes for reading the table. A Google Play download bracket is a floor, so 100K+ means at least 100,000. The App Store listings show no download counts, which is why the iPhone-only rows lean on ratings counts instead. The table keeps to the store numbers; what each app covers sits in its own section below.
| App | Rough downloads | Store rating | Privacy in one line |
|---|---|---|---|
| Intimassy (ours) Android, iPhone, Apple Watch | 100K+ (Play) | 4.4 (2,380) Play, new on the App Store | Encrypted, PIN lock, account for sync and backup |
| Nice iPhone, iPad | Not published | 4.5 (about 4,900, US) | On the phone, no account |
| xTracker iPhone, iPad, Mac, Watch | Not published | 4.4 (about 2,400, US) | Label: data linked to identity |
| Spicee Android, iPhone | 10K+ (Play) | None on Play, 5.0 (1, US) | PIN lock, no data shared, as declared |
| Sex Tracker & Calendar Android | 100K+ (Play) | 4.4 (470) | On the phone, no account, no data collected |
| Clue Android, iPhone | 50M+ (Play) | 4.5 Play, 4.8 App Store | Label: data linked, some shared |
Intimassy: ours, on Android, iPhone and Apple Watch
Full disclosure once more: Intimassy is our app. Its row uses the same store facts as every other row, and this section sticks to the listing and the product page the same way.
Intimassy is a private record for one person. Each record is encrypted on the device, a PIN can lock the whole app, and nothing anyone writes in it is ever shown to another user. It does run on an account. The account keeps the history and every customization safe, and restores all of it on any phone through encrypted sync and backup.
One entry can hold 13 fields, from partner and position to duration, protection and satisfaction, with photos kept in a private gallery. An entry can be saved as a named template and filled in later with one tap, and fields you never use can be hidden.
From those entries the app builds more than 15 statistics. One of them sets this month against the last, or any two months or years side by side. Partner profiles keep each partner's history, and a past partner can be archived without losing it. The app can also show a personal rhythm next to anonymous global statistics.
Two kinds of record sit next to the log. Health records keep sexual health details, such as an STD, with when it started and whether it is ongoing, and can mark those dates on the calendar. Cycle tracking marks period days for you or a partner, and shows the estimated next period, fertile window and ovulation day. Those are estimates only, not medical advice and not a contraceptive method.
On Apple Watch, an activity can be timed on the wrist, or recorded from a template with one tap. Template names hide when the wrist is lowered.
On Google Play it has 4.4 stars from 2,380 ratings and more than 100,000 downloads. The iPhone version went live on the App Store in August 2026 and is too new for its ratings to mean much.
Nice: the iPhone pick that skips the account
Nice runs on iPhone, iPad and Apple Vision and asks for no account. Its maker says sensitive data lives only on the phone. Its App Store listing adds that entries can sync through iCloud with a partner, as a shared calendar.
The listing covers activities with custom details, partner records including STI and STD test dates, places on a map, photo and video attachments, trends from daily to yearly, and Apple Health integration.
Its App Store privacy label reads Data Not Linked to You, and lists only crash and performance data. On the US App Store it stands at 4.5 stars from about 4,900 ratings.
xTracker: STI and period trackers on Apple devices
xTracker runs on iPhone, iPad, Mac, Apple Watch and Apple Vision.
It covers calendar and event views, a shared calendar, statistics with partner-based insights, an STI and STD tracker, a period tracker, a map of events and passcode protection.
The privacy label on its listing names health and fitness data, contact info, user content and usage data as linked to identity, and purchases as used for tracking. That is the listing's own wording, not our judgment. It stands at 4.4 stars from about 2,400 US ratings.
Spicee: a couples game more than a record
Spicee is on both Android and iPhone. The listing reads like a game night: an activity heatmap, a private world map of places, love coupons a partner can redeem, couples challenges, conversation games and a PIN lock. Its iPhone listing has you sign in once to share one space across two phones.
It is early. Google Play shows 10K+ downloads and no star rating yet, and the iPhone listing is too new for its ratings to mean anything. Its Play data safety section declares encryption in transit, no sharing with third parties, and possible collection of location.
Sex Tracker & Calendar: the plain one
Wolftooth's Sex Tracker & Calendar keeps to a calendar and statistics, shown as graphs and tables. Each time can hold fields such as partner, position, place, protection, duration and a score, plus photos. The listing says it needs no membership and keeps all data on the phone, with an optional password, optional encryption and a discreet mode that renames the app icon.
It runs on Android, at 4.4 stars from 470 ratings and past 100,000 downloads. Its data safety declaration is the shortest of the six: no data collected, none shared.
Clue: the mainstream neighbor
Clue is a menstrual cycle tracker first, and by far the biggest name here: 50M+ downloads and about 1.5 million ratings at 4.5 stars on Google Play, plus 4.8 stars from about 405,000 ratings on the US App Store.
Its Sex Life section offers 12 tracking options, from protected and unprotected sex to low sex drive, per Clue's own article on the feature.
Its App Store privacy label lists identifiers as used for tracking, and health data, location, contact info and sensitive info as linked to identity, with purposes that include advertising. Play's data safety section says some data may be shared with third parties. The same Clue article states the company never has and never will sell personal health data. Both things sit on the record, side by side.
How do you judge a private sex tracker app?
Five questions did most of the sorting here, and they carry over to any app not in the table.
- Does it ask for an account, and what for? A record tied to a login has a name on it, so the login should buy something concrete. Nice and Sex Tracker & Calendar state plainly that no account is needed. Intimassy uses one for a stated job: keeping the history and customizations safe and restorable on any phone. Spicee's iPhone listing has you sign in to share a space with a partner. The other listings do not say either way.
- Where does the record live? Nice and Sex Tracker & Calendar say on the phone, and Nice can sync with a partner through iCloud. Intimassy encrypts each record on the device and keeps everything restorable on any phone through encrypted sync and backup. When a listing is quiet on this, that silence is itself worth noticing.
- What does the privacy label declare? Every listing in the table carries one. Google Play notes on each listing that the developer provided this information, so read a label as the maker's statement, not a test result.
- Can the app lock itself? Phones get handed across a dinner table. Intimassy and Spicee list a PIN lock, Nice lists a passcode and biometrics, xTracker a passcode. Sex Tracker & Calendar offers an optional password.
- Does it keep health and cycle records next to the log? Intimassy has both health records and cycle tracking. xTracker lists an STI and STD tracker and a period tracker. Nice records STD and STI test dates. Clue is a cycle tracker first, with sex tracking on the side.
What this comparison cannot tell you
It reads listings. Nobody tested six apps in a lab for this page, and a feature list is the maker's own wording, ours included.
The numbers drift. Ratings move and download brackets step up. Treat every figure as the reading from one day in October 2026. The App Store figures are from the US store.
How an app feels day to day is also beyond a table. A calendar someone opens gladly beats a fuller one they avoid, and no listing measures that.
How to choose
Ours is the one built for exactly this, on Android, iPhone and Apple Watch, with health records and cycle tracking next to the log. If you want no account at all, Nice is the closest match on iPhone, and Sex Tracker & Calendar on Android. xTracker covers Mac and Apple Vision as well. If a shared game sounds better than a record, Spicee is aimed at you. If the cycle is the main thing you follow, Clue is the specialist.
Whichever you pick, the point of keeping a record is seeing a pattern. For a sense of what those patterns look like across many couples, start with how often couples have sex or where it usually happens.
