Updated 25 September 2026: a native app exists for iOS only; on Android the installable web app is the way. Previously on 21 September 2026: since tracker v6.2.6 the automatic photo check is off by default. On 18 August 2026: corrected the platform availability details.
Finding the right chastity app comes down to three things: does it actually track what you need, does it give the keyholder real control, and what happens to your data? This comparison covers the most-used options available in 2026 so you can make an informed choice.
What People Look For in a Chastity App
Couples and individuals exploring chastity as part of a D/s dynamic typically need a few core things from an app: a reliable wear time log, a way for the keyholder to monitor and set expectations, some form of verification that the device is still in place, and notifications to keep both parties aligned. Beyond features, privacy is a real concern — this is intimate data, and most people do not want it sitting on a third-party server they cannot inspect or control.
Comparison Table
| App | Platform | Hosting | Keyholder features | Cost |
|---|---|---|---|---|
| Chastity Tracker | Web + app on iPhone/Android native iOS app on request‡ | Docker (own server) or Portal† | Full keyholder dashboard, control requests, tasks with deadlines, training goals, AI seal verification (optional), penalty log | Free |
| Chaster | Web + app on iPhone/Android | Cloud | Lock management, events, shared locks | Free tier exists |
| Chastify | Web + app on Android (no iOS app) | Cloud | AI keyholder (no human partner required) | Paid |
| Kneel | Web + native app (App Store, Google Play) | Cloud | Keyholder management, tasks | Freemium |
| ChastiSafe | Web | Cloud | Basic keyholder controls | Free |
† The Portal is a goodwill service — instances run on trublue's server, not your own. See the explanation below.
‡ Installs straight from the browser, no app store involved — and what you install is your own instance address, not this website. On top of that, the native iOS app is available as a TestFlight beta on request; there is no native Android app, and on Android Chrome installs the web app like a regular app. How to get the app onto your phone.

What Makes a Good Keyholder App
Control Requests
The submissive partner should be able to request changes — unlocking, cleaning breaks, adjustments — and the keyholder should have a clear queue to approve or deny them. An app that relies on messaging apps for this loses the paper trail.
Wear Time Logging
Timestamps matter. A good chastity tracker records every lock and unlock event with exact times so both partners can review genuine wear history. Manual notes are easy to forget or manipulate; a timestamped log is not.
Verification
AI seal photo verification is one of the more useful features to appear in recent chastity apps. The device wearer photographs a tamper-evident seal, and the app checks whether it has been broken. It is not foolproof, but it adds a meaningful layer of accountability.
Training Goals and Penalties
Beyond basic logging, structured training goals let the keyholder define expectations — minimum wear durations, tasks with held conditions, milestones — and a penalty log records deviations. This structure is what separates a chastity management app from a simple diary.
Notifications
Push notifications keep the keyholder informed when the wearer logs an event or submits a request, and remind the wearer of goals or check-in requirements without the need for constant messaging.
The distinction worth knowing is between an installed web app and a native app from a store: both deliver push — though on iPhone and iPad only once the web app actually sits on the home screen rather than in a browser tab.
Privacy: Two Fundamentally Different Approaches
True Self-Hosting — Full Data Control
For anyone who takes privacy seriously, the cleanest solution is running the Docker container on your own server. Storage then happens entirely on your own infrastructure — no vendor lock-in, no dependency on a third party, no risk from policy changes or shutdowns. The one possible exception is the photo check: it is off by default; switch it on and submitted photos go to the AI service you choose, or you run it locally.
This requires a Linux server, a domain, and basic Docker knowledge — roughly 15–30 minutes of one-time setup. For technically comfortable users, it is the only option on this list that provides genuine data sovereignty.
The Portal — Convenient, but Not True Self-Hosting
The Portal automatically provisions an isolated instance: your own subdomain, your own database, no shared database access with other users.
However: instances run on trublue's server — not your own infrastructure. This is a personal side project, run privately and free of charge:
- No guarantees of uptime, data security, or continued operation
- No liability — for data loss, outages, or anything else
- No support obligations — this is a hobby project
- Suitable for users who have no server infrastructure of their own and prefer a one-click setup over full data control
If you genuinely want no data on third-party servers, run Docker on your own machine.
Chastity Tracker — Feature Overview
Chastity Tracker is built for D/s couples who want complete keyholder management. It covers the full feature set: timestamped lock/unlock log, optional AI seal photo verification, keyholder control requests, training goals, penalty log, statistics dashboard, and push notifications.
Option A — Docker (recommended for maximum privacy): Pull the Docker image and run it on your own server. Source code and setup guide on GitHub.
Option B — Portal (easy start, no server required): Set up your own instance in minutes at portal.chastitytracker.ch. Free — but your data lives on trublue's server. No guarantees.
Which App Is Right for You
Privacy is your priority and you are comfortable with Linux/Docker → Chastity Tracker via Docker on your own server. The only option on this list with genuine data sovereignty.
No server, but you want convenience → Chastity Tracker Portal as a goodwill service, or Chaster as an established cloud option with broad features.
Mostly using it on a phone → Chastity Tracker and Chaster both run as an installable web app (see ‡), and neither needs a store download. If data ownership matters to you alongside that, Chastity Tracker is the pick: it is the only app in this comparison you can run on your own server.
A store app is a hard requirement → Kneel is the only option on this list with an App Store and Google Play listing.
An AI-driven keyholder without a human partner → Chastify is purpose-built for that.
For most couples with an active D/s arrangement, Chastity Tracker — whether via Docker or the Portal — covers what actually matters day to day.
