Today
The activity ring shows your step progress for the day, followed by today's plan, the meal log and quick actions.
Tap "Log Today" to record a meal on one screen, or "Log Steps" to backfill walks Apple Health did not capture.
iOS · iPhone & iPad
Log your workouts, meals
and health — the data
stays yours.
EnjoyFitness puts workout logging, meal check-ins, health metrics and weekly reports into one dark interface. It reads steps, heart rate, body mass and sleep from Apple Health — read-only — and there is no account, no ads and no server. Your entries are written to your own device by default.
- No sign-up
- Local-first storage
- Read-only Apple Health sync
- Dark mode
- iPad support
Five tabs
From today's ring to a full week of trends
Five tabs cover the full loop: log, review, analyze. Every chart is built from data you actually entered or synced read-only from Apple Health. There is no pre-seeded demo data anywhere in the app.
Workout
Running, cycling and strength sessions — record duration, calories and notes, written to local storage the moment you save.
This week's calorie bars sit beside your recent sessions, so you can see at a glance how often and how long you trained.
Data
A workout-duration trend chart backed by three stat cards — total time, average, session count — with a week / month toggle.
The weekly report card rolls up workouts, steps, body metrics and goal completion, and turns them into shareable text in one tap.
Health
Line charts and recent entries for body mass, heart rate, blood pressure and sleep. Sleep only ever shows values you actually recorded.
The "+" in the top-right adds a reading any time; steps and similar metrics sync in read-only from Apple Health.
Me
Goals and completion, the local-storage switch, the iCloud sync switch, and reminder settings.
Workout, water and sleep reminder times are all editable — water supports 1 / 2 / 3 / 4 / 6 hour intervals.
Privacy first
No account system, no email, no phone number. No third-party analytics SDK, no ad SDK.
Data is written to fitness_data.json inside the app sandbox. Turn off "Local Storage" and new entries stay in memory only.
- No account
- We collect no email, no phone number, no identifier of any kind. Open it and it works.
- No server
- The app uploads nothing to any server of ours — there is no server-side database.
- No tracking
- No third-party analytics, attribution or advertising SDKs, so there is no cross-app tracking.
- Your control
- Clear everything at any time, or revoke Health access in Settings → Privacy.
Interface
Bright green on a dark canvas
Both iPhone and iPad get native layouts. On iPad, charts and lists open up to use the larger screen, and dark mode stays easy on the eyes during long sessions.

Terms of Use
>This agreement is between you (the "User") and EnjoyFitness ("we", "us") regarding your use of the EnjoyFitness mobile application (the "App"). By downloading, installing or otherwise using the App, you confirm that you have read and agree to be bound by every term of this agreement. If you do not agree to any term, stop using the App and uninstall it.
1. What the App Does
The App is a local workout, meal and health tracker for iOS / iPadOS. It provides:
- Workout logging: record duration, calories and notes for running, cycling, strength training and more;
- Meal logging: record each meal's name and calories;
- Health metrics: record body mass, heart rate, blood pressure and sleep, and sync step count, heart rate, body mass and sleep analysis from Apple Health — read-only;
- Goals and plans: set target values and daily plans, and track completion;
- Stats and weekly reports: view trend charts by week or month and generate shareable weekly report text;
- Local reminders: fire workout, water and sleep reminders on your device at the times or intervals you set.
We may adjust, improve, add or remove features at any time, and doing so does not put us in breach of this agreement.
2. Accounts and Data
The App has no account system. There is no sign-up or log-in, and we never ask for your email, phone number or any other identifier.
Everything you enter is stored by default inside the app sandbox on your own device (in a file named fitness_data.json),
and is never uploaded to our servers.
If you turn on iCloud sync in the Me tab, your data is synced through Apple's iCloud key-value store to your own Apple Account. That sync is provided by Apple and governed by Apple's terms and privacy policy, and we cannot access its contents.
You can switch off "Local Storage" in the Me tab — after that, new entries live in memory only and disappear on the next launch — or use "Clear All Data" to delete every local record. Deleted data cannot be recovered — please proceed with care.
3. Acceptable Use
When using the App, you must not:
- reverse engineer, decompile or disassemble the App, or attempt to obtain its source code;
- copy, modify or redistribute the App, or use it for any commercial purpose;
- remove, obscure or alter any copyright, trademark or other proprietary notice in the App;
- use the App for any activity that violates applicable law.
4. Health Disclaimer
The App is not a medical device and does not provide medical care.
All data, charts, statistics and weekly reports in the App are for personal record-keeping and reference only. They are not medical advice, a diagnosis or a treatment plan, and they do not replace the opinion of a qualified physician.
All data, charts, statistics and weekly reports in the App are for personal record-keeping and reference only. They are not medical advice, a diagnosis or a treatment plan, and they do not replace the opinion of a qualified physician.
You are responsible for judging whether your physical condition suits a given workout or meal plan. Before starting any new exercise, diet or weight-loss programme, please consult a physician or another qualified healthcare professional. If you feel unwell while using the App, stop the activity immediately and seek medical help.
Data synced from Apple Health comes from Apple and the underlying sources. We make no warranty as to its accuracy, completeness or timeliness.
5. Intellectual Property
All intellectual property in the App — including but not limited to its code, interface design, icons, chart styling, copy, trademarks and related assets — is owned by us and protected by applicable law and international treaties. This agreement grants you only a limited, non-transferable, non-sublicensable licence to use the App for personal, non-commercial purposes. No ownership is transferred to you.
Apple, iPhone, iPad and Apple Health are trademarks of Apple Inc. All rights belong to their respective owners.
6. Disclaimers and Limitation of Liability
The App is provided "as is". To the maximum extent permitted by law, we disclaim all warranties, express or implied, including the implied warranties of merchantability, fitness for a particular purpose and non-infringement.
To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, punitive or consequential damages arising from your use of or inability to use the App, including lost data, lost profits, physical discomfort or harm to health. If we are nonetheless found liable, our aggregate liability is capped at the amount you paid for the App (zero, if the App was free).
7. Changes, Interruptions and Termination
We may modify, suspend or discontinue the App at any time for business, technical, legal or regulatory reasons (or any feature within it), and we will try — but are not obligated — to give notice in advance. We may also terminate your licence if you breach this agreement.
After termination, the provisions on intellectual property, disclaimers, limitation of liability and dispute resolution survive in accordance with their nature.
8. Changes to This Agreement
We may revise this agreement from time to time. The revised version is posted on this page with an updated effective date. If a revision materially affects you, we will notify you in an appropriate way inside the App. Continuing to use the App after a revision takes effect means you accept the revised agreement.
9. Governing Law and Dispute Resolution
This agreement is governed by and construed in accordance with the laws of mainland China, excluding its conflict-of-law rules. Any dispute arising out of or relating to this agreement should first be resolved through friendly negotiation; failing that, either party may bring an action before the competent people's court.

Privacy Policy
The short version: we collect no personal information, because the App has no server, no accounts and no need for you to tell us who you are.
This Privacy Policy explains how EnjoyFitness ("we", "us") handles information when you use the App. It applies to the EnjoyFitness app on iOS / iPadOS.
1. What We Collect
1.1 Data you enter
When you use the logging features, we save what you type. Specifically:
| Data type | Fields | Purpose |
|---|---|---|
| Workout log | Type, duration, calories burned, date, notes | Build workout stats and trend charts |
| Meal log | Meal name, calories, date | Compute daily intake |
| Health metrics | Body mass, heart rate, blood pressure, sleep duration, timestamp | Draw metric line charts |
| Steps | Date and step count | Drive today's activity ring and the weekly report |
| Goals and plans | Goal name, target value, current value, plan items | Show completion |
| Nickname (optional) | Text you enter in the Me tab | Display purposes only |
The nickname is entirely optional. Leave it blank and the UI falls back to a generic avatar and "You / No nickname set", and nothing else changes.
1.2 Data from Apple Health (read-only)
With your explicit permission, the App asks the system HealthKit to read the following:
- Step count
- Heart rate
- Body mass
- Sleep analysis
The App only reads. It never writes to Apple Health.
Technically, the App requests an empty share (write) authorisation set from HealthKit, so you will never see data created by this App inside the system Health app.
Technically, the App requests an empty share (write) authorisation set from HealthKit, so you will never see data created by this App inside the system Health app.
Permission is requested by a system prompt the first time you use a relevant feature — never automatically at launch. You can revoke it any time in iOS Settings → Privacy & Security → Health. After revocation, the App keeps only what was already synced or entered manually.
1.3 What we do not collect
We do not collect any of the following:
- Name, national ID number, phone number, email or any other identifier;
- Contacts, photos, calendars, microphone or camera content;
- Precise or coarse location;
- Advertising identifiers (IDFA) or device fingerprints;
- Usage telemetry or crash analytics — the App ships no third-party analytics or advertising SDK.
2. How We Use Information
Everything described above is used only to render the interface and compute statistics on your device: drawing the activity ring and trend charts, computing totals and averages, generating weekly report text, and firing local reminders at the times you set.
We never use this data for advertising, profiling, automated decision-making or any purpose not described in this policy.
3. Where Data Is Stored
By default, data is written as a JSON file into the Documents directory of your device's app sandbox
(fitness_data.json), protected by the iOS sandbox and device encryption.
The file is included in system backups (iTunes or a full iCloud backup), which Apple manages and encrypts.
If you turn on iCloud sync, a copy is written through Apple's
NSUbiquitousKeyValueStore (iCloud key-value storage)
to your own Apple Account so your devices stay in sync.
That channel is operated and encrypted by Apple — we cannot read its contents.
Apart from the above, your data never leaves your device and we have no server-side database to put it in.
4. Sharing, Transfer and Disclosure
We do not sell, rent, share or transfer your data to any third party. The App contains no third-party SDK and sends nothing to any server of ours or anyone else's.
The weekly report's "Share" action opens the iOS system share sheet (
UIActivityViewController). The text is generated only when you tap Share,
and you choose where it goes. We cannot see who you shared it with and we keep no copy.
Before sharing, note that the report may include sensitive values such as body mass or heart rate.
>We may disclose information only in these rare cases:<
- Where required by applicable law or a binding request from a court or government authority;
- Where necessary to protect the life, property or other significant lawful interests of us, you or the public.
5. Security
We rely on the sandboxing, Data Protection and device encryption that iOS provides, and we follow data minimisation: data we never collect needs no protection.
Please understand that no technical measure can guarantee absolute security. Keep your passcode safe and device encryption enabled. We cannot accept responsibility for leaks caused by a lost or jailbroken device, or by you handing your device to someone else.
6. Your Rights and Controls
Control over your data stays in your hands:
- Access and export: every entry can be viewed, edited and deleted directly in the App;
- Stop local persistence: switch off "Local Storage" in the Me tab — new entries then live in memory only and clear on the next launch;
- Clear all data: use "Clear All Data" in the Me tab to delete every record on this device at once;
- Revoke Health access: turn it off any time in iOS Settings → Privacy & Security → Health → EnjoyFitness;
- Turn off reminders: flip the switch in the Me tab, or disable notifications for the App in system Settings;
- Uninstall the App: uninstalling deletes everything in the app sandbox.
All of the above take effect on your device immediately. You never need to file a request with us, and we have no ability to perform or undo them for you.
7. Notifications
Workout, water and sleep reminders use iOS local notifications (
UNUserNotificationCenter),
scheduled and delivered entirely on your device. Nothing passes through a server and there is no remote push.
We never learn whether you actually saw a reminder.
8. Children's Privacy
The App is not designed for children under 14 and we do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us personal information, contact us using the details below and we will help delete it promptly.
9. Third-Party Services
The App integrates no third-party analytics, advertising, attribution or social SDK. Apart from the system share sheet you invoke yourself and the optional iCloud sync (both provided by Apple), the App connects to no third-party service.
How Apple handles App distribution, iCloud sync and system frameworks is governed by the Apple Privacy Policy ; we suggest reading it too.
10. Updates to This Policy
We may revise this Privacy Policy from time to time. Revisions are posted here with an updated "Last updated" date. If a revision involves a material change in how we handle data, we will give prominent notice inside the App and, where required, obtain your consent again.
11. Contact Us
If you have questions, comments or requests about this Privacy Policy or how the App handles data, reach us using the contact details in the footer. We will respond within a reasonable time.
