Quick verdict
The Tempdrop app is not just a companion screen for the sensor. It is the charting layer that turns overnight temperature data into a usable cycle record.
The most important pricing fact is that the app has a genuinely useful free tier. You can sync the sensor, see temperature results, chart fertility signs, set manual interpretation markers, review cycle history, export charts, and use calendar features without maintaining Premium.
Premium adds automation and guidance rather than simply unlocking the sensor. Current paid features include sleep data, fertility insights, automatic interpretation of temperature and cervical mucus, fertile-window information, ovulation estimates and verification, advanced calendar information, and the Tempdrop Academy course.
- Included trialEvery Tempdrop purchase currently includes a 2-month Premium trial
- Premium priceCurrent official materials list US Premium around $6 per month or $48 per year, while Tempdrop's latest FAQ tells users to check the app for their exact local price
For an experienced fertility-awareness user, the free app may be enough. For a beginner, Premium is more useful because it reduces manual interpretation and adds education.
What Is the Tempdrop App?
The Tempdrop app is available for iOS and Android.
It has four main jobs:
- Connect to the Tempdrop sensor
- Sync overnight data
- Build and display cycle charts
- Record fertility signs and symptoms
Premium adds a fifth job:
- Interpret more of the data automatically
The sensor and app are designed as one system. The sensor collects overnight data, while the app turns that data into a fertility chart.
Do You Need the App to Use Tempdrop?
Yes, the app is the normal way to retrieve and view Tempdrop results.
The sensor does not have a display that shows your nightly temperature directly.
You wear it overnight, then use Bluetooth to sync with your phone.
That design keeps the sensor small and focused.
Is the Tempdrop App Free?
Yes.
Tempdrop offers a free version that remains usable after your Premium trial ends.
This is not a demo that becomes useless without payment.
Current free features include
- Sensor sync
- Temperature-results history
- Chart view
- Multiple symptom tracking
- Manual cover-line tools
- Manual temperature-shift count
- Manual Peak-day tools
- Data backup
- Cycle history
- Cycle status
- Chart export
- Chart sharing
- Calendar view
That is enough for many manual fertility-awareness workflows.
Tempdrop Premium Features
Premium is designed for people who want the app to do more interpretation.
Current Premium features include:
- Sleep data
- Fertility insights
- Automatic temperature interpretation
- Cervical mucus interpretation
- Predicted fertile window
- Real-time fertile-window support
- Ovulation estimate
- Ovulation verification
- Advanced calendar information
- Tempdrop Academy
The difference is not "data vs no data".
It is more like "manual charting vs assisted charting".
Home Screen
The Tempdrop home screen uses a cycle wheel to show current cycle information.
Current navigation guidance says users can move around the wheel to inspect different days.
Premium users receive more fertility-status information in this view.
The home screen also provides access to sensor syncing and recent temperature results.
Results List
The results list lets you review recent temperature readings.
Current Tempdrop help documentation describes a 30-day history in the main result display, with Premium users also seeing cycle-phase information.
This is useful when you want to check the raw nightly sequence without opening the full chart.
Chart View
The chart is where Tempdrop becomes a fertility-awareness tool rather than a simple thermometer.
You can view:
- Temperature pattern
- Cycle days
- Symptoms
- Manual markers
- Fertility signs
- Interpretation information
BBT is most useful as a pattern across multiple days rather than as one isolated number.
The chart makes that pattern visible.
Manual Cover Line
Free users can manually set a cover line.
A cover line helps visually separate lower pre-ovulatory temperatures from the higher post-ovulatory temperature pattern under methods that use this approach.
The exact rules depend on the fertility-awareness method you follow.
Do not invent your own contraceptive rules from a chart.
Temperature Shift Count
The free app includes manual temperature-shift counting.
This helps experienced users apply their chosen method's rules to the chart.
Premium can automate more interpretation, but understanding the underlying rule remains valuable.
Peak Day Tools
The app lets you mark or work with a Peak day for cervical mucus.
This matters because symptothermal fertility-awareness methods commonly combine temperature with cervical mucus rather than relying on temperature alone.
Symptom Tracking
You can log additional cycle information inside the app.
Examples can include:
- Cervical mucus
- Bleeding
- LH testing
- PMS symptoms
- Notes
- Other observations supported by the current app
Combining signs can make the chart more useful than a temperature-only list.
Calendar View
The calendar provides a cycle overview.
Free users with regular cycles can access period-prediction functionality.
Premium provides more fertility and ovulation information.
Predictions are not guarantees. Tempdrop's own help guidance warns that ovulation can move in any cycle.
Premium Fertile Window
Premium can show a predicted fertile window.
Tempdrop visually distinguishes predicted information from later verified information.
Before ovulation, the app can show a predicted range based on available cycle data.
After sufficient temperature information, the display changes to indicate verification.
This is a useful interface choice because prediction and confirmation are not the same event.
Real-Time Fertility Tracking
If you record cervical mucus, the app can update the fertile window based on your current observations.
That means live body signs can override or extend a calendar prediction.
This is particularly important because a predicted ovulation date can be wrong in any given cycle.
Cervical Mucus Cross-Check
Tempdrop offers a setting that can require both:
- A valid cervical-mucus Peak day
- A qualifying temperature shift
before ovulation is verified.
This is one of the more advanced features in the app because it connects two fertility signs.
It can be useful for users following methods that rely on a double-check approach.
Tempdrop App and Irregular Cycles
The app can still chart irregular cycles.
However, Tempdrop's current guidance says predictions are not available in the same way for irregular cycles.
That is a sensible limitation.
Calendar prediction becomes less reliable when cycle timing varies significantly.
Measured signs remain more important.
Sleep Data
Premium users can view sleep information derived from the overnight session.
Current metrics include:
- Time taken to fall asleep
- Number of interruptions
- Length of interruptions
- Total sleep time
- Deep-sleep duration
- Overall sleep score
Tempdrop is still a fertility-first device, not a full sleep wearable.
Think of the sleep data as a useful bonus rather than the main reason to buy it.
Fertility Insights
Premium adds personalised fertility-related information based on logged data.
This can include:
- Cycle-phase context
- Predicted fertile days
- Ovulation information
- Temperature interpretation
- Educational notifications
The app is designed to make charting more approachable.
Tempdrop Academy
Academy is an interactive fertility-awareness learning feature.
It is available through the app's Learning Center for Premium users.
This is especially valuable for beginners because a fertility chart without education can be confusing.
Academy is not a replacement for personalised medical care or formal instruction if you are using fertility awareness for contraception.
Chart Export
Free users can export and share charts.
This is useful if you want to:
- Review with a fertility-awareness educator
- Discuss with a clinician
- Keep external records
- Compare cycles
- Save a chart outside the app
Exportability is an important data feature because your history should be usable beyond one screen.
Data Backup
Tempdrop includes account-based data backup.
That reduces the risk of losing cycle history when changing phones.
Use a secure account password and keep access to your registered email.
Syncing Tempdrop
The typical sync flow is:
Open the app
Choose the sensor-sync option
Long-press the Tempdrop button as directed
Let Bluetooth connect
Wait while the night is transferred
Review the result
Tempdrop 2.0 syncs one night's data relatively quickly.
Does the Phone Need to Stay Beside You All Night?
No.
The sensor records independently while you sleep.
Your phone is used when you sync.
This is useful for users who keep phones away from the bed.
How Much Data Does Tempdrop Store?
Current quick-start guidance says Tempdrop 2.0 can hold around 60 hours of recording data between syncs.
The original model stored much less.
Daily syncing remains best practice.
If you repeatedly record without syncing and fill the sensor memory, data can be lost.
Tempdrop Premium Price
Tempdrop's latest FAQ directs users to in-app pricing.
Current official material lists US pricing at about:
- $6Per month, approximate US rate
- $48Per year, approximate US rate
Local pricing can vary.
The annual plan is cheaper per month if you use Premium continuously.

The app needs the sensor
This guide lists Tempdrop 2.0 at $149, reduced from $189, including the free app and a 2-month Premium trial.
Check current Tempdrop offerAffiliate link. Pricing, discounts, shipping, taxes, eligibility, renewal terms and availability can change, and the final checkout controls what you actually pay.
Privacy and Sensitive Data
Fertility data is sensitive.
Tempdrop's app stores information about cycles and health observations.
Good practice includes
- Use a strong password
- Protect your phone
- Keep app-store accounts secure
- Review privacy settings
- Avoid sharing exported charts publicly unless intended
- Understand what information you enter manually
The app may be convenient, but fertility data still deserves careful handling.
Can You Use Tempdrop With Other Apps?
Tempdrop supports exports and has offered health-data integrations in parts of its ecosystem.
Compatibility can change with operating-system updates.
If your entire workflow depends on exporting into a specific third-party fertility app, verify that integration before buying.
Tempdrop App for Trying to Conceive
The app can help visualise temperature shifts and combine them with other fertility signs.
That can support timing awareness.
It does not diagnose infertility or guarantee conception.
If you have concerns about cycle health or conception, use the data as part of a broader discussion with a qualified clinician.
Tempdrop App for Avoiding Pregnancy
Important
Do not treat a predicted fertile window as a standalone contraceptive instruction.
If you use fertility awareness to avoid pregnancy:
- Learn a validated method
- Follow its rules
- Use real-time observations
- Understand how illness, sleep, medication, alcohol, and other factors can affect temperature
- Seek instruction if needed
Tempdrop itself warns users not to rely only on predictions for fertility decisions.
Tempdrop App for Postpartum Charting
The app can record data during the return of fertility postpartum.
This is a specialised situation.
Postpartum cycles can be irregular, and ovulation can occur before the first period.
Use a postpartum-specific fertility-awareness protocol if avoiding pregnancy.

Can I track cervical mucus?
Yes.
Does Tempdrop predict fertile days?
Premium can show predictions, but real-time fertility signs can change the fertile window.
Does the app work with irregular cycles?
Yes for charting. Predictive functionality is more limited when cycles are irregular.
Can I export my Tempdrop chart?
Yes.
Does the app track sleep?
Premium includes sleep information.
Do I need my phone while sleeping?
No. The sensor records overnight and syncs later.
Final Verdict on the Tempdrop App
Final verdict
The Tempdrop app gets one important thing right: it does not force every sensor owner into a permanent subscription.
The free tier is strong enough for manual charting, especially if you already understand fertility-awareness rules.
Premium is valuable when you want interpretation rather than just data.
Its strongest additions are automatic temperature and mucus interpretation, fertile-window information, ovulation verification, sleep data, and Academy.
Use the 2-month included trial to decide which type of user you are.
If Premium makes your chart meaningfully easier to understand, the annual option can be reasonable.
If you mainly want reliable overnight temperatures, the free app keeps Tempdrop useful without turning the device into a recurring bill.
