Estimated or measured, which hormone tracker do you need?
Hello Phase, Moody Month, Stardust, Clue and Flo use no strips and estimate where you are in your cycle from the period dates you log. Inito, Mira, Proov and OOVA read a urine test strip and report LH, which surges before ovulation, plus E3G and PdG, the forms of estrogen and progesterone found in urine.
Estimated from cycle dates
A typical curve fitted to the period dates you log
- Hello Phase
- Moody Month
- Clue
- Flo
Urine test strips
Measured LH, E3G and PdG, and some add FSH
- Inito
- Mira
- Proov
- OOVA
Cycle dates plus wearable temperature
Still an estimate, with one real body signal
- Stardust
Bearable has no hormone data, so it sits in none of the three groups.
The difference matters most around ovulation. A study comparing urine with blood found that "The rise in estrogen and LH always occurred before ovulation" and "the progesterone rise from baseline always occurred after ovulation", so a strip app can watch LH climb and then use PdG to confirm that ovulation happened.
A calendar app assumes ovulation lands at a set point, and Hello Phase, for example, places it about 14 days before your next expected period. Real cycles vary more than that, and the NICHD says ovulation "can occur anywhere between 10 and 21 days" after a period starts. A 2026 study using Mira also found cycles without ovulation in 11% of regularly cycling participants, which no calendar can notice.
Who should pay for test strips?
Strips are worth it if you are trying to conceive and want to see your LH surge and confirm ovulation with PdG, or if your cycles vary so much that calendar predictions keep missing. They make less sense if you mostly want to understand your month, since Inito strips alone run about $39 to $49 a cycle.

Find the right app for you
Can an app tell your hormone levels without a test?
No, an app cannot tell your actual hormone levels without a test. It can only draw the pattern that is typical for a cycle of your length, which is enough for planning your week or seeing how your mood lines up with your cycle, and as MedlinePlus puts it, "It is hard to know exactly when ovulation will happen."
No hormone test settles everything either. IAPMD says "PMDD or PME cannot be diagnosed through blood, hormone, or saliva tests", so if mood changes before your period worry you most, our guide to PMDD tracker apps is the better place to start.
Are hormone tracker apps private?
Some are far more private than others, and price does not predict which. Apple's privacy labels are filled in by each developer rather than independently audited, and on those labels OOVA and Proov link no data to you and declare no tracking, while Inito links only your contact info. Mira, Moody Month, Stardust, Clue, Flo and Bearable all declare "Data Used to Track You", and in 2021 the FTC finalized an order with Flo over allegations that it shared sensitive health data with Facebook and Google.
Hello Phase has no Apple label because it is not in the App Store. It needs no account, keeps your logs on your phone, shows no ads, and its Google Play Data safety section says no data is shared with third parties. Our FAQ lists what the optional AI coach sends once you agree.
Apps we left out and why
Hormona: Period Tracker. Hormona+ costs $69.99 a year and its site sells at-home urine hormone kits, but on 26 October 2026 we could not find the kit price or US availability, so we could not compare its real cost.
TALIA: Menopause & MHT Tracker. Its Apple label says "Data Not Collected", but it had no US ratings on 26 October 2026, so it is too new to rank.
Cycle syncing apps. 28, Lively and Harmony center on workouts and food by phase, and we compare them in our best cycle syncing apps guide.
How to choose
- If you want a hormone chart without strips, start with Hello Phase on Android, or Moody Month or Stardust on iPhone.
- If you are trying to conceive or want proof that you ovulated, choose a strip app, where Inito suits most people and Proov costs least to start.
- If privacy comes first, Hello Phase keeps your data on your phone with no account, and OOVA and Proov have the cleanest Apple labels.
- If symptoms matter more than hormones, Bearable shows what tends to go with them.
Questions people ask
What is the best hormone tracker app?
Hello Phase is the best hormone tracker app if you want a free hormone chart with no test strips, on Android, drawn from your cycle dates with no account. Inito is the pick for measured hormone numbers, reading E3G, LH, PdG and FSH from urine with a 4.94 rating from 5,302 US App Store ratings.
Is there a hormone tracking app without test strips?
Yes, Hello Phase, Moody Month, Stardust, Clue and Flo all work without test strips by estimating your hormones from your cycle. The estimated hormone chart in Hello Phase is free on Android, and Moody Month's daily hormone forecast costs $36.99 a year on iPhone and Android.
Can a hormone tracker app confirm ovulation?
Only apps that read test strips can confirm ovulation, because they detect the PdG rise that follows it. A study comparing urine with blood found the progesterone rise always occurred after ovulation, while calendar apps can only estimate when ovulation probably happened.
How much does a hormone tracker cost?
Apps that estimate hormones are free to start, and their paid tiers are listed at $29.99 to $39.99 a year, while strip trackers cost $59.99 to $249 to start plus refills, such as $49 for 15 Inito strips.
Does Hello Phase measure hormones?
No, Hello Phase estimates your hormones and does not measure them. It draws typical estrogen and progesterone curves for a cycle of your length, with ovulation placed about 14 days before your next expected period, and it is on Android only.
Try the free hormone chart
If you are on Android and want to see an estimated hormone chart for your own cycle before buying strips, Hello Phase is free and needs no account. The pricing page lists what Plus adds.
