Best Egg Freezing Tracking App 2026: 6 Apps Compared

According to SART, the Society for Assisted Reproductive Technology, US clinics reported 39,269 egg freezing cycles in 2023, a 39.2% jump from the year before^[1]. Egg freezing is one of the fastest-growing categories in assisted reproductive technology, and yet there is still no clear category-leader app the way Flo dominates period tracking.

If you're freezing your eggs, you already know it's a lot. Stim medications at the same time every night. Monitoring appointments every 2 to 3 days. A trigger shot at a precise hour.

And in between, side effects that are hard to predict: bloating, mood swings, exhaustion, the emotional reality of doing something this medically intense.

A regular period tracker won't help. Your clinic portal handles the protocol but rarely captures how you actually feel. This guide compares 6 apps that try to fill that gap.

Educational content, not medical advice. Egg freezing is a medical procedure. Always follow your fertility clinic's protocols and your reproductive endocrinologist's guidance.

Step 1: What Egg Freezing Tracking Actually Requires

An egg freezing cycle is its own thing. Not a natural cycle, not exactly the same as IVF (no transfer, no embryo development). The tracking needs reflect that.

Stim Phase Medication Tracking

A typical stim phase runs 8 to 14 days with daily injectable medications, usually gonadotropins like Gonal-F or Menopur. Mid-cycle, an antagonist like Cetrotide or Ganirelix gets added to suppress early ovulation. Then a trigger shot at a precise time, often in the middle of the night, sets up the retrieval 36 hours later.

The best apps send reminders for each medication, let you log when you actually took it, and surface the trigger timing prominently so you don't miss it.

Monitoring Appointment Tracking

Most cycles include 4 to 6 monitoring appointments, with bloodwork checking estradiol, LH, and progesterone, plus ultrasounds counting follicles and measuring lining. Having that data in one place across appointments lets you see your own trends, not just the latest result.

Side Effect and Symptom Logging

Stim medications cause real physical changes. Bloating is common as the ovaries enlarge. Mood swings, headaches, breast tenderness, sleep disruption, and fatigue are all reported by many people during stim. After the trigger, the bloating often peaks. Tracking what you're feeling day to day gives you a record to share with your clinic and a personal log of what your body went through.

Ovarian hyperstimulation syndrome (OHSS) is a possible complication of stim cycles. Your clinic will give you specific guidance on what to watch for and when to call. Tracking symptoms alongside your protocol gives you the data to bring to that conversation.

Emotional Tracking

Egg freezing is emotionally heavy in a way the medical timeline doesn't capture. The decision to freeze, the cost ($10,000 to $20,000 per cycle out of pocket in the US^[2]), the daily injections, the uncertainty about future use, the hormonal effects on mood. Many people find that tracking mood alongside the cycle helps them recognize patterns and talk about it with a partner, friend, or therapist.

Recovery After Retrieval

The first few days after retrieval often involve continued bloating, cramping, and slow recovery. Some people feel normal within a few days. Others take longer. Logging recovery alongside the cycle gives future you (or future cycles) a baseline.

Step 2: The 6 Apps Compared

For Dedicated Egg Freezing Tracking: Berry Fertility

Best if you want: A purpose-built fertility treatment tracker with an egg freezing care path, medication barcode scanning, and clinical features built for stim cycles.

Key Features

• Personalized care paths for egg freezing (and IVF, IUI, FET)
• Medication barcode scanning. Point your camera at the medication packaging and the app identifies it, sets reminders, and pulls up the matching injection video
• Stim phase tracking with stimulation date display in the calendar (added in the December 2025 update)
• Mature follicles chart showing follicle count progression across monitoring appointments
• Hormone trend visualization for estradiol and other monitoring labs
• Injection tutorial videos for self-administering each medication
• Treatment-stage badges in the daily calendar (stim, trigger, retrieval, recovery)
• EMR clinic integration with partner clinics (Pinnacle Fertility partnership covers 40+ US clinics as of late 2025)
• Partner sharing with removable access
• Symptom logging and lab result tracking

Strengths

• 4.9 App Store rating with 27 reviews (as of May 2026)
• Built by a team of Google alumni. Founded in 2022 and actively maintained, with quarterly feature updates
• The medication barcode scanner is the standout feature for stim. Scan the box, get reminders and videos automatically
• Egg freezing is one of their named care paths, not just an afterthought tacked onto an IVF app
• HSA/FSA eligible
• Cross-platform (iOS and Android)
• One reviewer noted on the App Store that Berry was the only fertility app they tried that didn't have distracting ads or features they didn't need during their egg freezing cycle

Limitations

• Smaller user base than larger fertility apps. 27 ratings is solid for the niche but modest in absolute terms
• EMR integration only works at partner clinics. If your clinic isn't on their list, you keep the consumer features but lose the sync side
• No nutrition, fitness, or broader health tracking
• No wearable integration
• Premium subscription required for the full feature set after the 7-day trial
• Built around treatment, not lifestyle, so it doesn't track how stim affects sleep, energy, or daily mood patterns the way a broader health app would

Privacy Considerations

Egg freezing data is extremely sensitive: treatment details, financial information, hormone levels, and a record of a decision many people aren't ready to share publicly. Here's how each app handles it:

• Berry Fertility integrates with clinic EMR systems, meaning data flows through existing healthcare infrastructure with its associated protections. This is the safest option if your clinic is a Berry partner.
• Viva Fertility states its AI learns user preferences while maintaining privacy. The privacy practices are stated in the App Store listing but the app is new enough that long-term privacy review hasn't happened yet.
• Glow experienced a data breach in 2024. Mozilla's Privacy Not Included review has rated Glow's privacy practices unfavorably. Worth careful consideration before signing up.
• Flo settled with the FTC in 2021 for sharing user data with Facebook and Google, and a $56M class action was settled in 2025. Anonymous Mode was added in response, but the history is worth knowing.
• Ovia partners with employers via workplace wellness programs and shares aggregated data. The privacy policy is lengthy and not always clear about what's shared. Worth reading before signing up.
• Go Go Gaia keeps data private and does not sell to third parties or show ads.

Tips for Tracking During Your Cycle

1. Set up medication reminders before your cycle starts. Enter every medication with its time before day one so reminders are ready to go. The first few days of stim are a lot, and the last thing you want is to be setting up reminders while also doing your first injection.
2. Log injection sites if your app supports it. Rotating helps reduce bruising and discomfort. If your app doesn't track this, a quick note in the daily log works fine.
3. Write down lab results right away. Your clinic will call with estradiol numbers and follicle counts. Log them immediately. Over 4 to 6 monitoring appointments, having a running record is more useful than trying to remember.
4. Track how you actually feel, not just what you took. Bloating, mood, sleep, energy. These are real data points for your clinic and a personal record of what your body went through.
5. Don't compare your numbers to others. Forums are full of follicle count comparisons. Your numbers are your numbers. Focus on your own trend across appointments.
6. Keep tracking after retrieval. Recovery is its own phase. Bloating often peaks after the trigger and takes time to come down. Tracking how recovery actually goes gives you a baseline if you do future cycles.
7. Capture the emotional side, not just the medical one. Many people describe the days around retrieval and the first period afterward as emotionally heavy. A daily mood log gives you something to look back on and patterns to share with a partner or therapist.

Frequently Asked Questions

Is there an app specifically for egg freezing?

Sort of. Berry Fertility supports egg freezing as a core care path with medication barcode scanning, a stim phase calendar, and a mature follicles chart. Viva Fertility markets its Eggion AI assistant specifically for egg freezing decisions and tracking. Most other dedicated fertility trackers cover egg freezing alongside IVF and IUI. There is no single app universally considered the category leader for egg freezing alone.

What should I track during an egg freezing cycle?

Most people track medication timing for stim shots and the trigger, monitoring appointments and bloodwork results, follicle counts from ultrasounds, daily side effects like bloating or mood changes, and recovery after the retrieval. Tracking the symptom side alongside the medical protocol gives you a fuller picture to share with your fertility clinic.

Can I use a regular period tracker for egg freezing?

A regular period tracker isn't designed for a stim cycle. Egg freezing involves controlled ovarian stimulation with daily injectable medications, monitoring every few days, a trigger shot at a precise time, and a retrieval procedure. None of that follows a natural cycle. A dedicated fertility treatment tracker or an all-in-one health tracker with medication and symptom logging will be more useful during your cycle.

How many people freeze their eggs each year?

According to SART, 39,269 egg freezing cycles were reported in the US in 2023, a 39.2% increase from the prior year. Egg freezing is one of the fastest-growing categories in assisted reproductive technology, which is part of why there's no single dominant app for it yet.

Will an app replace my clinic's portal?

A tracking app doesn't replace your clinic's portal. Your fertility clinic's portal handles the medical protocol, prescriptions, lab results, and care team communication. A tracking app sits alongside that, focused on the day-to-day experience: medication reminders, side effect logging, mood tracking, and a personal record of your cycle that the portal doesn't capture.

Are egg freezing tracking apps free?

Most have a free tier and several charge for premium. Berry Fertility offers a free tier with premium at $8.33 to $12.99 per month (HSA/FSA eligible). Viva Fertility is currently free. Flo, Glow, and Ovia have free tiers with premium subscriptions. Go Go Gaia is free for core features with optional premium at around $12 per month.

Should I track my emotional side or just the medical one?

Both, if you can. The medical side gives you data for your clinic. The emotional side gives you a record of how you actually experienced the cycle. Many people find the emotional log more valuable in hindsight than they expected, especially if they do future cycles.

Final Thoughts

Egg freezing is one of the most medically intense things a person can choose to do, and the right app depends on what part of the experience you most want help managing.

If you want the leading dedicated tracker, Berry Fertility has an egg freezing care path, medication barcode scanning, a stim phase calendar, and EMR integration where your clinic is a partner. If you want a free AI-first option and clinic comparison tools, Viva Fertility is worth trying. If community support during your cycle matters most, Glow has active fertility forums. If you already use Flo or Ovia and want continuity, both can layer onto your cycle, but neither has an egg freezing mode. And if you want to track the symptom, mood, sleep, and lifestyle side of your cycle alongside wearable data, Go Go Gaia handles the part dedicated treatment apps don't focus on.

A lot of people end up using two apps during their cycle: one for the medical protocol and one for the symptom and lifestyle side. That's a perfectly good approach. The important thing is keeping yourself organized and giving your future self a record you'll be glad to have.
