Sometimes, you just need to say something out loud so you can finally let it go. That’s exactly what Mountaintop is for. This isn't a voice memo app, and it’s not meant for saving your big ideas. Instead, it’s a simple, mindful space designed to help you dispel distracting, crowding thoughts by getting them out of your head. The experience is simple and physical: - Hold to speak: Voice whatever is cluttering your mind. - Release when ready: Let go of the screen when you've said what you need to say. - Tilt & exhale into the mic: Physically blow your words away. Watch them shatter into paper particles and float off into the mountain wind. When you're done, there is no success pop-up, no saved audio file, and no history log. The screen simply returns to a peaceful view, leaving you with (hopefully) a little less noise in your head. I built Mountaintop in my spare time just for the fun of learning and creating something peaceful. The app is completely free to use. If you find it helpful, relaxing, or just a nice way to clear your head, there is an option to leave a small tip in the settings - but ultimately I really just appreciate you trying it out. I hope it helps bring a little more quiet to your day.

Every feature free. No subscription. No data sharing. Ever. Many period apps charge $10 to $15 a month, and some have been caught sharing reproductive health data with advertisers. Iris keeps your cycle data on your iPhone: no Iris servers, no account, no analytics. Your health data is never shared or sold. PERIOD & CYCLE TRACKING Log your period and Iris predicts your next one, your fertile window, ovulation day and PMS phase, mapped out weeks in advance. Color-coded calendar, day log and smart reminders included. HOME & LOCK SCREEN WIDGETS See your cycle day, phase and days until your next period at a glance, right on your Home Screen or Lock Screen. IRREGULAR CYCLE TRACKING Iris detects cycle variability from your data and switches to honest prediction ranges instead of single dates. No fertile window guessing for irregular cycles. Built for PCOS, perimenopause and anyone whose body doesn't fit the textbook. PERSONAL INSIGHTS & PATTERN DETECTION Iris turns your daily logs into useful patterns. See which symptoms, moods, discharge types, activity and vitals appear most often in each cycle phase, then tap into any pattern for phase distribution, cycle-day timing, recent history and prediction notes. After enough history, Iris can help you spot recurring signals like fatigue, cramps, mood shifts or discharge changes before they appear, with insights calculated privately on your device. LH STRIP LOGGING Log your daily ovulation test result: Negative, Positive or Peak. Iris immediately shifts your ovulation estimate to reflect your actual LH surge. Over time, Iris learns your personal luteal phase length and uses it to sharpen every future prediction, replacing the generic 14-day default with your actual biology. BBT TRACKING Log your basal body temperature each morning and Iris calculates your personal coverline. When three consecutive readings rise above it, Iris marks a confirmed thermal shift: retrospective confirmation that ovulation occurred. Pair BBT with LH strips for the symptothermal method, completely free. APPLE HEALTH SYNC Two-way sync with Apple Health. Iris reads your period history, BBT from connected thermometers, sleep and weight. Period days, BBT, LH results and cervical mucus are written back to your Health dashboard. What you log in Iris always wins; Apple Health only fills days you haven't logged. CONTRACEPTIVE & POSTPARTUM MODE On the pill, a hormonal IUD or a copper IUD? Contraceptive Mode pauses ovulation predictions, labels bleeds as withdrawal bleeds and adds a daily pill reminder. Just had a baby? Postpartum Mode pauses predictions while you recover, then resumes when you're ready. SYMPTOM & MOOD TRACKING Log mood, 14 symptoms (cramps, bloating, fatigue, acne, brain fog, hair shedding and more), discharge type with fertility context, sleep, weight and notes for any day. HORMONE EDUCATION Visualize estrogen, progesterone, FSH and LH across your full cycle, mapped to your own cycle length so the chart reflects your actual rhythm. PARTNER SHARING Invite a partner to follow your cycle: view-only, end-to-end encrypted and completely free. PRIVATE BY DESIGN Your data stays on your iPhone. No Iris servers. Optional iCloud backup goes to your own iCloud account, and we never see it. No analytics or tracking SDKs. The free version shows ads, which never receive your health data; a one-time purchase removes them. 100% FREE, NO EXCEPTIONS No premium tier. No subscriptions. No paywalls. Every single feature, from LH logging and BBT charting to irregular cycle detection, Apple Health sync, widgets, contraceptive mode and postpartum mode, is free for everyone, forever. Download Iris. Your cycle is yours.
