When do I insert my birth control ring? When do I remove it? When is my next ring change? Ring - Birth Control Tracker is a contraceptive ring tracker, vaginal ring reminder, medication tracker, and cycle calendar designed specifically for people who use a hormonal contraceptive ring for birth control and pregnancy prevention. It calculates your upcoming insertion and removal dates automatically, so you always know where you are in your current cycle and when your next change is due. No counting days. No wondering whether you forgot to take it out. No missed ring change because life got busy - just more confidence that you’re staying on schedule with your contraceptive routine and using your ring as intended for pregnancy protection. SET UP YOUR RING SCHEDULE Choose how many days you keep your vaginal ring in and how many ring-free days you have, then enter the date and time you inserted it. The app builds your cycle and tracks upcoming changes automatically. Follow a routine of three weeks in and one ring-free week, use your ring continuously with no break, or create a custom contraceptive schedule. If your prescribed routine changes, update it at any time. Because the schedule is customizable, the app can adapt to different contraceptive ring routines instead of being locked to a single fixed schedule. INSERTION & REMOVAL REMINDERS Stay on top of your contraceptive schedule with: • Insertion reminders to help you put in a new ring on time • Removal reminders so you know when it’s time to take it out • Upcoming ring change dates • Current cycle status at a glance Your insertion and removal history is saved, so you can check when you last changed your ring and review previous cycles. CONTRACEPTIVE RING CALENDAR See your complete contraceptive schedule in one cycle calendar: • Days with your ring inserted • Ring-free days • Upcoming insertion and removal dates • Previous cycles • Notes added to individual days BUILT FOR THE BIRTH CONTROL RING A vaginal ring isn’t a daily pill. Instead of adapting a general period tracker, medication reminder, or pill tracker to your contraceptive method, you get a cycle tracker and contraceptive reminder built specifically around the vaginal contraceptive ring. Whether you’re new to hormonal contraception or have used a contraceptive ring for years, it’s one dedicated place for managing your ring routine with confidence. FREE FEATURES • Insertion and removal reminders • Contraceptive ring cycle tracker • Cycle calendar and current cycle overview • Insertion and removal history • Notes for individual days PREMIUM FEATURES • Custom notifications - choose when your reminders arrive and their sound • Home Screen widgets - check your current status without opening the app • Personal diary - keep notes throughout your cycle • Symptom tracking - log bleeding, menstrual symptoms, side effects, and how you feel • PDF report - export your contraceptive history to share with your healthcare provider or gynecologist YOUR DATA, YOUR PRIVACY Your contraceptive tracking data stays on your device and is not shared with third-party analytics services. IMPORTANT Ring - Birth Control Tracker is a reminder, calendar, and tracking tool. It does not provide medical advice, diagnosis, or treatment. Always follow the instructions provided with your contraceptive ring and the guidance of your healthcare professional. SUPPORT Questions or feedback? Contact us at birthcontrolring@gmail.com.

Verdict

The call

The clearest difference is in-app purchases: Catchtrial ePro at none against Ring's 4. Catchtrial ePro also leads on ads (none vs shown) and rating (5.0 vs 4.7). Ring's advantage is ratings volume (32 vs 1) and update cadence (every 3 weeks vs every 2 months). On price there is nothing between them.
