The period tracker that never sees your data. No account. No cloud. No ads. Everything runs on your device. We built Perla after our wives got frustrated with trackers that sell data or blast ads. So we skipped the server entirely. The prediction engine, AI insights (Apple Intelligence), and fertility scoring all run locally. Apple Watch wrist temperature replaces expensive thermometers. Adapts to PCOS, endometriosis, pregnancy, and 8 birth control methods. $19.99/year or $49.99 lifetime.

Maptera helps you pin places that matter, organise them with tags and collections, and explore spots shared by others. Whether it's a cozy café, hidden beach, or playground, you’ll never forget a place again. Built with love by two brothers.

A beautifully simple round timer for MMA, BJJ, HIIT, and gym circuits. Built by two brothers. Custom presets, warning claps, and a horizontal mode with a big timer and edge progress. Fully offline, no ads, no accounts. FightClock is free forever.
