Full-stack monitoring for errors, metrics, and logs

seit. is a milestone tracker for iOS that does the math you wouldn't bother doing. Add an event — your first date, the day you quit smoking, your kid's birthday — and seit. continuously scans for special number-moments: palindromes (1001, 121), repdigits (111, 222, 333), Fibonacci numbers (1, 2, 3, 5, 8, 13, 21, 34…), round milestones, anniversaries, and weirder stuff like 1,000,000 minutes (≈694 days) or 10,000 hours (≈417 days). Built in SwiftUI / SwiftData / WidgetKit / StoreKit 2. iCloud sync, no account. Home & lock screen widgets. Apple Wallet passes for big days. Shareable events with a partner. German & English. Free for three events. Premium unlocks unlimited events, all milestone categories, every widget size, sharing, and Wallet.
