Everything you own has a cost beyond the price tag. Byebye tracks your items, calculates the true cost of ownership, and shows you patterns you'd never notice on your own. Add what you own, log when you use it, and watch your cost per use drop over time. Not a minimalism app. Not an inventory tracker. An awareness tool. TRACK YOUR STUFF Add items with a price and purchase date. Organize with categories, labels, collections, and spaces. Attach photos. Track as many items as you want — no limits. SEE THE REAL NUMBERS Cost per use. Daily carrying cost. Ownership score. Regret ratio. Dead weight. Spending trends by month and category. All calculated automatically from your real usage. LOG USAGE IN ONE TAP Tap +1 when you use something. That's the whole habit. Over time, your most-used items prove their worth — and your least-used items reveal themselves. CROSSING MOMENTS (Pro) When something meaningful happens — a regret pattern forming, a cost dropping, a streak building — Byebye notices and sends it to your lock screen. One moment a day, never noisy. SAY BYEBYE Ready to let go? Sell, donate, or simply archive. List items on the marketplace, chat with buyers, and track your in-vs-out trend over time. CONNECT WITH OTHERS Browse public inventories. Follow people whose approach to stuff inspires you. Share collections, spaces, and items — or keep everything private. PRIVACY FIRST You choose what to share. Delete your account anytime — we erase everything. Free to use. Byebye Pro unlocks Crossing Moments, unlimited collections and spaces, more photos per item, and a Pro badge.

The Saylo keyboard turns awkward into easy. Saylo is a smart reply keyboard for iPhone. It works inside iMessage, WhatsApp, Tinder, Hinge, Snapchat, Instagram, and every other chat app on your phone — no copying, no switching apps. When you don't know what to say, paste the message you got into Saylo's keyboard, pick a vibe, and tap one of three replies that actually sound like you. Better texts, right where you're already typing. REPLY ANYWHERE • Saylo Keyboard works in every chat app — generate without leaving the conversation • Paste text or upload a screenshot in the main app for longer threads • Conversation history syncs across both — continue where you left off VIBES THAT FEEL LIKE YOU Playful, flirty, witty, bold, caring, or just natural. Saylo doesn't make you sound like someone else — it picks up your tone and runs with it. GOALS FOR THE MOMENT Icebreak a new match. Continue a thread. Revive a cold one. Flirt. Banter. Go deeper. Pick the goal and Saylo shapes the replies. FRIENDLY FOR NON-NATIVE ENGLISH Built so your texts read naturally even if English isn't your first language. Non-native assist catches awkward phrasing before you send. 7 LANGUAGES English, 简体中文, 繁體中文, 日本語, 한국어, Español, Português. PRO MEMBERSHIP • Unlimited generations • All vibes unlocked • Permanent conversation history • Priority response speed $2.99 / month or $19.99 / year. Cancel anytime. Free tier: 6 generations per day. PRIVACY FIRST The Saylo keyboard never logs what you type into other apps. It only processes text you explicitly paste into the keyboard's own input bar. No tracking. No ads. Privacy policy: https://saylo.innofun.digital/privacy Terms: https://saylo.innofun.digital/terms

Verdict
The clearest difference is in-app purchases: Byebye at none against Saylo's 2. Byebye also leads on device support (3 vs 1). Saylo's advantage is update cadence (every 9 days vs every 3 weeks). On price, ads and iOS requirement there is nothing between them.
