HyNext. Built for muscle growth. No more working out how much to add next time. HyNext looks at how many reps you actually did in every set and plans your next weights and reps.

Free ・Generates a program from your training experience, body type and the look you want, your goal, available equipment and training days per week ・Log every set, exercise library with how-to guides, history and personal bests ・Optional sign-in and cloud backup, so your training log comes with you to a new phone Full version (all features free for the first 14 days, counted from the first time you open the app, no payment needed) ・Decides after every workout whether to add weight, hold or drop ・Gives you a little more rest when your reps drop too much between sets ・Explains why you are stuck and what to do next, not just "keep going" ・Adds sets in small steps during a muscle-gain phase, and watches for two weeks after each increase before asking again; suggests a deload when recovery can't keep up ・Make up or skip missed sessions ・Weekly reports, a yearly review, body weight and per-exercise trends ・The evidence and studies behind every recommendation No ads. HyNext full version is an auto-renewing subscription: ・Monthly NT$150 / month ・Yearly NT$1,000 / year ・These are early-bird prices; the actual price and currency are shown in the App Store ・Payment is charged to your Apple ID account when you confirm the purchase ・The subscription renews automatically unless cancelled before the end of the current period; you can manage or cancel it any time in your App Store account settings Privacy Policy: https://hynext.space-yuan.com/docs/legal/en/privacy-policy.md Terms of Service: https://hynext.space-yuan.com/docs/legal/en/terms.md
SipFlow

SipFlow turns drinking water into a tiny daily ritual with a friend. Remember the pocket pets of the 90s? Your droplet buddy is a tiny virtual pet that levels up as you drink water. Name it, take a sip, tap. It wobbles, splashes and smiles, and your day fills up one sip at a time. No measuring cups, no typing numbers. TAP AFTER EVERY SIP • One tap logs one sip, sized to you from your answers during setup • Undo in a tap if you pressed by accident • A gentle daily goal you can change any time A BUDDY THAT GROWS WITH YOU • 13 levels with a gift on every new one • Pet your buddy, dress it up with accessories and colors • Mini-games that never log water BATTLE WITH FRIENDS • Send a friend your code and see who drinks more water today • Get a nudge when a friend starts drinking or pulls ahead • Every morning, find out who won yesterday • No sign-up, just a name. Leave and delete your battle account any time STREAKS WITHOUT GUILT • A day counts as soon as you take one sip • New buddy colors at 3, 5, 7, 14 and 30 days in a row • Share a streak card with a friend • Missed a day? Just start again, no scolding ALWAYS AT HAND • Home Screen and Lock Screen widgets with a sip button • Live Activity on the Lock Screen and in the Dynamic Island • Friendly reminders at the hours you choose • A calendar of past days SIPFLOW PLUS Plus adds rescue days (two a month, so a missed yesterday doesn't break your streak), three more games (Lily Jump, Little Drops 2048 and Catch the rain), the Apple Watch app, Live Activity, coffee colors and the pink bow, and unlocks gift colors right away. Choose Monthly, Yearly (first week free) or Forever, a one-time purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in Settings › Apple Account › Subscriptions. PRIVATE BY DESIGN No ads, no analytics, no tracking, no sign-up. Your data stays on your device; the battle shares only your name, your buddy and today's water with friends you add. SipFlow estimates intake from taps. It doesn't measure what you drink and isn't medical advice.
