GainBlocks
Read full descriptionHide full description
You train, but you can't tell if it's enough. GainBlocks makes it countable. Every muscle gets a weekly target in hard sets. Every hard set you log fills one block. Fill your board before Monday, on whatever days you train. A READY SESSION EVERY TIME Open the app and start the next session. GainBlocks builds your week from the days you train: full body, upper and lower, or push, pull and legs. Same lifts in the same order, with sets, weight and reps, so you can beat last time. NO FIXED DAYS TO FALL BEHIND ON A session is never tied to a weekday and there are no missed workouts. Just blocks still open. Train Tuesday and Saturday or five days straight; the board keeps score either way. A TARGET FOR EVERY MUSCLE Tell it how often you train and which muscles you want to bring up. GainBlocks sets a weekly number for chest, back, shoulders, arms, legs and abs, with extra work where you asked for it. ONE SET CAN FILL MORE THAN ONE ROW A bench press fills a chest block and adds half a block to shoulders and triceps. You see where your week is ahead and where it is behind. IT REMEMBERS YOUR NUMBERS Open an exercise and you see what you did last time and what to take today. Beat it and the next target moves up. LOCK IN BEFORE EVERY SET Hold to lock in, then give the set everything. Log your reps, say how much you had left, and the block lands. OR DO YOUR OWN THING Tap any muscle on the board and train that instead. It all counts. Short on time? Say how long you have and GainBlocks lines up the exercises that close the biggest gaps. RECORDS GET THEIR MOMENT A new best gets a plate slam and your number in yellow. No ads. No social feed. Your training data stays in your account. SUBSCRIPTION GainBlocks offers an auto-renewable subscription with a 7-day free trial. Payment is charged to your Apple ID and renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Sproutkin is a simple, private baby activity tracker built for new parents who want to stay organized without signing up for another account or handing their data to the cloud. TRACK WHAT MATTERS, IN ONE TAP Log feeds (breast, bottle, formula, or solid food), sleep, diapers, vitamins, baths, walks, tummy time, and temperature — plus any custom activity you define. Durational activities like sleep start a timer on tap and stop it on the next tap. SHARE WITH YOUR CO-PARENT, NO CLOUD NEEDED Sproutkin lets multiple caregivers merge logs without any account. Export a .sproutkin file and share it with your partner however you like — AirDrop, iMessage, email. Their app merges it in; both logs stay up to date. FEED TRACKING THAT REMEMBERS THE DETAILS Log nursing sessions and Sproutkin remembers which side was last used, so whoever picks up the next feed always knows where to start. Log solid foods by name and mark any reactions; the Analytics tab keeps a full history of every food introduced and any that caused a response. SLEEP ANALYTICS THAT GO DEEPER Three dedicated sleep cards: total sleep per day, estimated bedtime (derived from your logged sessions), and night stretches — so you can see at a glance whether sleep is consolidating into longer blocks. Customize which analytics cards appear and drag them to your preferred order. SUPPLIES, NOT JUST ACTIVITIES Track when you open a new can of formula, a diaper pack, or wipes. The Consumables tab shows how long your current container has been open and the average lifespan of past ones — a practical heads-up for when to reorder. REMINDERS Set notifications for any activity — a daily vitamin reminder, a feeding window, anything you need. No account required; uses your device's notification system. YOUR DATA STAYS ON YOUR DEVICE Everything is stored locally using Apple's SwiftData framework. No cloud sync, no analytics SDKs, no ads, no subscription. Back up or share your data at any time via a .sproutkin export from Settings.
