Your Lock Screen should look like you. Themely lets you design the widget, pick the wallpaper, and match them - free, and entirely on your device. Most widget apps hand you a grid of presets and lock the good ones behind a subscription. Themely works the other way round: you build the widget yourself, everything is unlocked from the first launch, and there is nothing to buy. THREE STEPS 1. Design a widget - choose what it shows, then style it until it fits. 2. Save a matching wallpaper to Photos. 3. Follow the short in-app guide to place both on your screens. DESIGN YOUR OWN WIDGETS Build a widget instead of settling for a preset. Pick what it shows, then style it until it fits your screen: - Six widget types - Clock, Date, Photo, Countdown, Time Progress and Battery - Three sizes - small, medium and large - Twelve background styles and four type styles - Live preview while you edit, so you see the result before you save 72 WALLPAPERS THAT MATCH Every wallpaper is drawn on your device from twelve color palettes and six art styles: Mesh, Waves, Rings, Grid, Blobs and Linear. Browse by mood - minimal, pastel, gradient, abstract or dark - and save any of them to Photos at full 1290 x 2796 resolution. No watermark, no export limit. TWELVE THEME PACKS A theme pack pairs a wallpaper with a matching widget style, so your Lock Screen and Home Screen agree with each other. Apply one and Themely walks you through both steps. BUILT FOR HOW iOS ACTUALLY WORKS iOS does not let any app place a widget or change your wallpaper for you. Themely does not pretend otherwise - it saves your design, then shows a short, clear guide for the two steps you do yourself. No shortcuts to install, no profiles to trust. PRIVATE BY DESIGN Themely has no ads, no analytics and no third-party SDKs. Your widgets, favorites and settings stay on your device, and a photo you pick for a Photo widget never leaves your phone. We collect nothing. WORKS OFFLINE All artwork is generated on your device, so the whole library works with no connection and the app stays small. NO ACCOUNT, NO SUBSCRIPTION No sign-up, no email, no free trial that quietly renews. Open the app and everything is already there. QUESTIONS Can Themely set my wallpaper for me? No - iOS reserves that step for you, and any app that claims otherwise cannot deliver it either. Will my designs sync between devices? No - everything is stored locally, which is the same reason nothing is ever sent anywhere. Is it really free? Yes. No paid tier, no in-app purchase, no trial. Requires iOS 17 or later.

Verdict
The clearest difference is iOS requirement: EnerKey at 12.0 against Themely's 17.0. On price, ads, in-app purchases and device support there is nothing between them.
