Decoy
Read full descriptionHide full description
The iPhone's own Notes app can't live on your Lock Screen. Decoy can, and nobody else can read it. Appointments, medication, errands you'd rather not explain. The Lock Screen is the surface you glance at most, and it's also the one other people see most. So some things never made it there. While your phone is locked, Decoy looks like a blank card, or whatever text you chose in advance. The moment Face ID passes, your real notes appear. ■ Made for ・Writing things down and then never looking at them again ・Living or working around people who glance at your screen ・Appointments and errands you'd rather keep to yourself ■ What it does ・Works as a to-do list, or as plain notes ・Reminders at the time you set ・Repeats daily, on weekdays, weekly, monthly ・Separate lists for separate parts of your life (Pro) ■ How it's built ・No ads ・Everything stays on your device by default. iCloud sync is there if you want it ・No accounts, no sign-in A note on what this is not: once Face ID or your passcode has been entered, anyone holding your phone can read your notes. Decoy hides things from the people around you, not from someone with your unlocked phone. Keep passwords and PINs in a dedicated password manager. Decoy Pro is a one-time purchase. It removes the note limit and adds per-note reminders, separate lists, and control over how things look while locked.

Chigiri Memo

Write it all down first. Split it later. Simple to use, with everything you need in one notepad. Card-based note apps make you decide where something goes before you write it. Split Notes works the other way round: you write onto one page, and split out what you need afterwards. Filing becomes a decision you can postpone. ■ A cut line marks where a block ends Tap "Insert cut line" in the footer and a dotted line appears wherever the cursor is. The Copy / Share and To delete buttons sit just above each line, and they act on the block above that line only. Press and hold a line to remove it, and the blocks above and below become one again. ■ Tabs instead of folders Each tab holds one continuous page, so everything you wrote earlier stays in view while you type. Press and drag a tab to reorder it: gather the ones you use on the left, and the rest slide off the edge of the screen. Nothing is deleted, so scroll sideways and they come back. The order is the filing. ■ Move the cursor without opening the keyboard You can select text without the keyboard popping up every time you touch the page. Tap the strip along the right edge when you want to write. While the keyboard is up, the Insert cut line button floats just above it, so you can split what you wrote without stopping. ■ We tell you when you repeat yourself Press Search all and the app points out passages you wrote twice within the same tab. Tap a row to jump to the note, with both places lit up in yellow. If it turns out you need both, choose "Don't show" and that pair stops appearing. ■ Also included - Full-text search across every tab, with the match lit up in yellow - Earlier versions: the last 30 are kept for each tab - Pinch with two fingers to resize the text; the size you choose is remembered - Screen lock: swipe the right-edge strip to the left to cover the text. Unlock with Face ID / Touch ID, or your device passcode - Dark mode - A double tap selects a whole alphanumeric run, so 1234-5678, user_name and email addresses are not cut in half ■ Your notes never leave your device What you write is stored only in a database on your iPhone. There is no mechanism for sending it to our servers, and there is no account and no sign-in. The screen lock covers what is on the screen. It is not a vault that encrypts the text itself, so please use a dedicated password manager for anything that needs that level of protection. ■ Price Every feature is there from the start, free. Tabs, cut lines and full-text search are unlimited, and the screen lock and dark mode work as well. The only difference is whether ads appear. Removing them is a one-time purchase, not a subscription.

Verdict
The clearest difference is ads: Decoy at none against Chigiri Memo's shown. Chigiri Memo's advantage is iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.
