Track the habits that matter and finally make them stick. Habit Tracker turns scattered good intentions into structured daily routines you actually complete — one step at a time. Most habit trackers give you a checkbox and hope for the best. This one gives you a real routine: build a sequence of tasks, schedule it on the right weekdays, run it step by step on a guided screen, and grow a streak you do not want to break. WHAT YOU GET - Build multi-step routines with custom icons, colors, and tags for your morning, work, and evening flows - Keep momentum with active streaks and an evening alert before a streak breaks - See exactly how you are doing with completion rates, a calendar heatmap, and 30-day trends - Get automatic insights that reveal your best days and where habits slip - Start in seconds with ready-made templates like Morning Energizer, Deep Work Block, and Evening Wind-down - Set goals linked to your routines and watch a progress ring fill as completions add up PERFECT FOR - Anyone building a consistent morning or evening routine - Students and professionals structuring focused work blocks - People rebuilding discipline after falling off track - Habit trackers who want streaks plus real stats, not just checkboxes WHY NOT JUST USE A CHECKLIST APP? A plain checklist tells you what to do but not whether it is working. Habit Tracker schedules your routine, walks you through it task by task, saves partial progress if you step away, and turns every completion into streaks, heatmaps, and trends — so you can see your consistency grow instead of guessing. PRIVACY Everything is stored on your device. No account, no cloud sync, no ads, and nothing to sign up for. Your routines and progress stay with you.

Erre is a to-do list built around projects instead of dates. Most task apps ask when something is due. Erre asks what it belongs to. Your to-dos live inside a project; that could be a shoot you are editing, a room you are cleaning, a trip you are getting ready for. Everything is accessible on one screen and extremely easy to navigate. WHAT IT DOES • Create, rename, reorder, and archive projects easily. The one you are working on fills the screen. • Drag to reorder. Swipe to delete. Tap to tick. • Completed to-dos sink to the bottom, struck through, and can be hidden entirely. • The line above each project name writes itself; "new", then "in progress", then "completed" as the work moves. Type your own label instead and Erre leaves it alone. • An archive for the projects you have finished, and a restore button for the ones you had not. • Four accent colors and two densities. ON IPAD AND IPHONE DUO On an iPad, or an iPhone Duo opened flat, Erre becomes a notebook laid open: a contents page of every project on the left, and the one you are working on facing it. On the closed Duo, the side column takes your accent color and holds the tools: add, projects, completed, and settings. Your list fills the rest of the screen. WHAT IT DOES NOT DO No account. No sign-in. No notifications, no streaks, no nagging, nothing to subscribe to. It also does not talk to the internet. There is no networking in the app at all — your projects and to-dos are written to a single file on your iPhone and they stay there. Nothing is collected, nothing is measured, nothing is sent anywhere. HOW IT LOOKS Erre is set in the manner of a printed field notebook: warm paper, a double rule under the header, monospaced small caps for the labels, and a serif where it counts. It is meant to look like something you would write in, not a dashboard.

Verdict
The clearest difference is in-app purchases: Erre at none against Routine Builder's 3. Erre also leads on update cadence (every 4 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
