Cycling through all six. Tap any point to stop.

Measured on six things

SevenGrid shows your whole week on one screen. A missed day is an empty cell, not a broken streak. No account, no ads, pay once.

Growth

A real, named problem (streak guilt) with a cited study behind the fix, plus 'At most' goals and rest days that Streaks and Habitica structurally won't copy. Early — no iOS ratings yet, domain under a year old — but the wedge is genuine.

SevenGrid

About this app

SevenGrid is a calm, private habit tracker for iPhone and Android that shows your whole week on one screen. Every habit is a row, every day is a tap. There are no streaks: a missed day stays an empty cell instead of resetting a counter, and the next week starts fresh. Rest days for illness or travel and "at most" goals for things you want less of, like coffee or scrolling, are built in. Everything stays on your device: no account, no cloud, no ads. Free for up to three habits; a one-time purchase unlocks the rest, never a subscription. Available in English and German. Home screen widgets are available on Android. It is for people who gave up on habit apps because one missed day felt like failure, and for anyone who wants their habit data to stay on their own phone. Built and maintained by one person in Germany.

Key features

1Week-grid habit tracking with no streaks: a missed day stays an empty cell instead of resetting a counter.
2Rest days and 'At most' goals for reduction habits like coffee or scrolling, with soft grey feedback instead of red.
3Fully offline, no account, no cloud, no ads, no analytics — with complete CSV/JSON export of your data.
4One-time purchase unlocks unlimited habits; free tier covers three habits with no subscription.

Target customer profile

Drawn from the product itself, not from a survey.

Demographic

Busy professionals and parents (30–50) who have cycled through multiple habit trackers and abandoned each within weeks

Pain points

Streak guilt and reset anxiety; overbuilt dashboards that demand daily attention; subscription fatigue for a simple routine

Primary needs

A zero-friction weekly overview, missed days that don't punish, and a one-time purchase with no recurring fees

Demographic

Privacy-conscious Android and iOS users who avoid accounts, cloud sync and data collection

Pain points

Sign-ups, email collection and analytics trackers baked into wellness apps; unclear data policies

Primary needs

Fully offline operation, no account, transparent tracker scan, and complete CSV/JSON export of personal data

Demographic

Reduction-focused habit builders (quitting coffee, social scrolling, takeout) rather than 'do more' users

Pain points

Most trackers only reward hitting a daily target; overshoot is shown as failure in red

Primary needs

An 'At most' goal direction, soft grey feedback when over the limit, and weekly rather than daily framing

Demographic

Reflective self-improvers who enjoy journaling, mood logging and weekly reviews but dislike gamification

Pain points

Gamified streaks feel childish; journalling apps are separate from habit data; blank-page paralysis

Primary needs

A guided three-question weekly reflection, mood-and-active-days observation, and a year-at-a-glance tile view

Scout Review

Written by AI from measured evidence, scored out of 100.

SevenGrid is a habit tracker that removed the thing every other habit tracker is built on. No streaks, no counters, no red. A missed day is an empty cell and the week moves on. That's a genuine product thesis, not a marketing angle, and it's backed by a cited study rather than vibes. The execution matches: a clean week grid, twenty themes, eighteen colors, name-and-color onboarding, and a live demo you can tap before installing. The privacy architecture is the real differentiator — no account, no cloud, no analytics, full CSV/JSON export — and it's paired with a genuinely tight security posture on the site. The gaps are honest ones: touch targets too small for a tap-driven app, contrast failures, no accessibility statement, no published audit, and no cross-device backup beyond manual export. At 62 growth and 66 accessibility against 82 speed, this is a well-built indie product with a clear idea and a few fixable edges.

Measure by measure

Usability

Name-and-color onboarding means value in one tap, and the homepage demo lets you try the grid before installing. No account, no sync, no setup wizard. The trade-off is no cross-device restore — export is the only backup path.

Design

Judging the app UI from store screenshots and the live site demo: a disciplined week grid, 18 habit colors, 20 themes that carry through consistently. Calm, legible, and clearly ahead of Loop's utilitarian look, though not as crafted as Streaks.

Speed

Lighthouse mobile 94/100 with CLS 0 and TBT 0ms; desktop a clean 100. The only blemish is a 2.6s mobile LCP, just over the 'good' line, almost certainly the demo phone image. Snappy for a marketing site with a live interactive demo.

Security

Full 12/12 header and DNS checklist — HSTS, CSP, frame protection, SPF, DMARC all set. The offline, no-account architecture removes most breach surface entirely. No published audit, pen-test or bug bounty, which is normal at this stage but caps the score.

Accessibility

Lighthouse a11y 94/100 but three real failures: contrast, touch target sizing, and label/accessible-name mismatches — the last two matter a lot for a tap-a-cell app. Two languages shipped, no WCAG statement published.

Growth

Improvement areas

Touch targets and color contrast fail the accessibility audit — critical for a tap-driven grid interface.
No cross-device backup or restore beyond manual CSV/JSON export; a lost phone means lost history.
No published security audit, pen-test, bug bounty or security.txt despite a strong header posture.
No accessibility conformance statement or WCAG claim anywhere on the site.

Design & Usability

SevenGrid is judged on its app UI, not its landing page, and the app UI holds up: one row per habit, seven columns, a tap fills a cell. Eighteen colors and twenty themes that actually propagate through the interface rather than being a settings-page afterthought. Against Loop Habit Tracker's functional-but-plain Android look and Streaks' award-winning polish, SevenGrid sits comfortably in between — calmer than Loop, less precious than Streaks. Usability is where the philosophy pays off: onboarding is a name and a color, the homepage demo lets you tap before you install, and there is no account to create, no sync to configure, no wizard to dismiss. The cost of that simplicity is real — with no cloud, a lost phone means a lost year unless you exported. That's a deliberate trade, but it's a trade.

Speed & Security

The marketing site is genuinely fast: Lighthouse mobile 94 with zero total blocking time and zero cumulative layout shift, desktop a perfect 100. The one soft metric is a 2.6-second mobile LCP, just past Google's 'good' threshold, which points at the interactive demo phone as the heaviest asset — compressible, not structural. Security is the quiet strength. The HTTP probe returned a full 12/12: HSTS, CSP, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, plus SPF and DMARC on the domain. More importantly, the architecture does the heavy lifting — no account, no cloud, no ads, no analytics, habit data on-device. You cannot leak a database you never built. What's missing is the paperwork: no SOC 2, no pen-test summary, no bug bounty, no security.txt. For a one-person offline app that's an understandable gap rather than a red flag, but it's why this lands at 76 and not higher.

Accessibility & Growth

Accessibility is the weakest measured dimension and the failures are pointed rather than cosmetic. Lighthouse scores 94, but three audits fail: insufficient color contrast, touch targets that are too small or too tightly spaced, and visible text labels that don't match their accessible names. For an app whose entire interaction model is tapping small cells in a dense grid, the touch-target finding isn't a checkbox — it's the core gesture. Two languages ship (English, German), which is a real plus, but there's no WCAG conformance statement anywhere. Growth is the most interesting question. The problem is real and named precisely: streak resets make people quit, and the site cites Silverman and Barasch's 2023 Journal of Consumer Research paper to back it. The differentiators are structural — 'At most' goals for reduction habits, rest days that don't count as misses, a three-question weekly reflection — and Streaks and Habitica can't copy them without abandoning their core mechanic. Traction is thin (no iOS ratings yet, domain under a year old), but the wedge is real and the segments are specific.

Conclusion

If you've deleted three habit trackers because a broken streak made you quit, SevenGrid is aimed directly at you and it earns the shot. The one-time purchase and offline-only data model are the right answers to subscription fatigue and privacy anxiety respectively. Before you commit a year of habits to it, export once and confirm the CSV actually restores — that's the only real risk in the whole design. And if you're on Android with larger hands or a smaller screen, test the tap targets in the demo first; the audit says they're tight and the audit is probably right.

Suggestions for improvement

Increase touch target size and spacing in the week grid — the core gesture is failing its own accessibility audit.
Fix the contrast failures flagged by Lighthouse and publish a short WCAG 2.1 AA conformance statement.
Add an in-app reminder to export a backup, or an encrypted local file export, so a lost phone isn't a lost year.
Compress the hero demo asset to pull mobile LCP under 2.5s and close the last speed gap.
