Quick answers
How do I run a skin scan?
Tap Scan on the home screen, line up your face inside the on-screen guide in good, even lighting, and tap the shutter. Your detailed report appears within a few seconds.
My scan score seems off
Skin scans are sensitive to lighting. For the most consistent results:
- Use bright, natural daylight or a soft white indoor light.
- Avoid direct yellow or blue tinted lights.
- Remove makeup before scanning if possible.
- Hold the phone at eye level, about 30 cm away.
Can I trust the results?
Our scoring is based on visual analysis, not a medical diagnosis. Use it as a way to track changes in your own skin over time — that's where it shines. If you're worried about a specific condition, please see a qualified dermatologist.
Does TwachaLens work for all skin tones?
Yes — TwachaLens is calibrated across all six Fitzpatrick skin types and is tuned for Indian skin tones in particular.
How do I delete my data?
Open the app → Settings → Account → Delete Account. This permanently removes your scans, profile, community posts, and all photos saved on your device. The action is immediate and cannot be undone.
How do I change my routine reminders?
Settings → Notifications. You can pick the morning and evening times, water-reminder schedule, and how often to nudge you for your next scan.
I forgot my password
On the Sign In screen, tap Forgot Password. Enter the email you signed up with and follow the prompts.
How do I report or block someone in Community?
Long-press any post or comment in the Community feed → tap Report to flag it, or Block to hide that user's posts and comments from your feed. Reported content is hidden from your view immediately and reviewed by our team. You can manage blocked users in Settings → Privacy → Blocked Users.
Sign-in with Apple shows a strange email
That's intentional — Apple's "Hide My Email" creates a private relay address. Mail to it forwards to your real Apple ID inbox. You can manage these relays in iOS Settings → Apple ID → Sign in with Apple.
I'm not getting my routine reminders
- iOS notifications are allowed: iOS Settings → TwachaLens → Notifications → Allow.
- The reminders themselves are switched on inside the app: Settings → Notifications.
- Focus / Do Not Disturb isn't blocking them.
If they're still not arriving, email us with your iOS version and we'll dig in.
Do you sell my data?
No. We do not run ads and we do not sell or share personal information for marketing. See our Privacy Policy.
