Antamio

One small challenge. A little company. Progress you can see.
Choose something you want to keep doing, set your pace and invite someone along. Antamio gives each effort a place: today's check-in, your shared activity and the days you kept.

MAKE IT YOURS
Start with a seven-day plan or create your own challenge, from 3 to 365 days. Track reps, minutes, manually entered steps or a simple check-in. Choose daily sessions or planned rest days. Hold today's tile or tap Complete; smaller amounts count toward your target. Offline check-ins sync when you reconnect. Set reminders for the time that suits you.

SHARE THE EFFORT
Invite a friend or start a private group with one link. Share an activity, schedule and finish line. Each person can choose their own amount, unless the creator sets one target for everyone. See shared progress and cheer with reactions. Phone notifications depend on permission; they never include your private notes, progress photos or weight.

SEE YOUR RHYTHM
Open My stats for weekly sessions, streaks and effort totals. Explore Trends for a closer look: Free shows the last 30 days; Plus adds longer periods up to a year and advanced insights. Optional weight tracking stays private.

KEEP SOMETHING TO LOOK BACK ON
Make progress and final cards, with photos or without. Optional before-and-after photos can become a reveal video. Restart a finished or abandoned challenge when you're ready for another round.
A Streak Shield can cover a missed day; Strict groups do not use shields.

FREE AND PLUS
Free includes up to 3 of your own active challenges, solo or shared, hosting groups of up to 20 people including you, 30 days of detailed history and one Streak Shield per challenge. Joining invitations is free and unlimited; joined challenges do not use your own-challenge allowance.
Plus adds unlimited own active challenges, hosting groups of up to 50 people each, including you, full detailed history, advanced Trends, weekly Streak Shield renewal and timelapses of daily photos.
Progress cards, reveal videos, friend invitations and restarting finished or abandoned challenges are included in both plans.

Plus is a monthly or yearly auto-renewing subscription through Google Play. Your local price is shown before purchase. Payment is charged through your Google Play account. Subscriptions renew unless canceled. Manage or cancel in Google Play under Payments & subscriptions.

YOUR PHOTOS, YOUR CHOICE
Photos are optional. Daily photos stay on your phone; before-and-after photos are stored privately in your account. You choose what to export or publish. Group members see shared daily progress, never your private notes, progress photos or weight. Challenge instructions, images and video links are shared with participants and, for published public challenges, through discovery. Reporting, blocking and account deletion are available in the app.
