I Copied A Huge App. Now I Make $80K/Month

Tomer, a former marketer, built Cal Buddy, a Hebrew AI calorie tracker modeled on Cal AI, for the Israeli market using Cursor (about two months to App Store). Launched June 2025 at ~$1K/month, it reached ~$20K/month in four months via paid ads with creatives modeled on viral US-app and Israeli fitness content, then ~$81K/month by April 2026 after a revenue-share partnership with a well-known Israeli fitness influencer covering all Israeli revenue.

Rebuild a hit US app in Hebrew for Israel, where no one offers it

$1K first month to $81K/month within about 10 months

After hearing Cal AI's founder describe scaling to $1M+/month, the founder rebuilt the same core experience (photo a meal, get calories and macros) for Israel: Hebrew language plus small changes to fit how Israelis eat and talk about food. Rule used: in a small market the niche must be huge, so he picked fitness/nutrition, a niche he knew personally. He treats brand and distribution, not product, as the real differentiator. Built with Cursor (working version in 2 weeks, live in ~2 months).

Copy the most viral content from similar US apps and local fitness creators into ads

About $20K/month within four months of launch

Chose paid ads as the main channel because Israeli CPMs are much lower than US, so ads can be profitable without much testing budget. Studied the most viral content from similar apps in the US and the most viral fitness/nutrition content in Israel, then made ad creatives based on those and ran them in ad campaigns.

Give big fitness influencers a cut of revenue instead of paying per post

Took revenue from $20K to $80K+ a month

Waited until the app made ~$20K/month from ads so he had social proof and happy users, then approached big influencers (paying per story/reel would cost a fortune). Signed a revenue-share deal covering all revenue from Israel with a well-known fitness figure he knew personally; the traction let him negotiate terms better than 50-50. The contract is built on work timelines: a set number of content pieces and filming/recording days per month. The partners become the faces of the brand, making it harder to copy.
