Requirements

Streak Milestone Detection
"As a TipJar professional, I want the app to accurately detect my streak milestones so that I can unlock new themes automatically as I maintain consistency."
Description

Implement a backend system that accurately tracks and records consecutive usage streaks for each TipJar user by integrating with activity logs. The system should detect when users reach predefined streak milestones (e.g., 7-day, 14-day streaks), ensuring reliability and scalability. It must trigger downstream processes for theme unlocking automatically upon milestone achievement and maintain an audit trail of detected streaks for reporting and analytics.

Acceptance Criteria
User Achieves 7-Day Streak
Given a user has logged activity for seven consecutive calendar days, when the nightly streak detection job runs, then the system records a 7-day streak milestone for that user in the database.
User Achieves 14-Day Streak
Given a user has logged activity for fourteen consecutive calendar days, when the nightly streak detection job runs, then the system records a 14-day streak milestone for that user in the database.
Activity Logging Integration
Given the activity logging service emits events for each user action, when the backend ingests these events, then all events within the past 24 hours are available for streak calculation without data loss or duplication.
Downstream Theme Unlock Trigger
Given a streak milestone is recorded, when the milestone is saved, then the system automatically enqueues a theme unlock event to the theme service queue with the correct user ID and milestone type.

Admin Uploads Theme Preview Assets
Given an existing theme entry, when the admin uploads preview images or videos in supported formats and within size limits, then the system stores the assets, links them to the theme preview, and displays thumbnails in the theme list.
Admin Filters Themes by Category and Tag
Given multiple themes with assigned categories and tags, when the admin applies a category or tag filter, then only themes matching the selected filter criteria are displayed in the repository.
Admin Manages Theme Versioning
Given a theme has published versions, when the admin creates a new version update, then the system increments the version number, archives the previous version, and makes the latest version available for assignment to user profiles.
Automatic Theme Unlock Logic
"As a TipJar user, I want to have new themes unlocked automatically when I hit streak targets so that I can personalize my profile without manual intervention."
Description

Create backend services and APIs that link detected streak milestones to specific theme unlock rules. The logic should evaluate user eligibility based on their current streak, assign the corresponding theme unlocks to the user profile, update permissions, and log unlock events. Ensure the service is performant, secure, and resilient to concurrent requests.

Acceptance Criteria
Milestone Theme Assignment Trigger
Given a user with a 4-day streak, when the user completes a qualifying transaction to reach a 5-day streak, then the backend service evaluates eligibility, assigns the “5-Day Streak” theme to the user profile, returns a 200 OK response with the updated theme data, and updates the user’s permissions accordingly.
Concurrent Unlock Request Handling
Given multiple simultaneous requests for the same user streak milestone, when the backend service processes these requests, then it ensures only one theme unlock event is created, avoids duplicate theme assignments, and returns consistent success responses without errors.
Permission Update Verification
Given a user who has unlocked a new theme, when the user fetches their profile settings, then the new theme appears in their available themes list, and attempts to apply the theme succeed without permission errors.
Unlock Event Logging Validation
Given a theme unlock action, when the backend logs the event, then the audit log entry includes userId, streakMilestone, themeId, timestamp, and requestId, and the entry is persisted in the audit log database within 2 seconds.
Service Performance Under Load

TipJar Introduces StreakSpark Reward System to Boost Daily Tipping by 15%

Imagined Press Article

NEW YORK, 2025-06-20 – TipJar, the leading automated digital tipping platform for independent salon and café professionals, today announced the launch of StreakSpark, a dynamic new reward system designed to ignite daily tipping streaks and drive average tip volume by at least 15% per service. StreakSpark leverages TipJar’s proven behavioral insights and gamification mechanics to deliver vibrant reward badges, custom profile themes, and one-time-use boosters when users maintain consecutive days of cashless tipping transactions. The tipping landscape has evolved rapidly in recent years. Independent stylists, baristas, and mobile professionals increasingly rely on cashless interactions, but many still miss out on incremental earnings due to inconsistent tipping habits. StreakSpark addresses this challenge by turning everyday gratuity into a compelling, game-like experience. Professionals earn visual badges and unlock exclusive page themes the moment they complete each day’s tipping activity, reinforcing retention and encouraging continued engagement. Key benefits of StreakSpark include: • Consistent Earnings Growth: Early pilot programs demonstrated a 15% increase in average tip values among professionals maintaining a five-day streak. • Motivational Badges: Unique, tiered badges are awarded for milestone streaks (3, 7, 14, 30 days), each with a distinct visual to showcase progress and dedication. • Custom Profile Themes: Unlockable themes allow users to personalize their TipJar pages with branded colors, backgrounds, and fonts—enhancing memorability for repeat customers. • Streak Boosters: Professionals earn one-time-use boosters at critical streak points, enabling them to protect a day from breaking their streak or doubling badge progress for even faster rewards. “StreakSpark represents a major step forward in our mission to empower service professionals,” said TipJar Founder and CEO Jane Mitchell. “By combining behavioral psychology with powerful gamification, we are transforming tipping from an afterthought into an engaging habit. Our users tell us that StreakSpark not only boosts their earnings but also deepens their connection with customers, who enjoy the colorful badges and personalized themes.” StreakSpark is built upon TipJar’s existing framework of seamless digital payout, real-time analytics, and intuitive one-tap payment pages. Once users opt into StreakSpark within the TipJar app, they see a visual streak counter on their dashboard, receive in-app reminders to maintain momentum, and instantly claim badges at streak milestones. All progress is visible in the new Streak Timeline feature, allowing professionals to look back on achievements and share their streak snapshots to social media. “We implemented StreakSpark across our flagship studios last month and the results have been remarkable,” said Mentor Mia, a senior salon educator and early adopter. “My trainees were thrilled to see every day’s streak rewarded with something tangible. Not only did tips increase, but customer feedback highlighted how much they appreciated the fun, personalized themes on our pages.” TipJar’s integrated StreakReminders ensure professionals never miss a day. Customized push notifications and in-app prompts trigger at optimal times—before opening doors or during scheduled breaks—so users can keep their streak alive without fuss.

TipJar Launches Leaderboard Live to Fuel Friendly Competition and Uplift Tips During Peak Hours

Imagined Press Article

SAN FRANCISCO, 2025-06-20 – TipJar, the industry-leading digital tipping solution for independent salon and café professionals, today unveiled Leaderboard Live, an innovative feature that displays real-time tipping rankings on salon and café screens to spark friendly competition and increase tip volume by up to 10% during peak service hours. Leaderboard Live integrates seamlessly with TipJar’s existing systems to provide dynamic, customizable leaderboards that reinforce high performance and foster team camaraderie. As service professionals juggle high customer volumes, recognition and motivation can wane. Leaderboard Live addresses this gap by celebrating top earners, tracking individual and team performance, and creating timely, engaging moments that drive additional tips. The feature is particularly effective during busy lunch hours in cafés and pre-event rushes in salons, when a visual push can turn a good shift into a great one. Key elements of Leaderboard Live include: • Real-Time Rankings: Live updates of tip totals for individuals and teams, with flexible views by hour, day, week, or service category (e.g., haircuts vs. color treatments). • Custom Brackets: Managers can tailor leaderboard parameters to highlight specific performance windows—like morning rush, happy hour, or weekend brunch—providing targeted insight and motivation. • Spotlight Moments: Whenever a professional enters the top three, the system triggers on-screen animations and branded banners to immediately recognize achievements and energize the floor. • Team Challenges: Salons and cafés can set up collaborative or competitive events where staff members or groups battle for the highest cumulative tip total, unlocking exclusive group themes and rewards. • Social Streamer: Automatic generation of on-brand snapshots optimized for Instagram Stories, Facebook, and TikTok further amplifies staff accomplishments and attracts new clientele. “Competition is a powerful motivator, and Leaderboard Live brings that energy directly to the team in a fun, transparent way,” said TipJar Chief Product Officer Alexandra Reyes. “We’ve already seen an average 10% uplift in tip volume in our beta locations. Professionals love the immediate recognition, and managers appreciate the actionable data to coach underperforming staff.” Leaderboard Live sits atop TipJar’s Pulse Dashboard, where managers and owners can view tipping activity and alert history in real-time across multiple locations. Combined with TipTracker Alerts and TeamSync, organizations can celebrate rank climbs via pop-up messages on staff devices, broadcast surge notifications, and ensure team members stay informed and motivated throughout their shifts. “Implementing Leaderboard Live in our five café locations has completely transformed our morning rush,” said Shift Shawn, a café shift lead and early adopter. “Seeing our team’s names light up on the screen boosts morale instantly. People compete in good spirit, and we consistently hit new tipping records. The social media snapshots also draw customers in—we’ve had patrons mention they came just to tip their favorite barista!” TipJar is rolling out Leaderboard Live to all ProStylist, NewBarista, and Multi Molly user types beginning July 1, 2025. Existing customers will receive free access during an introductory period, while new sign-ups through December 31, 2025, will enjoy a 20% discount on premium leaderboard themes and analytics add-ons.

TipJar Unveils Surge Predictor and SmartScheduler Integration to Maximize Earnings During Tip Surges

Imagined Press Article

CHICAGO, 2025-06-20 – TipJar, the premier automated digital tipping platform for independent salon and café professionals, today rolled out a powerful combination of Surge Predictor and SmartScheduler, two cutting-edge features that anticipate tipping surges up to two hours in advance and recommend staffing adjustments to capitalize on peak demand. This integrated solution helps professionals and managers optimize coverage, reduce downtime, and boost overall tip revenue by up to 20% during high-traffic intervals. As service providers navigate unpredictable customer flow, under- or over-staffing can erode profitability and service quality. Surge Predictor leverages historical tipping data, real-time trends, and machine learning algorithms to forecast imminent tip spikes, while SmartScheduler uses those insights to propose optimized shift adjustments. Together, they ensure teams are prepared, customers receive timely attention, and no tipping opportunity is left behind. Core components of the Surge Predictor and SmartScheduler integration include: • Real-Time Forecasting: Surge Predictor analyzes multiple data streams—past tipping patterns, seasonal trends, weather conditions, local events—to deliver reliable predictions of tipping surges 30 minutes to two hours ahead. • Customizable Alerts: Users set personalized threshold conditions (e.g., 20% tip volume bump or $100/hour increase), triggering in-app notifications and SMS messages that inform staff and managers of upcoming peaks. • SmartShift Recommendations: SmartScheduler syncs with existing calendar and shift management tools, suggesting optimal staffing adjustments—such as calling in an extra barista or delaying lunch breaks—ensuring peak coverage without unnecessary labor costs. • Pulse Dashboard Insights: A unified interface displays tipping activity, forecast accuracy metrics, and alert histories, enabling data-driven decision-making and continuous optimization. • TeamSync Broadcasts: When a surge alert is activated, TipJar automatically notifies the entire team, allowing for coordinated responses, equipment setup, and pre-emptive inventory checks. “Predicting tipping surges and aligning staffing in real time is a game-changer for independent service professionals,” said TipJar Chief Technology Officer Eric Lin. “By anticipating when customers are most likely to tip, and ensuring the right team is available, we are empowering businesses to elevate service, capitalize on demand, and maximize earnings.” Over the course of a three-month beta trial in fifteen diverse locations—ranging from busy urban salons to niche coffee shops—Surge Predictor and SmartScheduler combined to increase tip revenue during surge windows by an average of 18%. Participating teams reported fewer service delays, improved customer satisfaction scores, and reduced labor idle time by 12%. “Surge Predictor’s forecast gave us a heads-up about a big wedding party rush, and SmartScheduler helped me bring in two extra stylists just before the event,” said Event Emma, a traveling event hairstylist and program participant. “I saw a 25% tip boost compared to similar-sized weddings, and customers complimented the seamless service.” TipJar’s SmartScheduler also integrates with popular third-party workforce management platforms, providing flexible export options and shift templates that reflect each business’s unique workflows. Managers can accept or modify recommended adjustments with a single click, and any changes sync automatically with staff calendars and payroll systems. Surge Predictor and SmartScheduler are available immediately to all existing TipJar customers at no additional cost. New users who sign up by August 31, 2025, will receive a complimentary one-month trial of advanced predictive analytics and scheduling recommendations.
